Kortek MP-KT2182 chassis - no image, ticking
« on: February 06, 2020, 11:17:01 am »
I've seen some great troubleshooting on an old thread that I tried to follow for my situation, but it seems mine might be a little different.

My monitor went out the other day.  Pulled the main board (Kortek MP-KT2182), plugged it in on the workbench and I get ticking.  I found the Horiz Output Transistor and it's a 5 pin.  VCC (+50V) and drain voltages are not steady.  Outputs from the main transformer are also not steady.  I don't have the tube or neck board connected, if that makes a difference.

Where should I go next in troubleshooting?

TIA!!

Any ideas or places to start?  I'd like to get this buttoned back up!

Thanks!
