You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Why is my color distorted on my 60737 hd tv???????


Try resetting the tv By pressing the power button on the set for 8 seconds if that doesn't work try unplugging your video source (cable box, sat box, ect) for 20 sec then plug in. if all those don't work then service is needed. the formatter board needs replacement.

Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time.

I have a Mitsubishi WS-65869 65 in. Rear Projection Television and it has created a wavey line and has distorted the image. i have a picture of it i can send. Any help. i can send pictures of screen.


If you see separation of colors (red, green) in this wavey line most likely you have problem with convergence circuit. Two convergence amps have to be replaced. They located in a middle of the TV boards attached to big aluminum radiator and they part number starts with letters "STK".
I would recommend to let professional with this repair. Should cost you about $250-$300.
Regards.

Picture on TV shuts down but sound still on.


If this RCA TV has a Chassis number of ITC222 then you need to call a tech to swap out the deflection circuit board for a new or rebuilt board. This RCA Chassis is a TV Techs worst nightmare to repair.

Long warm up time


you have a bad capacitor in the deflection circuit.You will need some diagnosing and testing to find which one. An ESR meter will make short work of that but they are expensive meters.

Tv repair?


The waviness is most likely a weak capacitor or leaky diode in the deflection circuit. The logo is burned into the tubes phosphorus from being left on the espn station all the time. That would require new tubes or have yours rebuilt either way that will be expensive. Repair the waviness should not be that expensive I would estimate a shop charges tobe between 150 and 300 depending on where you have the repairs done. Hope this helps.
