Re: Samsung 192n
Yes I have it open, someone has worked on it before. It has mixed CapXon caps, on the 12v it has (two) 1000uf 25v and (one) 470uf 25v..On the 5v it has (two) 2200uf @ 25v and (one) 470uf @ 25v..All 12v are in parallel , same with the 5v.

Re: Dell E172fpb
This may help you guy's cutting up your case. Mount the mje3055 on the back side, just form the leads and solder in and it lay flat on the board has plenty
of clearance....Leave a comment:

Re: E173fpf
Well seems i have all the required signals needed except the output from U1. I have the signal from pin 52 of the LCD Controller going to the chip U1, but it is being driven to a high level by pin 4 of the U1. Yes i have a image on the screen..I still would like the chip number or what it is.

Re: E173fpf
Originally the monitor wouldn't turn on i changed U805 (smt) pwm controller, that fixed the turn on problem. Now the problem is i only get a momentary flash of the ccfl's. I have a enable clock signal going to (U1) on the inverter part of the board but the output of it (U1) is just one short pulse. I'm sending a photo with the chip noted on it and the writing on it.Leave a comment:
