Sharp aquos lc26sh12u no menu screen appears

I am working on a 26 inch lcd flat panel. It started blowing a fuse and would blow fuse again as soon as replaced the fuse so i replaced faulty parts by exchanging parts with another lc26sh12u i had with a broken screen. Now fuse no longer blows and tv powers on but all i get is a blue screen and no menu or any kind of display. it will not respond to remote menu commands or any kind of button command. It only turns on and off with remote or with tv buttons can anybody tell me how to fix this problem?

    I have a Sharp LC-26SH12U problem is almost the same. my set comes on for about 2 minutes then goes to the blue screen. then if i turn it off and back on, it might run for a minute, then the blue screen. Any idea what might cause this problem?

    Changed batteries on remote and even bought a replacement remote. TV only responds to commands when remote is directly in front of tv and only 12 inches away. Can the sensor be fixed?

As you have a good screen, I would check ebay for the display controllers as there are so many available after shipment drops and kids with hard toys.
what you have been troubleshooting so far is analog , now its likely a digital issue , all you can look for is the the cpu is running,
is it getting the 5v + and the say 20 or so volts.

Horizontal lines showing behind tv menu


Hello,
Normally the menu is generated in the LCD Control Unit. If your menu looks good, but the defect is behind the menu, I would suspect the Main PCB. Good luck to you. Part# is DUNTKD934FM01-V1.

Sounds like you have bad capacitors somewhere in the TV. If none of them are bad, you could also have loose grounding screws on the inverter shield. It is common for this TV and simply retightning them will keep the backlight on again.

Can't find 2A 125v fuse replacement for on-off will 250v be OK?


There is no difference between a 125v and 250v fuse. The most important thing is the 2Amp. This fuse is probably the line fuse and could be the only trouble and may have blow with a line surge. Make sure the 2A you use is a Fast Blow Type. If it does blow again you most likely have a internal power supply failure.

Fuse F3701 is blow-up after few munites turns on. If replace a fuse F3701 again, it work, but the set turns of any time, check the set: Fuse F3701 is blow again?


Look at the power board " the one with the fuse" for capacitors that look puffed at the top or leaking at the bottom. If these are leaky the voltage drop will cause the current to rise and pop the fuse. After a time the caps will get bad enough that the set will stop working and may cause more problems.
