My 32D40U would turn on for 5-10 seconds (Please Wait would appear) and the screen would go black. Sound Normal. It would also sometimes do this after running 5-10 minutes. I read somewhere that the inverter board would come loose and lose proper ground. I took the set apart, removed the board, and cleaned up the grounding points. I reassembled using some copper paste on the ground points and LockTite on the screws. I used some contact cleaner on all the connectors going to the board. I noticed two cables that are covered with copper shield tape where too tight at their connectors and repositioned the tape to give them some slack. The problem hasn't occurred since the fix.

SOURCE: Sharp aquos lcd screen goes blank

i was having these same problems with the screen going black, and i found that when i hit the back of my tv it would work sometimes. so, i improvised on some of the advice on this page and so far no problems. here is what i did (its very easy):

1. lay the tv on the floor and take off the back panel. (i think 12 screws)

2. on the right side of the tv (as you are looking at the back) you will notice a large metal covering that is held in place by 6 screws. unscrew these and remove the metal cover.

3. you will notice that the three screw holes on the left side of the board have some sort of metal or solder around them, in sort of a star pattern. when i looked closely i noticed that most of the metal (solder) was tarnished, or kind of blackened. (this must mean that the ground screws werent getting a good connection and this would explain why it would work sometimes when i hit it because it would vibrate the screws enough to get a good connection! )

so, take a pencil eraser and erase all the black or tarnish off the metal surrounding the screw holes. thats it! (to be safe i took some sandpaper and cleaned up the screw holes on the back of the metal covering, but i dont know if that was necessary)

at this point i followed another gentleman's advice to do a hard reset. this involved unplugging the 8 connections although i dont know if this was really necessary because i believe my problem was a ground issue. i did it just to be safe. his advice is on this site if you want to do this step.

4. i put everything back together and it worked! i performed a soft reset at this point which puts your tv back to factory settings. just go to menu>setup>reset>return to factory settings? yes
this will turn your tv off and back on. that's it. so far so good for me.

You must contact a svc co. This is a upper or lower buffer board problem and possibly a control board. Nothing you have done wrong, it just happened.

If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

My sharp aquos LC-60E79U has no picture. Perhaps I have a backlight problem?


. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Why am I not able to change channel on Sharp Aquos television?


Try changing channels with the button on the TV to make sure the remote is not bad. Sometimes one or just a few buttons on the remote will quit functioning. It is usually the ones that are used the most. What channel is the TV on? If it is 3 or 4 or one of the aux inputs; it may have been told to stay that way because the channels were changed by a cable box. Go to set up and scan channels into memory. After it has started, do not stop it until it says on the screen that is finished. If you stoop it before it has completed the scan, the TV will keep its original program. (one channel)

Sharp Aquos HD black screen. Sound but no picture. Remote will turn TV on, but will not change inputs or do anything else. Happened suddenly.


Look at the venting grills to see if you can see any white lights inside, if there is no light, the backlight inverter board may have gone out or the main power supply for the inverter board is not working. If you do see the lights then the problem can be in the main controller board.

Usually the DISPLAY Button on your TV remote will toggle through several different functions: 1 sec, 5 sec, Always on..... Press button until display on TV is off. Or see if there is an ON SCREEN DISPLAY portion in the TV Menu and turn it to off if you have not checked that already.

I have a Sharp LC40LE511E. There is some sort of fault and I don't know what it is? Blinking LED lights, no picture. So, when plugged in, the power LED is red as it should be on standby. Press on button either on the TV or on the remote, and it flashes green as if it is about to come on, then it flashes back to red, and then blinks between green and red until unplugged. I have shined lights up close, but the pixels seem completely off so I don't think it's the backlights. It could be the backlights if the TV somehow knows and is preventing them from turning on, but it just doesn't feel like that's the problem. All the capacitors are fine, and in fact, all the boards and components look in quite good condition. As it is flashing green and red, I figured it could be a reset issue. The previous owner had no remote so perhaps they kept over pressing certain buttons on the TV it's self, causing some sort of crash. So, I have tried the old unplug, volume down and channel up, plug in, turn on etc. Nothing happened. Not sure if that was the right way round for this model but it seems to be the standard reset for all of them. Yes there are slightly different variations, but that is the only one I have tried, both with the onboard buttons, and the new remote buttons. The remote is legit and seems to work perfectly fine. Tried asking the justanswer.com people, and never got a direct response re: the actual fault code that blinking red then green, means. If anyone could at least tell me that, I could be on my way to figuring out what is actually wrong with it, or how to reset it. As the pixels seem to be completely off, it may be a power board failure, but then, why would it be teasing me with flashing green? I am perplexed. Any ideas would be much appreciated thanks. It's 109 pound for a new one, so it's really not worth getting anyone to take a look.
