If the TV goes off completely, then is usually a faulty power board.

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 26mf231 Magnavox 26 inch tv. The screen on the tv just flashes over and over. Never powers up. I took out the power board and all the capacitors look good. Thanks in advance


How many times this standby/power light blinks at one time switch ON? Count it carefully. These blinks are fault indication, and known as blinking codes. From the number of blinks occur at one time switch ON; you can get an idea about the faulty circuit stage inside the TV. This will make repair easy.

The blue standby light on my bush 19" lcd tv stays on all the time but i get no picture or sound can you help.


The II2 Bus has the fault. It detects some malfunction from other circuit boards. Your TV need a through checkup. Contact any experienced service technician, as the work is a very skilled one, and not a user reparable.

Hi! I have a 32" LCD led backlit bush tv (not sure


Yes, all the issues point to a problem in the standby power supply which runs 7/24 if the set is plugged into wall power--get it taken care of under warranty before it really fails bad.

Polaroid 26inch lcd tvred standby light on but power wont turn on. I've unplugged the tv, changed the batteries in the remote. The tv stays with the red standby light only.


You need to open it up and checking the voltages in the power supply sections, you should have 5v (for logic circuits), 12v for sound, 24v for backlight inverter circuits. Look for bad caps with bulging tops in power supply also.
