SOURCE: LC-26DV24U white screen only

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/

SOURCE: I have a Sharp AQUOS LC-32D47UA 32", black box

Press the cc button on your remote control. You want cc to be off. Play around with the cc button to become comfortable. Press it over and over again. Observed that a different closed captioning option appears on your screen each time you press the cc button. Now press cc and when it says cc off do not press the button anymore.

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.
