I think you are talking about T-Con board (lcd controller board) mounted at top middle of lcd panel.
It is considered part of lcd panel and manuals has no details about test for signal, only way to swap it with same board.
Make sure flexible wires from lcd panel are intact or plugged properly in connectors and LVDS cable from video board is hooked in T-Con board securely.
Thanks.

I have a sharp LC-37D40U that will not power on. The power light blinks 1 time every second. I held the input and volume - button while plugging the TV on and the TV cuts on and then cuts right back off,...


OK if you have blinking red light.

Try to open the cover then disconnect the inverter board after that try to power it on again..

If the light stays in blue (LIT) and of course you don't have picture or backlight you have faulty inverter board that need to be replace.

MY TV WENT OUT LAST NIGHT THE POWEWR LIGHT JUST FLASH AND NO PICTURE IT IS A SHARP LCD 32 '


Hello; Your model # shows that is a 30 in. set. First try unplugging both pieces and plug both back in a minute or longer (doesn't matter). If still bad, your monitor has bad inverter boards or main unit. The set has 2 or 4 of them. You must replace all. About $700.00. Sharp told me to replace all 4 , but I was able to force them to stay on, which proved they were OK. Later I took in the same model for repair. I swapped the main units ( the big board in a metal box ) and my first set started working! The Main unit is not available, but it can be sent to Sharp for repair ( about $250 - $300 ). The swap that I did proves the problem can be inverters OR the main unit. A lot to gamble with here! You may find these boards cheap on the net ( EBAY, Shop Jimmys dot com & many others. To get your part #'s go to Encompass Parts dot com and key in your model # . John

I have picture ,but no sound


Test: You might see a pic by shining a bright light against the screen. (Halogen can burn a spot if too close for too long like 15 seconds). If so, you probably have an inverter, backlight tube or coil/driver board problem. Some of these units have a bad ground on the tube driver coil board which can be shimmed and/or tightened. Sometimes a simple car light tester (continuity tester with a 12v bulb) from casing/mount ground to any of the negative (upper usually) side of the backlight driver coils will light the screen and reveal if and which tube is non functional. I leave one dome light running in such ground position one of my TVs at all times for regulation and night dimming.

No picture, has sound


i have the same issue and after removing the back and doing a voltage test on cp506 and found the 24vdc that was suppose to be there lead me to the back light inverter. a very common problem for these tv's and if you can take a voltage test of vdc then you can confirm it! one problem the manufacture does not sell it seperate from the lcd panel so it is very expencive and to find them use they are hard to find because of them being a common problem! good luck and if you need help taking the voltage test let me know!

Sharp aquos model LC-32D40U screen goes black


The Sharp TV model LC32D40U / 41U "Black Screen problem" is a very well known issue. The inverter is losing ground contact which will prevent the back-light from staying on. The solution is to re-tighten six screws on the inverter board. You also would want to clean the copper contacts on then bottom of the inverter where the screws go through. Access to the inverter board will require some disassembly. Plan on taking at least three hours to repair. See the photo for the location of the screws. Use some "blue" locktight" on these six screws. There is actually a Sharp Technical Service Bulletin that describes these screws. Sharp wants you to replace these screws with a newer version. They cost at least $2.50 each! I think my method will work just as good using the "Locktight"_548.jpg_547.jpg
