We chatted previously, remember to reseat the cables that go to the section of the screen that is distorted. The Y drive boards will be on the left side of the tv (when viewed from back) and there will be about 8 ribbon cables hooking these board to the plasma panel. If you can, look at each square black chip on the board. Each chip drives the picture (row - horizontally) so one chip may be blown causing your issue. It will likely have a small pin sized hole burned in it if bad. You can replace the corresponding board (upper y, lower y) to fix the issue. Hopefully reseating the cables will do it, for a part free fix. Let me know when you get the TV open and I'll assist more. Thanks again!

I have a Phillips LCD tv model #42PF7421D/37. and


I know on the plasma TV's it was a matter of updating or downloading and re-installing the firmware/software for the TV to fix the issue. Go to the following page and if the model you have is indeed a 42PF7421D/37 download the software on the page. Make sure you follow the installation instructions to update the software otherwise the set will become a 150 lb paper weight.

you will need the replacement screens. Phillips doesnt make them anylonger, they are exspensive. But you can get one by leaving a email at the following link with the model number of your set and what youre needing.

Need the correct convergence IC number for my Phillips Phillips Magnavox rear projection tv P6034C. I am getting the double picture syndrome . It also appears as if I cannot adjust the red convergence...


Thats not the full model number should be something like 43P6034C or etc. Please respond to this same post and I will let you know the correct Ics and resistors because phillips / magnavox will always burn at least 2 often 4 of the convergence resistors as well.

Magnavox Plasma HDTV Red light


I had a similar problem with my magnavox tv with the blinking light issue. Eventually it just didn't come one anymore. Looking at other forms they said the problem was a bad capacitor number 2074 located on the power supply board. When I opened my tv, I noticed that the capacitor was bulging and burnt up. I bought a new one labeled 2200uf 35v and did some solder to attach the new piece. Put the tv back together and it works like new. No more blinking light. I hope this helps.
