Hello,
Since you still get the sound it looks like that your inverter board is gone. Try to check if your Tv works with any external device for example Dvd or blue ray player if it works fine then you know that your tunes is out. Either way you have to change the main board. I can provide you more information on what part no you need for your TV, just leave a comment .

Please let me know if you have any further questions or concerns.

Thanks.

First check to see if the inverter board is getting the 24vdc from the power supply. There are fuses on the inverter board also.

Hello, it sounds like you need to replace the inverter board on this unit. I would recommend opening the unit from the back cover, get the part # for the inverter board (long green board normally running accross the edge of the TV) and go to www.shopjimmy.com, they should have it in stock and if not you can try www.invertercentral.com, they should also have it.

TV turns on screen is fine. Screen goes black


The problem can be bad caps in the power supply, or the backlight inverter board is bad, depends on how much you know about repairing electronics, you may want to look inside first for bad caps. You can look for replacement boards here: www.shopjimmy.com
But report back what you see inside first so we can you further. My had scrambled picture after warm up, yours will more likely to have this problem later on also. http://s807.photobucket.com/albums/yy352/budm/LTV-32W3HD/
