kortek ki-2-vo brand chassis repair help - only high voltage
perjmolsen:
DAMM!!!!!! :applaud:
NOW I GOT PICTURE! :applaud:
Lifted D541 near the HA11235
So, it is x-ray protection... possibly the pot RV537
So now i just need to figure out what type/ohm RV537 is, and then how to adjust x-ray??
Is adjusting x-ray just turn the pot down, and try to see if the monitor turns on? and then adjust it up until it do not turn on, and then a hair back?

I pulled out the RV537 - It is a 5k
Tried to turn it and see what the meter said... it jumped arround...
I have a sh..t load of 472 pot's ;D
I guess that is OK to put a 4.47 pot in..
How to adjust the x.ray? :notworthy:

Put in the new pot, and the diode in again.
Tried to adjust the new pot, but I am unable to get the monitor to turn on... :notworthy:

The pot may just have a broken rotor and not be the problem. This is when a high voltage probe would be necessary to see if the anode voltage is excessive when the protection is disabled. If it's not within the normal range you need to find out what is causing it to go too high. Either B+ too high or faulty flyback capacitor.

I have not tested b+ if I look at the scematic to the flyback it says 115v at pin2 is that what my b+ needs to be?
