Just got this monitor and was dead. Verified that 120 Vac was going into it, and it was.
Visually inspected it, and tested a few components. So far found that Q801 was bad and burnt, R812 was burnt but still tested good, C807 tested good, and D805 tested good.
I had one other pretty bad burnt mark on a leg of R801. How do I test this and what is it called if I need a replacement? I looked at the schematics and looked like R801 was two resistors, but didn't see the values of these. There are three leads coming off of R801, so I would imagine you can find the resistance between the two of the three legs and repeat. Is this right? Any other common failures not mentioned on Ken's guide?
I attached a picture of R801. (This isn't a picture of the chassis I am working on).
Thanks!
Theron
