The GE (actually RCA) 46GW945 uses the PTK195 chassis. There is a separate power supply for the convergence circuits in those sets. The earlier versions used a switching transistor but most sets use the STK730-010 power IC. I have seen many of those IC's stop working after a power surge, resulting in very curved sides with screwy colors. You can remove the back and you will see the 2 main boards at the bottom of the set. The convergence power supply board is mounted above the board on the right (when viewed from the back) and has a pretty large black IC mounted on a little heat sink, labeled STK730-010. Replace that IC and the colors should return to normal. If you do not have experience replacing IC's and working on TV's then allow a qualified tech to handle it for you.

My tv has alot of different colors on the screen when your watching it and the top of the screen is bowed in and you can see a black space between the picture and the top of the tv what is wrong with it?

This is a problem with the convergence circuit. It is relatively easy to fix. It is caused by either poor solder connections or defective convergence ICs. Please update this with the model number of the set so I can provide the probable parts and costs.

Thanks,
Dan

I have a magnavox 52 inch tv the picture got a mirred look to it then went black but can still hear te sound can you tell me what's wrong

This is a very common failure on Projection sets. Its called a convergence problem.

You may have one or more of the following symptoms.
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • No Audio / No Video - Makes Chirping Sounds

You can see some examples and find a fix here...

TV Turning on and off, left side of picture is not lining up, bowed in center

Most likely you had a power surge issue that caused the tubes in your crt projection to malfunction. I would recommend having a service call done to find out the issue

Color problems

actually when JVC tv's turn green the light engine is going bad. I repair lots and lots of these. The engine can be rebuild for about $500 installed. IT is a known problem for us tv techs. I have 1 engine left if you know a tech who can install it. These sell for $300. This fixes the problem which is the green chip color breaking down and smearing. All whites look green. The best way to tell is to turn the color all the way down and see if you still see green tint. It works best on a black and whit picture if poss. but any will do. Usally it shows more in one section on the picture but is green all over. my number is 270-996-7629 if you have any questions.

GE 46GW945

Your problem is a bad main filter, a regulator IC ,and or a combination of a convergence problem along with a vertical IC going bad. This set is not something you should mess with unless your a trained tech. Please seek a pro to assist you with this repair. good Luck
