Question about Panasonic PT-61G53 61 in. Rear Projection Television
Hi, i have a 10 yr old projection tv that JUST recently the picture started flickering and distorting. I heard opening it up and re-soldering would be a good idea...?
This is a common problem. Your convergence has gone out.
Common symptoms are...
1) 3D Video
2) Warped Video
3) Convergence menu does not adjust the red or blue correctly. 4) TV Chirps

You said it is Distorting, If the distortion looks "3d" or separate red or green or blue images. You may have a bad solder connection on the convergence ic's they are located on a large heat sink the part number on the ic will begin with STK392- ??? there will be two of them and the pins will need re-soldered, or the part will have to be replaced. If you even just solder the pins it is a good idea to check and see if the heat sink compound has hardened it is a white grease between the heat sink and the component, if this has turned hard it needs replaced. If soldering does not fix the problem these ic's could still be bad, and need changed, but before i would do this i would tap on the chassis with the but of my screwdriver to see if the picture flickers. This being done with the set on and many dangerous voltages present. Soldering the chassis of course with the set unplugged.
I don't recommend doing this repair yourself because of the dangers involved with electrical shock even with the tv unplugged.
If you called a serviceman the repair might run around $300.00.
