I have had my PC for a while and the monitor came with it. But recently the Monitor Keeps on flashing with different brightness. In fact it is doing it right now. The brightness settings stay the same but for some reason the brightness level goes from up to down very quickly. I would think probally inline with the refresh rate maybe a little slower. I have had the Electricity supply checked and the current from the mains is coming as it should. I have got a Surge protector and a device which levels out the current from the mains but still i have this problem. I also have a TV which chages the colour of the screen to black. for example i am watching a film and then the brightness of the screen begins to reduce until it is totally black. I think that a part has gone on that. If anyone knows of the part the needs replacing could you please tell me.

most often just a bad connection at the signal plug, but can be all sorts of things.

No chance, you need to do some fault finding to find the fault.

I have tried. I tried changing the settings from the Focus Unit. When i chage the level of current going into the screen it seems to make it worse. so i have reduce that. It has made the pciture darker and it takes a little longer before it starts changing the brightness. I reduce the focus as well and all that does i prolong the effects. I have looked at the circuit board there are obvious signs of a blown up part. I have checked the current on the board in different areas it looks OK. There is a Switch on the board it have no label on it so i didn't mess with it but it might help if anyone knew what is the job of switches in TVs. I looks like the sort of switch you would find on a toy. I will try and get you a picture to help
I can't put pictures here but here is the link.

This on is right angled but the one on the board is not.
There are ways to die inside monitors, so as you dont know what youre doing I'd suggest leaving it alone. Sometimes thre are more important issues than a dim or flickery picture.
