Hey, I Accidentily shorted out part of my power supply on my NEC 1545v LCD monitor.... I found that 2 of the power resisters, where I shorted it out, are burnt and have near infinite resistance now... the bands on them both indicate a resistance of 1.3 ohms...
I am going to try to replace these to resisters to see if it fixes the board, but in the event that this does not work... I have to wait until monday for the local electronic parts store to be open... I was wondering if anyone could tell me what the voltages/specs are for the wires that go from the power supply board to that other board that the VGA plug goes into...
Thanx

Am I the only one here with an NEC 1545 or similar LCD? I would really appreciate it if someone here would be able to test the voltages coming out. I did find out the voltages of the wires going to the backlight, which are +5, gnd, +5, gnd, ?... I can plug in fans here that are for computers and they work great. The colors are exactly the same of this bundle of wires as the one I do not know the voltages of, but it would be really nice if someone could confirm the voltages for me. Just a quick voltmeter reading.... please?!
Thanx a lot
Thanx a lot
Feel like a tarp bieng the only one to post here...
But I really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, really, need those voltages. I replaced the two power resistors that had obviously blown, but it is still not working. I have traced the path on the back of the board and descovered that:
to LCD to back light
first black = first black
grey = brown
brown = grey
2nd black = first black
3rd black = first black
1st red = 2 resistors -> 1st/2nd red
2nd red = 2 resistors -> 1st/2nd red
the only voltages I need are the brown, grey and red going to the LCD controller board. I will forever be in debt to who ever can give me these values. If I can get these voltages I will need to pay... nothing! I have power supplies all over the place that will probobly supply the right voltage... if no one can help me, I have to shell out another $250 for one of these things
Please, please, please, someone help me out here... 3 volt readings
Thanx a ton

hey dwiel look at the nec lcd1545v thread started by lifter
i rember him usin a el-cheapo power suply instead of the origonal

Thanks a ton!
Hey,
Cruser, thanx a ton! I looked and sure enough he said he trashed his power supply. 🙂 I gave him an email using the forum's send email thinger... not sure how reliable that is... anyone here know his real email? It seems as though he han't posted for a month now, which explains why he hasn't helped me out :-(
I looked at the picture he has, but it hasn't got enough detail to descern what he is using other than, it is really small and definately not the orignal.
Thanx a ton...
I kinda feel like a n00b now though... didn't even think that someone else would have had this problem or wanted to replace the supply... doh
Thanx again ;-)
