Re: No power (blackscreen) with MD3021PH -> AI-0088 the reason?

Hi all!

I hope You people can help me a little more.

I have replaced all four mosfets and the monitor works now but with problems. Thing is that whole picture is shifted to the right for about 4 - 5 cm. But not in all places, in some places is like 2cm an in others 5 cm. But how he got hotter (work for a while) it got more uniform in all places, 4 cm shift. I can post a picture of it if it would help. Second thing is that there is a few horizontal lines across bottom and top of the screen....

Thank you for your hint. I did change all the capacitors and fets are ordered.
Just one question. Two capacitors near transformers are 150uF 25V, but i could only find 220uF 25V. Do you think this could be a problem?...

Mr. knurz.
Did you manage to repair the monitor? I have a Xerox XA7-17i and same power supply board and apparently the same problem. U102 & U104 shorted, monitor is dead.

Please reply with your solution if you have repaired it.

Thanks in advance, Danijel.
