Monitor flickers on start up after shut down


The symptoms you have are very common on this model. The capacitors in the power supply are beginning to fail and as this happens they can not filter the power correctly and you get the flickering until the unit stabilizes. As time go by the issue will get worse until the unit fully dies. The repair is very easy, you will just need to replace 6 capacitors on the power supply board. Here is a link to additional information on repairing this model.

I hope this helps,

This kind of problem will require an in-depth troubleshooting to narrow down the problem. We need to find out if the backlights are flickering, you need to look at the back side of the LCD panel to see if the backlights is flickering, or the T-CON board may be flickering on and off.
Are you going to DIY repair?
Please read my guide first then you can decide:

Capacitors kit: he can make you a set of caps.
Or, just make sure to use caps with low ESR, 105c, high ripple current and long life rating such as PANASONIC FM or FC series.

A few months ago my LG Flatron L1900R monitor started flickering when I boot up my computer. It has become worse, to the point where it now flickers constantly.

From the information desribed, this means that your CRT monitor is going dead. Unfortuntly, there is no way to stop the flickering unless the monitor was replaced. I hope this has helped

It sounds like the video processor is getting noisy. Maybe small capacitors not decoupling noise from other stages but whether you would find anyone willing to have a go at repairing it is another matter. Maybe worth trying another power supply perhaps, but I wouldn't hold your breath.
Sorry but not an easy fix if it isn't a lead or connection problem and I don't think it would be if it is a digital set.

I would suggest to call Samsung to get the Plasma repair under manufacturers warranty. The flickering will not go away until the hardware failure is corrected.
Good Luck.
