NO RED, & NO SIGNAL on my Wells D9200

[jconstanza]

My monitor started off with a Vertical collapse. Replaced a cap on it, turned out good except no red. I have swapped, Q201, IC201, IC202 and nothing. Then I swapped IC403 and IC101. Checked cold solders...nothing. I had the Wells pattern generator hooked up to it. After I swapped transistors it started giving me a "No Signal".  I'm friggen stumped!

Yes, I actually do use the website a lot, but that only gets me so far. This one is tricky, well at least for me. Wells says to try IC201 (did that), R228 (resistor not on board), Q202 (did that). So where do I go now? I think I even tried a different neck board. I was able to fix the "No Signal" problem. So now I'm just missing red.

Have you tried swapping signal wires around?

Does your red lead make the blue or green come on?
And vice versa.... does your blue or green lead make the red come on?

You may want to check your color settings in your osd menu as well.  You can get into the factory menu by holding a couple buttons down on power up.  I cant remember which ones though.

thats a good point,i remember a problem with pentranic digital monitors whereby once in a while they would get a static zap in eeprom and do weird things with brightness and colours and thus only required a factory reset
