Thanks for yor effort helping me.
I measured resistance in transformers secondaries (onboard) and they are similar. 1.32 and 1.35. They are ok? What else to check?Leave a comment:

Ok!
I conected videoboard and power board (without lamps and panel) video cable to pc and turn on pc and monitor and measured On/Off 2.37v, A-Dim 0.01v.
Is that ok?Last edited by rico_st; 06-10-2011, 07:02 AM.Leave a comment:

Hi!
My knowledge about electronic isn't too good but i measured it on the back of the board. On/OFF 0v, A-dim 0v, 5v and 13 are ok.
(i measured it without connected videoboard?)
Here are pics of the back....Last edited by rico_st; 06-09-2011, 11:18 PM.Leave a comment:

Re: Samsung 930b LCD cold start problem (inverter?)
Hi!
Problem is that backlights arent working at all.Power light is on. I replaced 3 bad CapXon 820uF 25v caps with 1000uF 35v and others 2x100uF16v,1x330uF 16v, 1x10uF 63v, 1x47uF 63v. I replaced them with new "JAMICON" caps. Replaced picofuse with litle wire.You can see picture but still no backlight. Where else to look?
Thanks!Leave a comment:
