With the model which is not indicated here Google that for 3 blinks to know what the error code means.

This tv have a power supply board is the causes and the problems.Ur tv power supply board finally gave out and not supply the right voltages to the tv system anymore.That the board,where the tv power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Either give me a yahoo or note if light on front of set blinks--count the blinks if it does.

Time to get a new TV. I have similar problem. In my case, the set turns off, LED blinking green for about a minute or 2, then the set will turn on by itself. Something the LED started to blink yellow after blinking green and then shuts off. I can turn it back on. This happens 3 or 4 times in an hour. After that, the TV stays on for as many hours as I want until I shut it off.
And then the problem repeats everytime I turn it on from a cold start.
I have my eyes on the 50 inch Plasma from Panasonic. Bestbuy has one for 999.99.

Power green LED light should come on, CHG green LED light should also come on showing the battery is being charged. Leave your unit in Suspend mode while charging it, DO NOT turn it completely off as "Shutting Down.." because it will not charge your battery.

I just purchased an almost new Archos 5 on eBay recently, and the first day I had it, happened to me that I left the unit off and charging on the Mini Dock with external AC power supply, after 13-14 hours the CHG light still wasn't blinking. Then I though maybe I have to leave the unit in Suspend mode rather than completely off, which I did, and in a matter of 3 hours it fully charged the battery.

Again, do not shut down completely the unit, leave it on Suspended mode, or even on, and connected it to your mini dock, after a while the screen will go blank the unit will go into Suspended mode by itself, and after 3 hours on external power supply or 8 hours via USB on PC should be completely charged and your CHG light should be blinking, indicating the battery is charged.

I hope this helped.

The 2 blink error is a temperature error and the 6 blink error is a thermal fuse error. You may need to unplug the set and get you a can of canned air, take off the back lower cover and blow out all of the fans inside the set.

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.

Start by replacing the bulb. If thats a no go, check the ballast. Its a small circuit board directly underneath the bulb housing and is replaceable through the bulb panel. If those two don't work, comment back and I'll walk you through more 'in depth' repairs.

The TV's power supply capacitors probably went bad.

Check with a mobile tv repair co. to see if it is worth fixing.
