LCD Monitor Repair - in 5 mins!

This monitor would power on then go back off.

This symptom is caused by a very common problem that has affected most modern computer electronics in the last 10 years. Cheap and faulty capacitors. LCD monitors are no different and you can save yourself hundreds of dollars trying to replace them by simply replacing some of the faulty capacitors inside.

All you need is basic tools, some replacement capacitors and basic soldering skills.

Total retail parts cost for this job was about $6, if you order them in bulk you may be able to pay less than $1!!!!!!!!

This Acer monitor has been in my office for a few years, it died early and was close to end of warranty but was never shipped off due to a lazy employee in the past that waited too long.

on a hunch i tried heating it up w/ a hair dryer that works.. i let it sit for 4 hrs nothing.. i hit it w/ hair dryer less than 5 min it was working tried it the next day didn't let it set at all it worked right away w/ the the heat. why is this??

@cookiemonster31377 There's probably a broken connection somewhere, the expansion from the heat is enough to close the gap.

wonder if u have seen a screen that is really bright,and mostly gray,and colors are pinkish and almost none existant,it was doing the turn off thing for a while i would have to turn it on and off repeaditly for it to come on,then one day it tried to come on doing that trick,but the colors were all messed up that bright gray thing,so i replaced the bad cap,and it does come on now,but the colors are messed up.is there any other parts i should replace u can think of,no other parts look bad

@agdthatguy The last time I saw one go pink it needed a new screen. I would research that model on Google and see if anyone else has the same problem.

Thanks for the video, I'm having the same problem with my Dell 2007WFP

I've stripped it down and removed the various boards. Problem is the caps look totally fine on all of them.

Can the caps be bad, but have no bulge?

If that's the case, I take it my next step should be to remove them one by one and test them?

Thanks again ;)

@DuckmanCycles

The whole varistor is covered in white plastic and i'm having a hard time getting the varistor out. Is it safe to use the soldering gun and melt the white plastic inorder to pull it out? thanks for your reply

[DuckmanCycles]

@Raywithstyle The white plastic is an insulator to stop arcing. Its regular solder underneath.

I have a question. My monitor is viewsonic and some of the capacitors are what believe is weld with white plastics, Can i replace these capacitors with solders or i must find that white plastic?
