When I would turn on my 32 inch Magnavox the tv would have lots of lines everywhere and a horrible picture and then turn itself off after 10 sec. Finally I would get it to come on but on the sides of the tv te picture would squigle in and out on the sides just a little before clearing up and working normally. This has lasted about 4-5 months of dealing with the tv turning itself off after so many seconds but I usually always get it to work, eventually. Finally, now when I turn the TV on the channels or volume from the TV will turn channels/volume/menu on it's on and then the tv will shut off soon afterwards. Sometimes it's the TV will shut off and sometimes the picture will go black but I notice the tv is still on but not always and when I try to turn it back on the lines come back again. It is getting worse than before and I have only had the TV for a year. My question is what could be wrong with it? How much of an estimate would it cost to fix? Thanks, Brandy
