Title: Name That Monitor's Problem!
Post by: RetroJames on March 08, 2005, 10:52:34 pm: I am auctioning a few 19" monitors, all have some issues. Take a look...

But more importantly, see if you can diagnose that problem. I am curious as I was planning to troublshoot and fix them, but as you know with this hobby, sometimes you need the $$ right away.

Mostly I am curious about these two:

(#2) - Half Screen - (Sorry no pic, but read description) - http://tinyurl.com/6txy7

Post by: Ken Layton on March 09, 2005, 02:22:59 am: Sometimes resistor R313 (470 ohms, 7 watts) which is mounted vertically in the corner of the board goes open circuit which also kills vertical deflection. Capacitors C313 (100 uf @ 160 volts) and C701 (1000 uf @ 25 volts) cause vertical height problems when they go bad.

You could buy one of the Wei-ya replacement chassis that retrofits the Electrohomes from either one of these guys:

One of those chassis would repair your old CAO and it comes with full instructions. Plus the replacement chassis uses negative sync!

Just ordered one from Alva yesterday, thanks. It only cost ~$58 with shipping for the G07 replacement. Seriously, if you want the CAO chassis let me know (free for you). Otherwise it'll go up on ebay.

Post by: Ken Layton on March 09, 2005, 11:21:50 am: No, I don't need it. Thanks for the offer though. :) Go ahead and ebay it and hopefully it'll bring you some money to offset what you've spent on the CAO. Let us all know how your new Wei-ya chassis works & how you like it.
