Re: Replaced 820F caps on syncmaster 2253BW, backlight still shuts off after 1s

Did you notice a pink hue before it started to shut off, or can you see it the very short time the lamps turn on?
If that's the case, it is a bad lamp.

Re: KDS K-92BW Turns off

Post Re: Samsung 226BW

No sound or pink hue?
If you connect it to a video signal, you should be able to see the screen (dimmed) when the lamps go out by using a flashlight. If you can't, besides the inverter/backlights we...

Re: Samsung 226BW

Just to be sure...
Screen DOES lite up and then goes off....?
My main question would be, do you note any noise between the On and then OFF , like a hiss, or a red/pink hue in the screen?

Re: Viewsonic VP211b

just got my hands in one of those units, and the problem ended up being the logic board (besides the recap). I have some parts for those units, so I just swapped it and that was it. I will find time...

Re: Issue with Westinghouse 19" LCD Monitor (large pics)

And as for knowing nothing, I was a bank teller when I joined the forums (unemployed now...) and did not know nothing,except to...

Smile Re: Issue with Westinghouse 19" LCD Monitor (large pics)

1.- Caps are not the recommended replacements.
2.- Without changing the MOSFETS you will never get an image,even if the fuse is bridged (the fuse blew because the MOSFETs shorted...)

Post Re: Issue with Westinghouse 19" LCD Monitor (large pics)

Re: Acer AL1916W LCD Monitor Power Problem

I agree. Most likely a 700G(900G in this case) style PSU/Inverter board on the inside. Most of the time there are cap problems only.Follow Alexanna's suggestion (and PlainBill's instructions) and...
