del1702fp monitor

Fri Sep 03, 2010 2:30 am   

I have a 1702fp monitor that died. The power light is on but the
screen is blank. I need a manual or some sugestions on a repair
approach.

Thanks
Tony

Sounds familiar. Blown electrolytic capacitors. Find and replace:

When you look for replacement caps (i.e. eBay, Digikey, Mouser, etc),
be sure to get 105C low-ESR caps.

PS... reading the manual is a sign of weakness, inexperience, and
desperation. You probably don't need a manual for this repair.

It's most likely the the tube/inverter. If you shine a flashlight on
it can you make out anything on the display? (I'm assuming a 17" flat
panel?)
Even if you fix this yourself...you would be better off buying a new
FP (or a used one) price wise.

If not the caps, the transistors that drive the inverters are also a known
issue. Kits available on eBay for about $5 delivered [via Hong Kong].
If you don't see a bulge, an ESR meter will test the caps [mine were all
good], leading me to discover the 2 shorted transistors. Now fine.
