Dell E228WFP - Random Turn Off

[Ritalin]

So I got one of these monitors free of craigslist, and at first it wouldn't turn on at all. Had a few 'ing caps. Replaced them all and it started right up and used it for about a week. Now it's starting to do the well known random turn off. Apparently there's a resistor that's underrated that's turning the monitor off.

Here is the thread regarding the resistor. CLICK HERE!!!!

Any thoughts on if I should just do what this thread says, or go through the whole trouble shooting process?

The resistor change/addition described,says it can cause even more problems.Myself and others have changed one of the smd caps,as that seems to be a cause of this sort of problem on a number of these monitors.it may be C803,but if you read all the threads on these you will indentify it.

I re-read the whole thing and you're right, not digging the half of a side going dim. But the C803 is such a small cap, I don't know if I'm capable of fixing something that small.

If you check the threads on this, you will see in photos how I fixed a much larger replacement cap.

I searched "E228WFP" on this forum before posting and I didn't find any?

So what is the part that I need to buy, having a hard time finding it. Looking to purchase it from Digikey or Newark.

Post 52, tells you value of cap 0.1uF, at 50VDC

I saw that, but as far as lead spacing, tolerance, etc... anything else I need to worry about?

Nothing special,it was a simple disc cap, taken from an old Benq board.one of the posts shows how it was positioned etc.

Crap, I'll have to see if I have any old boards laying around. Don't want to pay $10 for one + shipping.

Re: Dell E228WFP - Random Turn Off

Finally decided to order parts and they're here! Time to try to change out these little buggers.
