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.

I have a sharp aquos lc-37d44u and I have the blinking green power light problem I replaced the backlight inverter board still nothing and the only thing i.think it could be is the lamps but Don't no


Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. Check all the CCFL lamps for darkened ends. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

If my Sharp Aquos 37in LC-40C37U tv needs to be reset how would I do that? Not getting any power, only a green blinking light. The power supply board checked out ok.


Blinking light is an error code. Count the blinks before they repeat. Check your manual in the troubleshooting section. If you can't find it, contact a Sharp service center or try and get a service manual. Reset info is also in the user manual but you can't do it if your set doesn't power up. Are you sure about the power board?

Blinking led


Free diagrams unlikely to be available take the board's out and check for blown capacitors following good antistatic procedures and decide from there
Or find a good independent repair specialist to do the work and set your self a budget
My sharp aquos stopped working with a blinking power light £2000 was the repair quote for a new board and LCD panel for a £699 TV after they tried the capacitor replacement

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.
