SOURCE: Sound No Picture Sanyo LCD WIDE Screen HDTV

Hello heck75,

I wrote this for another post but it applies here also:
This sounds like your inverter or back-light has gone out. What you can do to test this is to turn the TV on and then turn off all of the lights until the room is dark. Then shine a flashlight at an angle on the screen and see if you can see a picture. If you can the back-light and or inverter has malfunctioned. If this is the case, then I would suggest that you have a qualified TV technician fix this problem, but first ask for a estimate because the inverters and back-lights are sometimes part of the screen and is it is you might as well buy a new TV.

If the inverter is a separate board, If you have a background in electronics you might be able to repair the board, however if you do not have a background in electronics, again I would suggest getting a qualified TV technician to work on your set.

I hope this helps,

Thank you,

Hello, a no picture with sound condition can be caused by several things inside your LCD TV. A power supply circuit with a missing voltage source could be one cause of the problem, an inverter circuit or HV circuit could be another. The best answer to your question is to have it checked out by a qualified tech. If you have a little knowledge of electronics you could try to repair it yourself, you can sign up for our great tech support where they can assist you on the steps to take to get it up and running.

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! ! ! !

SOURCE: sanyo hdtv lcd flat screen--no picture and no sound

first just for trying--unplug set for a few minutes and plug it back to see if it resets.

If not someone will have to open set and check voltages on Power board to see if there or not.

There is another issue common if set 1-2 years old but that is the set at first has to be turned on several times to get it on--let me know if you had that one and I will still advise you.
