Re: Samsung Syncmaster 245 B+ not working

Hi Every,

I measured now.

On the 5,4V pin I have 0.00
On the 24V+ pin I have 0.00

The biggest capacitor in the middle with 450V 82uf have 323V

All other capacitors I had changed btw not the biggest one.
Any suggestions?

Re: Samsung Syncmaster 245 B+ not working

Hi,

after I waited a long time and no one give's me an direction how i can remove the yellow/brounish glue I try it self with ISO PROPANOL Alcohohl, Toothbrush and an little Clockworkscrewdriver. I hope i damaged my PCB not so many as it is.

It takes about 2 hours and I use an magnifying glass. Look at the attached photos. It looks horrible but PCB Board is not so damaged. Today my new Multimeter will arrives to me and I can look closer and can measure.

Hope now my work was not too bad. ...
