Re: Smasung SyncMaster 913N Monitor wouldnot display images

Hi,

I've got the same Problem (resolution not set to optimum/no signalin a Samsung 910TM.
The current going out of the very good looking inverter Board between 1(red) Plus and the other pins are 2; 0V, 3;12,5V, 4;12,5V, 5;12,5V, 6; 7,5V, 7V; 7,5V, 8; 12,5V, 9V.
I am not sure which pin 5 and 6 you guys are talking of and I can't find it in the respective part of the post. Can anyone tel me if the pins are suposed to be the ones on the SE7888/SE7888 Chips?

Cheers, canadan

I do have a soldering Iron, but it is let's say quite one the brink of destruction... It was a fairly cheap one and I can't get replacement tips. To replace the transistors I had to use up quite an exxesive amount of sandpaper on it. But I will probably try to replace the fuse anyway.

Hi,
I read that reference, to. But I thought that the respective fuse is pf 801 which I have tested and found to be OK. There is however a glass fuse near the power input. I'll check that one.

Re: Benq Q7T4 FP71G

Hi,

I have the same Problem as FreeGeekVan. So far I replaced the (obviously blown) c712 as well as the c707, c708 and c709 (just in case). I furthermore put in an new Q805 (shortcircuited with IRFU 9024N and replaced al sc5707 with sc5707. I tested the fuse PF 801 and a current can run through. The symptom of a white screen with running backlight has not changed. Does anybody have an idea how to fix my Q7T4? I can not test capacitators so I do not know which other ons to replace. Furthermore my standart electronics dealer (in Germany) does not...
