Hello OCAUers, One of my old school tubes has suffered a full vertical collapse since the last time i ran it (back in 2014 ). I was able to find the electrical diagram for this unit, but since i've never repaired CRTs, and realize the caps and flyback hold high voltage, im weary on starting any repairs on the mainboard (like swapping out the vhold IC) This model does have a vhold pot on the front, the wheel seems undamaged and i doubt its just a bad pot. With all this pandemic business going on I'm unsure if i could get anyone local to repair it easily. Not sure even where to start to seek pro repair or whether i should learn the safe discharge practices and give it a crack myself. pics of it back when it worked: pic of it in its current sorry state: I can tell its only a fault with the screen itself, since the unit appears to function. There's a fray in the main data cable to the unit that causes some of the alignment to go out intermittently (h-hold) when the cable is moved slightly, but this collapse appears unrelated and more to do directly with the vhold circuit or caps, since the fray does not alter the collapse at all. Anyway, i'm expecting the usual safety warnings like dont open it up and try discharging it etc. which is fair enough, and Alternatively I could use the unit with a video out adapter, it would cost me about $45 to get it running to HDMI and ditch the CRT, but that doesnt seem the purist approach even tho its probably more cost effective than a repair, and a complete working replacement CRT would set me back about $180 from europe. bring on the advice boyssss!
