Chungwa CRT monitor not displaying red

Yes that is correct, I just replaced the pot and the red had no improvement.

Have you tried removing and reinstalling the socked chips on the main board.
You should also look for cracked solder joints at the plug connections
primarily the connector for the monitor.

I am so dumb, thank you I have fixed the issue. The solder joint for the Red connection on the monitor plug was a cold solder join (not good connection). Thank you so much. Just reflowed the solder and added some new and it works like a charm. Thank you again. [palmface] not sure if gif exists...

As my dad all ways told me-
"KISS - Keep It Simple Stupid"

All ways check the simple stuff first.
I - we have all been there - Done that many times.

 

Glad it was something simple and you have it fixed.

PS: you re-flowed all the pins for that connector?

It actually stopped working again it was a broken trace. I just added a jumper wire.
