 |
|
I'm looking for some help with a Viewsonic VP230mb flat panel. It seems that i have no DC to any of the boards. ALL HAVE NO POWER, but when I check zd5 to ground, I get +42 volts. When I check zd4 and zd3 to ground, I have +12 volts when unit is plugged in to AC line, but this slowly fades to less than 0.5 volts in a matter of ten seconds. Power switch has no effect. Can somebody please help me on where to look (is ocelator bad?, power transistir bad?, or not in the power supply?)
Thank you for your help. |
