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.

I'm trying to hook up a sharp aquos tv to an rca surround sound receiver and it won't work? any suggestions? I have tried turning off the speakers on the tv....


First thing to do is get the owner manual for each and start checking both settings and actual hookup---usually a surround system will work on all types of sets---when in doubt read the owner manuals.

If need either manual Google that model number with "manual" to try to locate it.

As far as the set goes it may require either a variable audio output source or in some cases the out to be a fixed level.

My 32 inch Sharp Aquos acts like it isn't plugged in..The power light doesn't even come on...


Can you take the back off the set and check the fuse? Located to where the AC plug wire goes into the set. Can be checked with a ohmmeter for continuity. If bad do not exceed the amps of the original fuse when replacing because there may be a short in the circuit that will blow the new fuse and a higher amp may damage the set to a worse condition. Inspect the power supply for charred components across the AC line and replace.

TURN TV ON JUST PLAIN SCREEN (NO IMAGE), THEN HEAR A CLICK & TV TURNS ITSELF OFF- THEN ON AGAIN... CHANGED BATTERIES IN REMOTE & TRIED TO TURN TV ON DIRECTLY FROM TOP... NOTHING WORK. THIS IS A...


Do you see the backlight ever coming to the screen?

You will want to open the cover, disconnect the backlight inverter and try again to see if it will stay on even without an image.

If it does it's the inverter.

if it still shuts it's most likely (not guaranteed) either the power board itself or the main board.

A good tech should be able to test the power board independantly fairly quickly.

I need some information on buying a ac adapter or power cord for the Sharp Aquos Model LC-22SV2U.


Cord: http://www.newremotecontrol.com/catalog/dyn_accy_data.php?catnum=QACCD3097CEPA
Adapter: http://www.newremotecontrol.com/catalog/dyn_accy_data.php?catnum=UADP-0243CEPZ
On the adapter: I've seen them a LOT less expensive just recently. Google it and choose "shopping" to narrow results. There won't be many, but I think you'll find one at better price in just a few minutes. Try ebay as well; that's where I found repair parts for the same model. Good luck!
