Tv switches off

Hi,purchased television last week and all was fine.this morning i switched it on and after fourty seconds the television turned itself off.i have read through the manual and double checked that i have set it up properly.the timer is set to off so that is not the problem.when it turns itself off it does not go to stand goes get the telly to come on again you have to switch it off at the wall and after a minute switch it on at the wall then on at the telly.after fourty seconds pass it turns off states in the manual that it may be overheating but it does not stay on long enough to overheat.just before the television turns off the picture vanishes.the big question is,is my brand new telly goosed.your help in this matter would be very much appreciated.thankyou in advance..hallyboys..

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!!

Comment by Guest, posted on Oct 25, 2008My Aquos has the same problem. I'm not sure how I discovered this, but when I lean the TV forward and hit the power button it will turn on every time. If the screen blacks out and I don't lean it forward when I hit the power button, the screen will just remain blank. It is very weird, but at least repeatable.

- Thank you, Guest. That did it. It definitely seems to be a problem with the TV. Tilting it and hitting the power button helped me get the video back.

SOURCE: Sharp Aquos - switches input modes by itself, only when cold.

I believe your TV needs the latest version software upgrade. The current software may have been corrupted.
There is a USB service port on the side of your TV. You can download the software to a USB memory stick at then upgrade your TV from the service port.
If any problems doing this, call 1-800-BE-SHARP and they will run through the procedure.

SOURCE: My Sharpe Aquos TV screen stays black even when switched on!

Call up Sharp, if you are part of the AQUOS Advantage Program, you get FREE in home service along with the repairs for it.

They'll give you a case number, set you up with a technician and BAM!
I called on a Wednesday and got an appt for that Saturday for the technician to come to my house.

I doubted Sharp alot less after that.

It takes about 30 seconds or longer to switch stations. I just purchased it last week. Do not have the manual

If you purchased it last week, does that mean that it's under warranty? If so, contact the shop, they will probable provide you with a new one, cause I've never ever heard of a TV set that takes 30 seconds to switch stations. Ever :-'

Any luck? We bought our tv (same one) in March of last year. It is doing the exact same thing. Time Warner has already came out and switched out the cable box and cables. We have a tv tech coming soon (contracted out from Samsung, of course...) Problem persists...

Bought a Toshiba Regza 37rv635d last week.

I have had the same problem today. I think it might be to do with the master power button on the side, as it seems loose on my tv. Did you ever solve the problem on yours?

I think you are looking at a power board problem. I had the same thing happen to a Vizio and I replaced the power board and it solved the problem. It could also be the input board but most likely the power board.
