apparently this one has the same problem. bad run i guess.


I REALLY need that part number of the chip, bolted to the heatsink of the
CRT neck board. mine is white and toasted crispy.

I got this 22" monitor, its got the same problem with the opto-isolator i
seen going around.

this monitor has more severe damage done to it though. I see several
electrolytics that have popped open. around the power supply, vertical
IC, and one on the neck board, couple in the HV section.

the HOT and damper test ok. the power will not come on, it just cycles.

there is a large 15-pin IC on the CRT neck board that is exploaded and
unreadable. Does anyone know what the part number of this IC is? I can
definately tell you its not LM2412, this one is 15 pin, different package
style.

its white and split open from smoke and fire.

im assuming all the caps, this IC, and the vertical parts will need
replacing, along with the opto.

any ideas?


Unfortunately I no longer have one of these to look at for the numbers but
what's the deal? I've fixed at least half a dozen Viewsonics with the bad
opto and probably more than that. I've never had one come back after I
fixed it, did they just get a bad batch of optos?
