Flashing red light

if you have guaranteed power to the set it is likely you are having an issue with the power board. You will have to unplug it and remove the back of the set. Then check the power board for any blown fuses or other components. You do want to post pictures of your boards with your question so we can try and assist you further with that. For that use this guide The attached image should show the fuse on your power board. Check for continuity and see if you get power to that, once it is checked. Unplug your set to check it for continuity. Then plug it in and use your meter to check for power.

On old projection TV's that wont turn on could be a bunch of things.
So if you plug your tv in and you not only hear nothing but also see nothing aka flashing light or anything of that sort. You might want to look at your power supply board. This is high voltage and i mean it, unplug your TV for about 3 days before looking into the back. The power supply board is the one that the power cord goes too from the wall. I would look for any visual damage such as blown capacitors or fuses. If your not familiar with electronics, capacitors are the cylinder looking things that stick out of the board with silver caps. If those caps are bend upward at all, they are bad. Here is an example of bad capacitors.

If you are getting signs of life from it I could be something else. If you give some more info i will glaldly tell you where to go from there

if you look at the capacitors on the boards you will find several of them that are domed or blown, these are the most likely cause of the problem. you can find replacements for any capacitor online at electronics supply stores, like radio shack but don't try them they don't supply enough different types. you can also find examples of blown capacitors by doing a search for "blown capacitor image" on any web search. unsoldering these bad caps and replacing them with identical values like 220uf (microfarradys) and say 25 v(volts). these caps have a + side and a - side the caps are marked and so is the board. hope this helps.

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

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 , startingthe flashing light.


If you are in situation one, then theTV 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.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


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.
