Can't turn on tv

Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Someone is going to have to go inside and check voltages and other things --no brand or model is indicated here so this is as much as I can suggest.

Hello,

there are several things that could keep a set from coming out of standby mode. It could be a defective power supply or a defective main board. You will need to have the set diagnosed to see why and which board is causing the problem.

Powering up do you hear the relay click then you may see the display flash (not necessarily), but then the TV clicks back into standby mode. If so there is a component failure.
will need diagnosis by a repair shop. Too many different components it could be for me to guess. but
the common repair kit containes1 fuse (F302), 1 diode (D304), the power resistors (R927 and R929 for the board revisions with these two resistors) and the IC301 voltage regulator IC.

If the standby light is on and it does not respond, it is most likely to be a problem with the power supply . First try this, unplug and leave the set like that for a few hours. Then plug it back in to see if the tv attempts to turn on when you try to power it up. See if you hear a "click" even if it goes back to standby. Let me know what you found so that I can help you test the power supply board to confirm, if necessary.

Hello,

Your power supply board is not yet dead, u 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 help in solving the problem....

There is a Sony S3000 protect blinks table:

The problem with your Sony. This is a common problem with these Sony sets.

1. How many times does the light blink? Is it consistent and continuous?
2. Does anything happen to the picture itself, or does the set just turn off?

Answer that and I can help you.
