Hello,

I work at GM Antwerp, Belgium, and we have 9 defective V700 compaq monitors, all with the same fault : I connect them with a pattern generator, power them up, and they all have the green led lighting, no fuses blown, there is no high tension, the glowing circuit of the tube lights.
Inside is a power switch IC , type KA2S0880, at the Vcc pin(pin 3) I measure 13 volts dc, but at the secundary side of the chopper transformer, I measure no DC values...
The monitors all got defective after power switching on the net.
Can anyone give me some advice ,or can anyone upload the schematic diagram?
Many thanks in advance !!! Smile
Oh yes, in two monitors I changed the LOPTR,without any result.

Hello,
I found the schematic diagram & manual myself on the internet, 59 pages in pdf format, so my previous question is no longer current.
thanks ! Laughing
If anyone needs it... Wink

search for "schematic diagram Daewoo CMC-710 b,the main circuits are useful, but de component numbers are different!
I found following defective components : FAT/LOPTR transformer, IC KA2S0880(power switch) and horizontal output transistor.
