Hello=)
I'm new here so please bear with me.
I'm a newbie in this field....
I have googled alot and found a couple of threads here but decided to make one thread of my own.
I have one hp 1940 (Benq 48.L1G02.A00) that when plugged to power starts flicker rather rapidly and just keeps doing that. To mention not connected to PC. The power led is on.
It's not originally my screen so I can't really say anymore in the symtoms department and I removed the power board from the inside now. Nothing really seems to be blown or damaged, no bulging of capacitators. Is it the usual C5707 transistor problem?
For the hp 1955 (Benq 48.L1A02.A00) the monitor was just totaly dead.
So I opened it and removed the power board. So I found out that one of the three pins on the power cable connector was blown. If you look at the "green" side its the left pin. the center pin was loose and the right pin had cracked solder. So I resoledered it. I think I did I decent job on that but it didn't help at all. The power led didn't go on. also here is no bulging on capacitators or something similar. What do you think, could it be both the C5707 transistors and the picofuse maybe?
I have a digital multimeter with a diod check. Is there more meters that would be good to get? Would the multimeter be enough? Also what way or tools would be the best to remove soldered objects?
thanks!
