Re: Dell 2407WFPb Monitor - Bad Cap



I think there was a post earlier here where a bloke had deemed it faulty as a connected cap was giving incorrect readings when on the board, but checked ok individually, though I may have mixed this up with another IC anyway



Makes sense - I've got 3 of these monitors, so was probably gonna order some extars anyway. On this topic, is there a consensus on which component or components actually trigger this fault? I wouldn't mind replacing these on the other two monitors, since they're of about the...

Re: Dell 2407WFPb Monitor - Bad Cap

So I've confirmed the following are dead:

C605 - 120uf 450V 105C
F601 - 4A, 20mm, antisurge ceramic fuse (T4A H)
Q651 - STP10NK60ZFP, Zener protected N-channel MOSFET, TO-220, FEC code 993-551
ZD601 - 15V 0.5W Zener diode
R670 - 0.22 ohm

Is R670 a 1/2W?

IC651 - L6561D - physically appears ok, my multi doesn't have a capacitance check, are there any other test for this one?

OK Cheers. I'll set aside some time to read all the way through ...

Re: Dell 2407WFPb Monitor - Bad Cap

Sorry if this has already been covered, I scanned through this thread and did some googlin, but it's hard to absorb information when post #9 in a massive thread is a picture perfect image of my leaking cap, but with different markings

I'm an Aussie (so our sparks come out at 240V) and one of my three aged but still fantastic 2407WFP's turned itself off while in standby the other night and now refuses to power on.

Here's the only obvious sign of damage (from comments in this thread I see there may be a lot of caps...
