There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Sanyo lcd tv 20"has sound but no picture


0ne of 3 has failed:
(in order of probability):

1. Backlight inverter
2. Power Supply
3. Backlight

Please seek the expertise of an experienced TV repair technician - as they contain potentially lethal voltages that must be properly discharged before work can begin.

Thanks! ! ! !

SANYO Model CLT2054 Television


sounds a lot like you lost the video driver or control board functionality. From the 'decay' of your image, with sound still working, and all else being good, you're primed for a new video controller. Are you inclined to do the repair yourself? The service manuals are hard to get online, but the local service center MIGHT sell you one.

Have a Sanyo CLT2054 Have flickering picture looks like a strobe; sound is fine


Sanyo CLT 2054 flickering problem is a power supply issue. You don't need to replace it if you can desolder, and solder. Break the case apart that is connected to the ac power cord. Remove the aluminum cover from the DC out end of the PCB. Unsolder, and replace capacitors C9 & C12 (1000mf 16v). Super glue the case back together, and watch TV. Good Luck...............Don't use cheap capacitors use caps that have a low ESR.
