1 check for short on HOT (horizonal output transistor) or bad flyback transformer. 2 check the AC voltage on the relay switching side. if AC voltage is not present on both pins and the relay is engaged replace the relay.3 check for shorts on voltage regulators you will need a schematic for this.

Aside from checking the fuses it likely will require a technician or a shop to examine the set to see what is wrong and what needs to be replaced.

Sounds like a power supply issue but that would need to be checked.

Good morning, My tv is only 3 1/2 years old. It just stop working, I changed the batteries in the remote and still won t work, I will try to turn it on, it comes on for about 2 seconds then goes off...


Hi, there must be something wrong in the power supply circuit, usually because of bad or off value components, if the TV actually gets a picture and cutts off, the power supply could be the circuit to suspect, if the tv does not give a picture, it only does the click and the power light turns on but nothing else happens, there could be something else wrong besides the power supply circuit.

take your tv to a repairing shop and let your technician check the power supply section is not producing an ht to trigger the line transformer, in turn various voltages will be produced, which will open up your tv.

No Power to TV


There is no reset button on these new sets,your set has complete power problem since you have no lights no clicks,this might have happen because of lightning or power surge,either one creates a lot of damage,if you are familiar with tv service you can check the main fuse,he should be close to where the power cord comes in,if you find the fuse blown it needs to be replaced with an exact replacement for AMPS rating and VOLTS rating as well as size,if the fuse is blown black we might have more problems ahead in the circuit and it will blow up again as sonn as you plug the tv back in,if it blows again it will need a more involved repair,the problem could be in the primary side of the power supply,if you are not too familiar you should seek the help of a servicer a least for an estimate but if you suspect power surge or lighting damage dont invest any more on this set and get a new one.
