Question about Sharp Aquos Televison & Video

Open Question

I have a Sharp AQUOS Quattron ++ 80" that just stopped working and I can not get it to turn on. Model LC-80UQ17U

TV cuts on and off then blinks 3 times slow and 1 time fast. "Flash Light Test" shows no image or menu on screen. No sound that i know of. LEDs not lighting up. This condition came on suddenly with no pre-cursor or warning. One day the TV worked the next it did not. It IS on a surge protector. I have already replace the Power Board and the T-Con board with no luck. I really don't want to spend another $100 on the Main Board if it isn't the problem. Any info would be greatly appreciated.

SOURCE: If a warning light indicates the CPU is not functioning, does that mean I have to get a new processor?

Yes! judging by all the cascade break downs, I would suggest replacing the motherboard, HP has a history with motherboard issues.

Quality is in the eye of the beholder. Female have 2 times the color receptors in their eyes so they tend to be more particular about colors. Adults over the age of 19 begin to yellow their eye lens until brightness and contrast become a major issue as young as 40. And critics don't mind offering their opinions especially on TV settings. The easiest way to gain their incite is to google the "manufacturers name" followed by the "model number" and the word "review". Good luck.

Sharp aquos lc-46le810un won't power on, psu diode zener and fuse blows..cause?

Unhook the PSU from everything that you can and turn it on, see if it blows anything out. If it does not then you are looking at a non PSU problem. If it does then it is psu. You need to get the schematics for this set if you can.
