Tv wont turn on, Power light on tv wont turn on

July 19, 2012

Alot of people recycle old LCD and LED t.v’s, which is a really good thing. Especially if you are me.

When you have a TV and it wont power on, your problem could be really simple…..and super cheap to fix. I recommend doing the following.

Please dont be afraid to do this, as long as the TV is unplugged, and you are a little careful, you shouldnt have any worries.

1. Unplug the TV and flip it onto its front side.

2. Start removing all of the screws found on the backside.

3. Before pulling up on the back, be sure all the screws are out. If you start to separate the back from the front plate and it doesnt seem like it wants to go, double check the screws and BE SURE THEY ARE ALL OUT before you start giving it some more force.

4.  Once inside of the TV, you should more than likely see two main components. The one you want to inspect is the one that resembles a motherboard.

5. Look for capacitors that are bulged or blown. They should be level on the top, if you see a slight rise they are probably bad.

6. Now for some fun. Remove the screws holding in the board and pull the board out.

7. Get a soldering iron and put pressure on the solder that is holding the capacitor in. This is a little tricky at times, but eventually with some force and enough heat you can wiggle it free.

8. Once you have removed the bad capacitors look on the side of them for a size and rating (generally speaking you can get them online, but i always luck out and can pull them out of PC power supplys i dont use anymore)

9. Resolder in the new capacitors, and put everything else back together. Try to turn on the TV and hope it works.

10. If this doesnt work, look online for a new Main board, or a power supply. You could always buy both and return the one you dont need. These boards are generally speaking inexpensive, making it worth it in most cases.

 

**PLEASE BE CAREFUL WHEN DOING THIS. YOU CAN HURT YOURSELF. IF YOU DO NOT KNOW WHAT YOU ARE DOING DO NOT TOUCH IT. I AM NOT RESPONSIBLE FOR ANYTHING YOU DO WITH YOUR TV PER THIS ARTICLE.

Good luck and as always….ENJOY.

  1. I know this is very old, but there should really be a disclaimer on how dangerous power supplies can be
