Question about Sharp Aquos LC-37D90U Television

1 Answer

THE SET WILL NOT POWER ON. The blue power light blinks every second. I have unplugged the set several times for longer periods each time without change to the problem. The set is a Sharp LC-37D90U. The set always had little mysterious problems that seemed to cure itself since new. One problem was that the set would not turn off and produced a picture as if you were looking through a window screen and a not so clear hazy two tone gray picture. That only happened twice. Otherwise the picture was very sharp.

Try resetting the TV. Here's how to do it - Unplug the TV's power cable. Keep the Channel Down and Volume Up buttons on the TV pressed and plug the power cable back into the outlet. You will hear a click when you plug it back in if the reset is successful. Hopefully this should restore your video and audio.

SOURCE: flat screen needed

You can have them repaired using a TV Repair guy but often it costs as much as a brand new tv.
My daughter broke my $1,600 LCD. It would have cost $1,200 to fix.. so I just bought a new one.After that I picked up a TV screen protector called TV Armor http://www.tv-armor.com Its designed to protect the TV from damage. Now I dont have to worry anymore when she is playing near it. It works really well.

SOURCE: Sharp Aquos turns itself off

How many times per second does the POWER led blink? (dont worry about the OPC).

1x per second (constant, steady blink) = bad inverter/lamps
2x per second = bad power supply
3x per second = bad main board

You can buy the parts online and fix if yourself!!

SOURCE: Turns itself off

Sharp LC-13AV4U - turn it on and in ten seconds it turns off.
Happens every time.
Any Ideas?
-----------------------------------------------
DO THIS AT YOUR OWN RISK!
This is NOT a fix, this is a permanent band-aid.
All you need is a phillips head and tiny diagonal cutters....
Heck, even a nail clipper would do it.
Just disable that faulty protection shut-down circuit!
Remove all the screws from the back cover
and look at the main board with the
unplugged! power cord towards you.
In the upper right corner of the board, you will find
a tiny red-striped zener diode, labeled as D409.
It is to the right of an electrolytic capacitor marked C403.
Snip this diode, at either end, or snip both ends and discard it.
Re-assemble the TV.....and you just got your tv back!.
I only run mine when I am sitting in front of it,
I never leave it running unattended....just in case!
Don't blame me it yours burns up....but mine is just fine.

I have the vs 60719


This set was made around 2001 and should have the self check feature. Unplug set and then plug back in and try to turn set on----if green power light comes on for a few seconds and goes off--ON the front of the set press and hold menu and input buttons together for several seconds and then release--------------power light should blink a two digit error code and repeat it several times.

1 blinks, 2 blinks a pause and then repeats(1,2 is no error found.)

Hi,

The Standby/Power light of the TV blinks when there is any internal malfunction in the TV. The self-diagnostic function of the TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue.

Few examples are given below; some of the issues may be resolved without the need for service.
1 blink / 2 blinks / 5 blinks: - This indicates that there may be a power-related problem with your set.
3 blinks: - This indicates that there may be a power-related problem with your set. The set will need to be serviced to allow a technician to determine the specific issue that needs to be repaired. If the power light flashes three times in sequence in a Lamp TV, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
4 blinks: - This indicates that there may be a back light or lamp power problem.
6 blinks: - This indicates that there is some kind of audio problem with your set.
7 blinks: - This indicates that there is a temperature problem with your set. Please check to make sure that the air vents on the sides and back of the set are not blocked or clogged and there is adequate ventilation around the television. We recommend that you check and clean the vents periodically to make sure the set receives adequate air flow. If the problem continues, the set will need to be serviced.
8 blinks: - This indicates that there may be a video-related problem with your set. If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset:
Try the following steps to check if the issue can be resolved.
Turn off the television.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.

If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.

If the issue continues to occur, service may be required.

When the tv plugged up the power led blinks 3 times. When the power button is pressed the tv comes on for three seconds and turns back off. What could be the problem? Could this be a convergence problem?


Do the self check when power light goes out:

ON front of set (not remote) press and hold both the Menu and Input (Device) buttons at same time for 5 seconds or longer and release both buttons.

Power light will blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it several times.

Let me know code.

This is usually an indication of a failure in the scan amplifier sections. When the scan amplifiers or high voltage sections fail, the main power supply will usually also require servicing.

It is very common that the fly-back and high voltage multiplier and also the horizontal output stage fails in these sets. Along with it, the power supply will usually require to be serviced. On rare occasions, the vertical deflection amp fails.
