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.

If the red light stays on and the tv does not react to any input from buttons or remote... the problem is one 7 pins integrated circuit on the upper side of the power board .the ic is situated on the right side of the power socket .It costs about 2$ and can be replaced by someone with mimimal electronics skills and a 30w solder iron .

I have a Sharp LCD TV Model # LC 32SB220U. When you turn the power on, within a minute or two, it clicks off. I have tried everything in the instructions to troubleshoot the problem. I also reset to...


Check the high voltage circuit on the board that has the 120 volts input. The high voltage should be close to 400 volts - nothing less than 390 volts. The capacitor is failing to hold the voltage and needs to be replaced.

My Sharp Aquos LCD TV LC-40C37U will not power up. The green power lamp at the bottom right is blinking. We had a power surge last night, I even measured 180V on the power outlet. Is my TV now damaged?


Good day sir/maam, chances are, yes or no, yes, the surge do has the ability to damage your TV, but no, modern TVs are autovolt (it can work from 90v-240v) so check the manual or back panel to confirm. The most deadly part of the surge is it can hit more than 500v at a split of a second, damaging your TV's switching power supply. The TV's power supply is bad. it cannot produce the proper voltage to power your TV. thats why its on standby. Bring it to your dealer for proper advice on the status of your TV.
