BEOCORD 3500 (4500) DEAD…ish

[Dillen]

Weak power supply?
Check power supply voltages.

What about the bigger cap for the Dolby chip right in the middle?  Not dead as usuall?

not had a chance to test the supply voltage as yet. any tips as to best practice? I’m fairly competent, but wouldn’t want to make a mistake.

i tested all the big caps first and they all check out ok. it just feels like its underpowered, so agree its caps (probably ruled out) or PSU (still to test) or …something else.

Just wondering why on the odd occasion, it powers up fine with buttons working, all be it sluggish.
