Using a Philips driver remove the 18 screws from the rear panel.

Gently lift the rear cover off the TV. You may need to wiggle the cover a little however there are no clips holding the cover on so it should come off easily if you have fully unscrewed all 18 screws.

would it be possible to replace the 2200uF capacitors with a larger size? this issue has occurred already on this TV and again on another of the same model. Thanks.
Higher voltage rated and better quality caps are what you need, don't change the value of teh capacitor though.

Hello, I have the blinking red lights when I try to turn on my Samsung lcd tv. I checked the capacitors and they seem to be fine except a smaller 16v 12mm capacitor is slightly bulging(not broken or leaking yet). Would that be enough to cause this? And should I just replace it?
Thank you!
