Not sure what issue is: it turns on then quickly off?

short in power supply or more commonly in the high voltage area---bad solder connections (age of set does not matter) are also very common.

Sharp TV struck by lighting replaced all boards got standby light could the led lights be fried and keeping TV from powering up

There is a row of LED lights that are called the "Backlight" and if there is just one LED burned out, the cost of replacing the back light strip will either meet or exceed the cost of the TV. I have worked on several TVs and they ALL had the same issue.

You might luck out and find a repair shop in your town\city that knows about this issue and can go in and replace that LED strip( it carries 25+LEDs in a single row) or just replace the burned out LED(s) without costing you more than what you paid for the TV.

Hope this helps.

How do I turn off standby mode on a Sony XBR television?

Here's how, but it will cost you in life expectancy of your TV set. Standby costs a bit of energy but prevents cold components getting a sharp smack of power surge and also lessens amount of heating components are subjected to during start up.

It's sharp 52 inch lcd tv. Model is 52SB55U. I could not turn on the tv. There is no backlight, and only the power and opc indicator are blinking. I tried the factory reset, it didnt work. It could be...


Check the power supply; look for bad caps with leaking/bulging tops, check to see if you have standby +5vdc at the power supply connector, the front red indicator will not be on if you do not have this +5vdc standby voltage due to shorted out power transistor and zener diode...if otherwise, Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like, to buy a whole refurbish power supply board for the replacement.

I hope this will help in solving the problem....

Sharp tv 20V-L80M standby only

If not power up even by remote control then check the the H-out transistor for short, open fusible resistor in line with the b+. This is the most common fault of your problem.
Needs a technician to isolate the problem.

Thanks for using fixya.

Sharp aquos won't turn on

Any indicator lights on, if it is then you only have the standby 5v circuit working, you will need to have the power supply check out first, that is a starting point.

Sharp 34" TV

Why shouldn't it be worth fixing? It's only 4 years old, my own TV is 15yo, I fixed it twice but it's still kick'n! You have a problem in the power supply, do you have electronic's know how? And test equipment? Soldering equipment? If so we could walk you through it, If not A repair man should only cost 80 to 100 to fix it.
