Convergence problem on rear projection Panasonic PT53WX42?

Hello, I have a 5-year old rear projection Panasonic PT53WX42 TV. The TV was working great until the other night. I put the TV on and it appeared that it was out of convergence. I can see red, blue & green images of everything that is on the screen. I tried to adjust the convergence but with no luck. The problem appears worse on the right side of the screen (the red image is more prevalent there). Nothing was changed with my set-up (i.e. speakers, lamps and other items around the TV). Does anyone have an idea of what the problem might be? I don't have any experience with TV repair, but I want to know if I need to contact a service provider to repair the TV or can i repair it with a little bit of guidance. Thanks for all your help. Anthony

If you do not have any electronic experience I would doubt that I could talk you through the repair. You have bad convergence ICs. This is a common problem. I sometimes do a set a day. They are not expensive and not hard to replace if you have done it or have an electronics background. Cost should be between $100 and $200 US. Call a reputable repair shop and you should have it working fine in no time. Good luck.

You have a bad convergence circuit. You will need to replace the convergence ICs minimum and could have a problem with the digital convergence box. I have a tip at which explains the problem, where to get the parts at the best price and how to complete the repair.

Thanks for using FixYa and for the great rating.

Most likely the Li-Fi lamp is bad. If it is and your TV is less than 5 years old the lamp is covered under warranty by Panasonic but must be replaced by a Panasonic dealer. If its less than 2 years the labor is also covered. If its less than 5 years old and it appears the lamp isn't firing I would contact Panasonic to have a technician look it.

Decoding the number of beeps may be possible with the owner's guide but this type of problem is normally due to a failed power supply.
These are often mounted on separate boards located in the bottom of your set and can be identified by the much larger parts you see on the board and possibly its relationship to the AC cord coming in. While these can be repaired, the cost of that will approach the cost of a new assembly.
Unfortunately, modern, more energy-efficient power supplies have some critical components that if bought cheap, don't last very long and frankly, 5 years isn't bad, I read of many dead within the first year.
