Sony Triniton not powering on

Every set has a standby power supply that runs 7/24 when set is plugged in---it means in this case a main power board or something associated with that is not working, Set is not making it from just standby to full on.

Hello,

Your power supply board is dead, do you know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

I hope this will help in solving the problem..

Yes! I find in most cases it is due to bad capacitors in the power supply and high voltage area of the set, sometimes the capacitors develop a bulge at the top which indicates they are open.

Is it blinking a code? * * * * * * * * * * * * This would be a 4 flash. Count them and post the flash code.

Could be a fault in the powersupplym could be a flyback issue it will need to be evauluated to see what is the cause now most shops will tell you what it is without charge that way you can decide to repair it or replace it I am telling you it could be a power supply issue or flyback I will need to look to rule it out but at least you know what the problem could be and determine the cost of repair. please do click the end session to your right,

if u r the macanic of TV then check the entire power supply n standby circuit

This means one of three things, either the lamp is bad on your tv, the ballast that powers the lamp is bad or the safety switch for the lamp door is not depressed or it has come un-plugged. It could also mean the power supply or fuse on the power board is blown. I am assuming this is a DLP tv, and if so, it is fairly easy to fix it or find parts for it online. If you are slightly mechanically inclined, want to save money and dont mind paying attention to detail then you can fix it yourself. If you need help dont hesitate to ask.

the main problem of your tv set is the main power or what u call the regulator.the red light blinking it means your tv set is on standby mode.

the 9 blink code is caused by a bad diode on the pc board. The zero crossing detect circuit is not allowing the power supply to come on .

Hiii....

Loks like trouble in A board ( referee to blinking code ),the +13v is not supplied,so the power supply become stopped,the tv will back to standbay mode ?! check the ic561 : STV9379A ....

Hope can help you...

Thank's
