Tiviar Alpha Plus - Dead after powered off for a week

Dutch Roll

Ok great thanks. I gather the brown sludge at the base of the capacitors is actually glue or something and not the capacitors leaking all over resistors and other nearby components?

Would you recommend I replace all the caps and not just the big one?

NewClareman

Yeah, just glue.

Ideally you would replace all of them.

In fairness replacing the PSU with a laptop power supply was very easy, just a pliers and a few connectors required. Took about 20min and €25

Dutch Roll

Lovely. I think that's what'll I'll do. Pretty straightforward I'd imagine. Thanks.

Dutch Roll

Any ideas lads? I think I've bricked it.

I fit the laptop power supply, got this on the display. Then put back in the original PSU and still getting this on the display.

Reckon it's a gonner 😢

I suspect that some chip is blown. Hard to know what has gone wrong. Is there any chance you put in the laptop PSU the wrong way around?

Dutch Roll

99% sure it was the correct polarity, I was very careful. Nothing popped, no visual evidence of something going wrong. But I must have fried something.

I'm no worse off than I was last week but it's a shame as the box is just over 3 years old.

Reviving an old thread here

My brother's Tivia Alpha has died ( won't power on) Mine shuts down randomly..I get it going by switching off and on via the rocker.

Is it an easy fix to put a laptop power supply into these?

There was a little link to thread about the faulty PSU problem and what you need to do to switch to laptop power supply.

Can anyone help with info ?

intro

Hi KS,

Its an easy fix. a clanger had a thread on it but it appears to have been deleted in the "update" a few years ago.

He sent me pictures and more detail about it. I'd prefer not to post his pictures without his consent. He's still active so he will probably be along in a while.

It was easy to do and worked for a while but the box eventually gave up completely a few months later.You need a laptop power supply , this is the one he and I used:

You will need a kettle plug lead with that one as its not included and a few strip connectors or wago connectors.

One of the male plugs of these if you don't want to cut the connector off the power supply:
