Re: Picture caves in.
This unit quite often develops bad solder connections on the pins of the convergence ic's. Carefully removing the chasis from the unit (marking the connectors you loosen to do so) and then resolder all pins of the large stk ic's mounted on the large heat sinks will fix this problem most times. Please note that continued use with this problem will cause those ic's to fail and then will need to be replaced.

this is convergence failure, but on this model, its usually solder connections before the chips totally fail. here is my tutorial, let me know if you need help diving in and re-soldering http://www.fixya.com/support/r5001731-convergence_diagnosing_convergence Let me know if I can be of further assistance.
assuming that you have adjusted the convergence and this had no effect. you might have some blown convergence chips and/or resistors. these make the 3 color line up with each other.. my 55 in phillips did the same thing and the more i used it the worst it got. first it was the blue and the red and finally the green., replaced chips and resistors and the problem went away... good luck.. a lot of soldering involved. but the chips are only like 11.00 each and the resistors are like ten for all three.
This is a convergence problem that can be either poor solder connections on the convergence ICs or defective ICs. If you can solder you can fix this yourself. Update this if you wish to attempt the repair and I'll supply additional details and instructions.
this is a indication of convergence problem. the curved picture indicates total or a complete loss of convergence power. I first recomend you read the artilce in tips in tricks section. the fl231 problem it might be this if you do not have the convergence options in setup of customer menu. if not it might be a convergence power board issue
This doesn't sound like a programming issue. I had a very similar problem about 6 months ago and I fixed problem. I had cold solder joint on the video power board. It was the board in the middle. The power supply was to the right. The video board had a driver with a bunch of legs. About 7 solder joint where cold or loose. I solder the board and my mitsu wide screen was fixed. Hope this helps.
