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.

The remote won't work
Is its a Sharp Remote? or a Generic
A) Check Batteries
B) If a sharp aquos remote there is a function button on the right top side - insure that TV is selected. TV led will light
C) On left side there is a red TV power button press and insure the red led on the remote lights.
D) IF Tv does not turn on then you may have a problem with
the sensor inside the tv.
Only real way of verifying it is not The Remote sensor is by trying another remote. If you have a Cable or Universal follow the instructions for a Sharp TV and try that. If it works problem is with the Sharp Remote if it doesnt its your remote sensor inside the tv.
Hope this helps.

How to turn closed caption
If the cc button on your Sharp remote control isn't turning them off then the captions may be coming from your cable box. The hidden menu to access closed captioning on the cable box is usually found by turning it off and then (yes I did say turn the cable box off) then press the menu button on the front of it immediately after turning it off. Then you navigate down to captions and disable them. When you turn the cable box back on the captions should no longer be there.

Tv is on for a
It's the problem of overheating in the power supply board of the TV.on the power supply board of the tv there are few capacitors and IC.any of this ic is got short or may be weak.so due to this when you start the TV the current passes from electric outlet to the power supply board of TV.but when the current passes from that weak/faulty part at that time current gets stopped or slow and the board overheats and TV shuts off. this is a common problem faced by many other users too.the possible option to solve this issue is to check the power supply board by a meter and continuity tester and replace the faulty component on the board which is short due to which power supply board is getting overheated.its bit technical job but yes its not at all a costly repair to do or get it done by the technician. for required parts it can be easily available from local electronic hardware shop.
Hoping that the solution will help to solve the problem....
