    I don't see any loose connections on the board. When I plug it in it makes the clicking and the power light flashes on and off. Also the television stopped working while it was on. Thanks for your help.

Dear tonyb73,
Try to check the relay in your power supply, it might have a loose solder or loose connection at the back of PC board. The sound that you hear when you plug is the relay itself. if your set newer , check for loose connections on pins and other connecting parts of relay. That is located in the power supply section. If nothing happened after resoldering, then replace the relay, probably the contact points is corroded or damaged.Hope this will help...pls. send feedback so we can work together.. Thank you....
Good Luck..

rgrds,
Eriez

TV Wont turn on after lighting storm. I have tried to; unplug and plug back in. Unplug it for 24 hrs. Try different outlets. Look at the build, looks fine.


The TV circuitry is designed to protect from power surges. The fuse on the power supply may be blown, or the power supply itself could have taken a hit. I would try to check the fuse first and then if it turns back on... it did it's job!

Good luck! and let me know what happens!

Not power not picture or sound


If its Dead Dead ,that mean no power is getting past the fuse :> then it needs a fuse
.30 vs 300.00-400.00

Ok there is a way of telling if its posibley
just a fuse . First no blinking lights ,good
no clicking sound from the set when you
try to turn it on .good

now unplug the set for about 30min
the plug it back in slowley if you
see and or hear sparks coming from
the plug , this is normal but bad news
for it being just a fuse , if you dont
see or hear a spark its likley just a
5-8 amp fuse blew inside the set. :>

Hope this was helpful

My TV does not power up when the power button is pressed.


It's sounds like your lamp or backlight has went out, I suggest reading your manual for service info and look online for a local repair shop.

No picture, no sound, power light steady green


First: Check the power outlet. Check it with a good lamp so you know you are getting power to the set.
Secondly: Check the power cord. Wiggle it around the molded ends to make sure it is not open inside the molded portion of the plugs.

Thirdly: If you know for sure the set is getting power and still no indication at all (you should be getting some little light on the front panel; standby indication) then there may be a fuse on the back panel or just inside the back cover (you will have to remove it; after unplugging the power cord) that needs replaced.

Fourthly: After all these checks if you are getting nothing, you may have some failure inside that is very serious. Normally we do not recommend serious repairs to a set over 4 years of age. This is because the set is likely to develop some other problem soon after the repair is made; further, the repairs are getting more expensive day by day while the price of new sets is coming down dramatically. Lastly, the new sets have better picture, longer lasting circuits and better features.

Hope this is a good solution for you.

thanks for your questions.

It makes a clicking sound when i press the power button but dosent turn on


Good Day, nhl1fan;
The TV is getting power and the main fuse is okay. Try unplugging the TV from the outlet for 3 to 5 minutes then plug back in A/C outlet.
If no fix your TV has something inside that is shorted (drawing too much current), then call an authorized Service Center to give an estimate before proceeding with the repair.
Good Luck, big IRISH.

My tv did not come back on after a power cut could it be the fuse


Good Day;
After a power outage it is best to 'reboot' the TV. Unplug the TV for 4-5 minutes from a/c outlet, wait, plug back in. Did not work?
It could be the main fuse, it will be located near the a/c cord on the TV's board. CATION!! After removing back of unit make sure the TV is unplugged from the a/c outlet and the fuse will be a glass fuse, ensure that it the correct value eg; 5 amp 250v.
Good Luck and Careful, Big Irish.
