    I have tried what you said bout trying diffrent power oulets and holding down on button and yesiget the flashing and a little sound for a second. . Have checked loose connestions . Cleaned it before I worked on it. I just noticed the back part of the circuit board is not flat on the bracket. Would this hurt anything ????

    The circuit board is not sitting flat . I ask you if this made a difference.? The back is not locked in. I can reset and lock in if this will make a diffrence.

Hi!

There is either a loose wire or loose connection on circuit board i.e. 'Power Circuitry' problem within the unit. There may also an intermittant component, or a bad connection on the printed circuit board. Switch off the TV, unplug it from the main power supply switch from the power socket and then try a different power socket. Do it two to three times. Also try this as well: press and hold the pwr button for several seconds, you'll get one flash, followed by nine flashes. Now clear the circut board with compressed air and make sure all the connections are secure.

Rremove all the paneling on the back and use compressed air to blow out all dust, and check that there is no burns, popped diods and fine circut board .

Please do accept this solution and revert for further assistance.

Thanks

    Hi



    Thanks for your reply. As you said the circuit board is flat so you need to get it repaired/replaced as there is either a loose wire or loose connection on circuit board i.e. 'Power Circuitry' problem within the unit.

    Thanks

Green light comes on 3 times and clicks and then wont come on.


replace the flyback, thats usually what is defective when the led will come on 3 times then go out. You need flyback 259296 which is very easy to replace. You can get one at the following link with free step by step instructions with pictures. Read the reviews on the flyback. Heres the link.
