Dell 2209WAF still horizontal lines after cap replacement

[mrvectrex]

Hi

I wonder if you guys could help me. I have a Dell 2209WAF Monitor right now and every time I turn it on it works for one or two minutes normally. Then horizontal lines appear mostly at the bottom til the center part. Everything starts to lag i.e. mouse movement is delayed. After plus/minus 30 minutes the monitor has warmed up and it starts to work flawlessly.
I have replaced all of the caps and it is still exactly the same as before. It seems like a very odd issue to me.

What's going on?

Thanks for all your help in advance.

Cheers!

Since it sounds like a thermal problem, I suggest you take a hair dryer and heat up various portions of the logic board to accelerate when you get the normal picture. Once you narrow down the location that's causing the problem, you can perform more focused troubleshooting. It could be a bad cap or solder joint that causing the problem. Also re-seat ALL cables connected to the logic board.
