LCD won't start up when cold

[ShaneDale]

To get it started I would have to use a blow dryer and heat the back of it up to get it going. I have already done some research and I believe its due to a bad capacitor. Anyway I opened it up and I think I found the bad capacitor. I would like a second opinion on it and any other bad electronics that need replaced on the board. Thanks!

I cant see very well but check the bottom two electrolytic capacitors on the 3rd picture for bulging. Also check the blue ceramic capacitors for leakage ( the white paste is glue ignore it). If you have any solder equipment try replacing the capacitor and see if it makes any difference. The capacitors are pretty cheap on ebay, i know i got some for my monitor i believe 10 for $1.50. Now it is not a guarantee fix but at least you can cross capacitor failure off the list.

Didn't even notice the bottom two were bulging until I looked closer. Good catch! I'm definitely going to replace them myself... Umm I have never replaced capacitors before. Is there anything I need to know about discharging them or how I should go about changing them?

Yea its always good to discharging a capacitor that has been used before. But if the capacitor is brand new there is no need for discharging it.You can do it by shorting out the two wires. Usually the easiest way is to use a screw driver, since the handle is plastic it wont conduct electricity to you. If the capacitor had any electricity left it will make the same noise a static electricity discharge does, so a kind of  like a crackle noise.

I replaced the 3 capacitors and if fixed the screen! Only costed me $4 and about an hour of my time. Thank you for the help eric95204!
