Question about Sharp LC-26DV24U 26 in. LCD HDTV/DVD Combo

LC-26DV24U white screen only

I have a LC-26DV24U that will power on to monochrome white/grey screen and will power off. Except for power button there is no response from any button and no other function. A call to an authorized Sharp repair station said it is probably the "main board" and will cost $200. I have the case open and have read some of your tutorials. Any help or advice?

The grey screen is caused by failed transistor for the switched 12vdc for the T-CON board, same as my pictures here (my does not have the DVD), but it can also be the main 12vdc itself that is bad, you will have to do some probing. Since the screen is grey, you will not be able to tell if the set really function or not. http://s807.photobucket.com/albums/yy352/budm/Sharp%20LC-26SB24U/

Here is the free service manual that you will need: http://elektrotanya.com/?q=showresult&megnev=SHARP&megnev2=LC-26DV24U%20&kategoria=&kat2=all

How do I Fix my tv? My TV plays for awhile and then the screen turns white. Sound is good even when screen is white.


sounds like maybe something is begining to go. I usually recommend that it is reset to factory default through the menus available from a remote control. If, after resetting, the fault persists it must be something to do with the electronic hardware and the fault shoud be diadnosed by a qualified technician.

How to troubleshoot lcd tv


If you are using the ANTENNA input mode of the TV and should be receiving a local station on a properly chosen channel then something is wrong with the RF or IF section inside the TV. If you can connect an external video source to the TV see if that works while selecting the proper input mode.

My sharp LC-26DV24U is displaying a white screen only.


I have the same model Sharp TV with the same symptoms. The TV would sometimes work perfectly, then go to white screen (audio OK) and sometimes back to working perfectly again.

I saw Posts saying to check F404 and Q413 - My fuse F404 was not blown, and replacing the Q413 transistor did not fix it.

On Q413 I had about 12.4 VDC on the Emitter, 12.3 VDC on the Base and about 1.5 VDC on the Collector. My service manual called for 11.6 VDC on the Base lead. As a Test, I used a 150 Ohm resistor from Q413 Base to metal chassis ground, and that made the TV work OK.

I replaced the Q419 NPN silicon driver transistor, and now the TV has been restored to 100% proper operation.

I hope that helps someone else down the line.
