I have the exact same problem myself. I have a 1" black bar at the top of the screen, followed by about 3" of white horizontal lines. I also have the red, blue, and green lines at start up. I just bought this TV like, 7 months ago, too. Needless to say, I'm a little cranky at Philips right now.

Any help would be greatly appreciated.

Thanks.

P. S. Just in case it helps, my TV is a Philips model# 27PT6441/37 27" Stereo Flatsreen TV.

You have defective filter capacitor/s in the vertical circuit. Or defective solder connections on the pins of the vertical ic.

Thanks for the help, friend...

Now...how I should go about fixing this, or should I just give in and take it to a repair shop? I'm leaning towards the repair shop, but I might just give up completely and get a new television.

Thanks in advance.

RE: phillips tv white horizontal lines at top of the screen

I recently had my phillips 27" model 27PT6341/07 repaired after warranty expired due to white lines appearing at the top of the screen. The shop advised that it was a capacitor giving me the problem. So, after getting it back, I examined the repair job and the shop had replaced a capacitor at the back of the main board, next to the rear rca inputs. It is labeled 10uf 100v. I was told that it would fail again soon because it is a manufactures defect. For me it is at location 2465. Here are a couple of photos of the part.

I have a phillips 32pt5441/37. it's a 32" tv. I'm also having the same problems with the horizontal lines across the top. I wonder if the same part is defective. I called radio shack and they only have the 50v part not the 100v. if it's the same part, could it only be bought at a dealer or only repair guys have the part?

Thanks in advance!

Thanks to siestamagic I replaced the cap and the problem is resolved.
malietoa, do not put in any component with a lower voltage rating.
I bought my 10uf 100v at an electronics supply for 35 cents.

RE: phillips tv white horizontal lines at top of the screen

Thanks to siestamagic, I was able to repair this exact same problem as well. No more lines on the screen and everyone is happy.

My TV model is: 27PT9015D/37

I could not find any 10uF 100v capacitors in my area so I used two 22uF 50v capacitors in series instead. All is well and it was straightforward to do.

I put some of the pictures to help others here:

Does anyone know if the 10uf 100v capacitor is pos/neg?

RE: phillips tv white horizontal lines at top of the screen

I have replaced my capacitor and now I can not get the television to turn on. The green power button flashes five times and the television remains off. Any ideas?

RE: phillips tv white horizontal lines at top of the screen

I have the same problem. I replace capacitor with 10 uf 250v, and picture is better but tv shuts down after 1-2 minutes and the green power light flashes 36-5-1 code. Should I replace again with a 100 volt?

RE: phillips tv white horizontal lines at top of the screen

if you need a 10uf 100v capacitor let me know... I had to purchase 10 at a time and only needed 1 - but it did fix the problem...

RE: phillips tv white horizontal lines at top of the screen

Had same problem. Got a 10uf 100v capacitor at www.allspectrum.com for $3.71 including shipping. Repair took about 20" with most of the time spent removing the back of the TV. Some good pictures at:
