Philips Magnavox TV problem

tomknixx
19 years ago

My one year old daughter was recently playing with the TV (Philips Magnavox 25TS56CI) remote controller and turned the TV on and off repeatedly. Now, when you turn the TV on, there is perfect audio but a white screen with horizontal lines in it. The sceen then looses the horizontal lines after about 5 seconds (the sound remains perfect during all of this), turns pure white, and then automatically shuts off after another 5 seconds. We have tried waiting a few days before turning it on again thinking that perhaps something was "over heated" but there is no change. The owners manual is less than helpful with this problem. Any suggestions?

    I have a Magnavox tv we bought in 2003. My 2 year old has "misplaced" the remote. He was pushing buttons on the tv last week and somehow turned on the child lock. We cannot get the tv to turn on anymore. I called Magnavox, but he said all I can do is order a new remote for $45.00!!! Isn't there something else we can do! HELP!

    I just got a new 27 inch magnavox stereo tv during black friday, it works fine except for the fact that i bought it to use as a second monitor for a computer. When ever I switch to the video in or s-video in on the tv My picture starts to form darkened areas as if the video is being burned into the tv. I'll switch it back and it will still be there until I turn off the tv. I know that it is not burning into the monitor due to a constant unchanging picture because it did the same thing during a video and every time it appears in the same spot. Is there any way to prevent darkened areas?

    The Problem we are having is this we turn on the TV and have sound, no picute for about 5 secs, then it will shut itself off and the power light will blink on and off. Any ideas on how to fix this will be greatly appreciated. Thanks again!

    I have a Philips projection TV model 9p5514c101. It is a 55" tv. The problem I have is the colors. I have tried to adjust them but just can't get it right. I call a place called the partstore and they believe that it is the focus/screen control, because even when I try to adjust it on the menu it will not really change that much. My question is... when I get the focus/screen control could anyone tell me how to adjust the knobs in the back. I have a red, green, blue focus knobs and red, green, blue color adjust knobs. Thank you for anyone that can help me.

    I have a TS3661C129 (36K800) that originally had the problem with the 10 ohm resistor on the PCB that connects to the CRT. The resistor was replaced, but with in a few weeks the video started pulsing and the horizonal linearity at the top and bottom was slightly to wide. When a picture with a significant brightness comes on the pulsing gets worse and shuts down. Checked the video amp (TDA6108jf) and found it a bit warm, but doesn't seem suffient to say it is overloaded or breaking down. Can you give me a suggestion as to the cure to the problem?

    My sister gave me her 5 year old Phillips Magnavox PTV835 but when I got it home it was doing the same thing as many of the readers describe: picture on...after 10 sec horizontal lines and then no picture but still has sound... I was so encouraged by everyone fixing their own tvs by replacing the resistor but when I took the back off of the tv, I was totally confused. How can you tell where the resistor is?

    Hi,

    I have a 25" Philips Magnavox TV (Model number: TS2556 C121, Serial #: 33471131) that had been working without any problems until yesterday, when it suddenly lost its sound. I can turn up and down the volume and that displays the volume level, but there is no sound. I've tried muting/un-muting as well to no effect. Also, I noticed that the smart picture and smart audio buttons do not have any effect either. And I can't change channels to Aux/DVD. The Closed captioning is working though.

    Reading through the posts, I tried to open it, but not sure how to open the back of the TV. Any help in this regard would be greatly appreciated.

    Thanks!

    Had a power surge to the house. Philips Model 25TS56C121 will not turn on. Philips Model 27PS55S121 will turn on but no picture and there is a clicking sound coming from inside the housing. Thanks for any help.

    I have a TS3259C1 model that was working fine. One day child was watching TV and we heard a pop. Then the TV clicks from the back (like an electrical relay click) about once a second. Have to unplug to make clicking stop. Plug it back in and clicking resumes. Nothing on screen.

    Another post for a different TV on another web site noted it could be "a shorted horizontal output transistor".

    Any thoughts.

    RE - Philips TV (32PS60B129)

    When I turn on the TV, the tv starts up then turns off. Eventually after a few on and offs the TV will work ok. When the TV finally does turn on the picture does not go all the way to the right and left side for a minute or two. After it does then the TV works just great.

    I have experience fixing electronics. Do you think it is the transistor driving the flyback transformer? (I had this problem on a different tv many years ago). If you think it would be difficult to fix, can you direct me to a schematic of the board so that I may try to fix it myself.

    Thanks

    Everytime I turn the TV on, CC1 is ON. Even if I turn it off, it still comes back on. The strange part is that when I toggle the CC settings via the remote, they appear in an orange window in the center of the screen, but when CC1 is on from Power-on, it appears in a red window at the top-left of the screen.

    Any idea how to turn it off for good?

    I have a 13" Magnavox (model number PR1350 B121, serial number 40896711) which was working fine until yesterday when our one year old was pushing buttons on the tv and now all that shows on the screen is the "introduction menu". We have to unplug the tv to get the tv off. When we plug the tv back in...it still plays the menu. Neither the buttons on the tv itself or the remote will work. Please help!

    Hi.Pee-Wee.
    I have a Philips Tv it has a flat not curved screen buts is not lcd its normal size.

    *made in- April 2004
    *Model#- 32PT6441/37
    *Chassis#- L04.1UAA
    *Serial#- YA1A0415005856

    The problem started with the volume going to max, but later progressed. Now when you turn it on the click comes but it takes a while for it to actually start. finally its on BUT NO Picture, there is however sound for about 2-3seconds maybee. after the sound stops it turns itself off - but isnt completely off because the green power light blinks 1 2 3, 1 2 , long 1 repeat-if blinking order makes a difference. and i really want to fix my big heavy 30sum inch tv.
    We took of the back of the tv slightly to see if the fuse was blown but it looked fine . I dont know anything about tvs. the fuse was all i could think of and theres a mess of cords and things i dont want to damage. I hope you can help the more detail the insturctions the better for me. its just not worth repairman fixing it. I hope you can help me it would be most appreciated.

    I am having the same problem with my Phillips Magnavox TS3254 TV. Chasis Model # 32Z500-7563. The TV starts and after a while the screen goes gray with white lines and shuts off. I have seen many postings to replace the R3340 resistor on the CRT circuit board. My model does not have #s that high on the CRT board. The circuit board # is GR6B-97 212974C0320B is also printed on the board. The resistors are labeled R54, R55, R60, etc....
    Can you tell me which resistor need replacement?

    Thanks

    My Philips TV which I've had for about 6 years stopped working. When I press the button to turn it on, the red light next to it flashes for about a second, then pauses, then flashes again for shorter. What is wrong with it and how can I fix it? Thanks!

    My Tv is Phillips-Magnavox Model#9P5514C101, Chassis PTV836. The whole TV works great with one exception; Component Input went bad one day. Black with squiggly horizontal white lines. I was wondering if anyone knew what the problem is. If so, I would greatly appreciate it since this is the only message board I have found with any useful information. Thank you.

    hey, i know this sounds like a dumb question but I guess i leaned on my remote somehow and i put closed captioning on my phillips magnavox tv. I have no idea how i did it, but now i can't figure out how to get rid of them. I have looked all through the menu and cant find it.

    please help, thank you

    T.V. turs on sometimes you can see a horizontal white line then turns right back off, you can push volume or channel buttons and it will do the same thing. Any ideas on how to fix this problem would be much appreciated!

    I have a Philips Magnavox Model 7P5441 C101 Television and when you try to turn it on there is a wire burn smell, so I took the back panel off and look into the board and had my wife to try to power it on with the remote and there is a round ceramic disk capacitor that sparks and is burned through.

    I got a magnifying glass and looked on the board and at the capacitor there is a number C811 it looks like or it could be CB11, it is the only Brown Round Ceramic disk Capacitor there on the right board when looking in from the back.

    I tried to call and get a schematic but can get no one to help me, I would appreciate very much if you could help. I was going to purchase a capacitor off of the internet that looks like it but I do not want to purchase the wrong one, and also if you do not mind in which way does it go in as the side with the numbers, I think they go toward the front of the Television correct?

    Please send help to my email address would you please, Thanks Again.

    Thank You
    Sincerely
    God Bless

    I have a Magnavox Model #TL7125 C122 that I bought used from a hotel where I used to work. My problem is that because it was a hotel tv it was slaved to a Master Remote that I obviously do not have. The display is stuck on and no matter what I am watching, whether it be cable or DVD, the number three shows in the lower lefthand corner. Is there any way to get rid of this without the remote? I am giving the tv to a financially stuck friend of mine and would like to have that problem taken care of for her. Any help would be appreciated.

    I am getting a 64" Magnavox tv from a friend, and she says that the flyback transformer is out. Is that a very big problem? And just where would I go to find one of these? Does the great Radio Shack carry these? Just thought I would ask...
    Thank You,

    I just started experiencing this morning my tv going on, on its own and off, constantly. No matter what I do, it does this. The only way to stop it from happening is unplugging it. I have had the tv for less than 3 years. It is a 20" Magnavox Flat Screen. Model #: 20MS3442/17
    Any help would be appreciated, so I don't have to throw it away cause I will not pay those high price tv repair bills.
    Thank You

    I have a 27PT5441/37 and there is no power. I changed the fuse, which was blown, and as soon as I placed a new one in, it blew. I have heard that it may be the transformer. Am I on the correct path or is there something else? Thanks for the help.

    I have had my Magnavox 27MS343S for several years. I have DirecTv hooked up to it and have been using an S-Video cable for the picture for many years. One day last week, suddenly the picture is in black/white only! Crystal clear still, but no color. I switched the mode over to "Cable" and the color works but the picture is not nearly as clear as in S-Video mode. Any suggestions would be very appreciated! :)

    I have a similar problem, the tv gets blurry and shuts off. I checked for 3340 on my crt board but couldn't find one, so I started testing resistors and found 3337 had no continuity. It has a red red pur gold and white color code. I'm guessing I should replace it but just wanna make sure I should replace it with the same size. Any help would be greatly appreciated.

    I have a 3 year old model 47MF437B/37 magnavox TV that has developed a "split" screen. That is to say, there is one picture but the color is darker on one half than the other, not much, but I can see it and it's driving me nuts. I called the service people and they reccomended rebooting the TV by pulling the power plug and holding the on / off in for one minute. It didn't help, any ideas? Thanks.
