Tv wont tyurn on and the DISC light is flashing 3 times

Hello,

The power supply board is 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 will help in solving the problem, and do take care in handling the television because it contain high voltage.
Thanks

When a TV won't turn on, you are obviously looking at a power supply issue.

If you aren't comfortable with electronics, get a hold of a friend who is or go to a service center.

However, if you remove the back cover (be sure to double-check for screws and be gentle), you can easily see which PCB the power cord goes to. Check for bulging capacitors. That's a very common culprit. They are the little cylinders. If you know how to solder it's a simple task. Just buy new caps and put them in. That's the cheapest way.
If you're lacking on the soldering skills, you'll have to buy a new power PCB. Get the part number off of the board and search on ShopJimmy.com or eBay.
I'd be glad to help you out via e-mail if you like.
