METRIX OSCILLOSCOPE DEAD

[Ketturi]

I gave one last chance for this scope. Front panel was not working because one smd 74HCT08 was fried on the front panel PCB. It had visible burnt hole at middle of it. I also changed all electrolytic capacitor from the power supply section and also UC3842 IC.
I also had to repair some bodges that were broken, this scope is so full of them, every section has some smd components soldered together and there was some drilled holes on traces and diodes&transistor soldered over them. Power is still bit intermittent, and it does not want to power on every time.
I found small metal contact inside the scope from time base encoder that also was not working, glued the contact back. It is possible that it had broken of and then shorted something else inside scope. I do not know if I want continue troubleshooting this scope because it is terrible mess. I have never seen such badly designed and bodged scope, and repairing it is pain because everything must be removed to get access to main board. CRT can't be disconnected easily as it has soldered ground connections everywhere (even inside metal shielding)
