Classic case of LCD inverter failure. To confirm take a flashlight and flash it on the screen in close range from different angles. See if you notice a dull image and let me know, so that I can help you replace it.

    You should replace the backlight inverter board. If you take off the back cover you fill find it on the left hand side of the chassis. Get me the part number off it and I will find you a replacement. I have found a replacement on shopjimmy. Just confirm that the part number (75012526)matches with the one in your set before ordering it. Replacing it should be very easy. You just have to unplug the connectors from the old board, plug them into the new one and thats it. Your set will work like new again!

Toshiba 37 lcd tv picture gone sound remains ok looked in back none of the backlighting is lit any ideas.when turned power off heard a pop


The power supply module will be the first place to look, it may have bad DC filter caps, blown or burnt parts, cold solder joints, etc.
Here is the service manual:

My Toshiba 32AV500U - the picture went blank.


This problem usually happens when the lamp runs out, verify how old is your TV, lamps have a life spend of aprox. 3 years, most likely you would have to replace the bulb so your TV can start running again!!

When I Turn on my toshiba 32AV500U there is sound but no picture


The problem isn't with the lcd panel, its with toshiba not willing to sell the backlight master or slave inverters seperately from the panel. If you check either the master or slave will have a blown 5 amp fuse, ussually 2 or more transistors inline with the transformer will be shorted.
