What is the common cost of sharp tv when quecly tornoff

This sounds like a power board issue, if you unhook all boards and power the power supply up does your standby voltage seem steady?

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.

Dear Anonymous,
The main Board is also defective!

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.

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.

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.

I have same problem, In Caribean and repairs and new TVs are extra costly. Bringing power supply back with me to USA to see if I can buy a new one.

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.
