Hi guys! Not been around the retro community for a bit due to limited time but managed to dig out my Jaguar today for a blast.
Unfortunately it appears to be knackered and before I start poking around in it I thought I'd post here first.
The power LED illuminates as soon as I apply the PSU input. Pressing the power button has no effect, the LED stays on regardless (power button does seem to be 'clicking' between on/off states). This happens with and without a cartridge in.
Its not acting as though its powered normally either, as I cant tune it into the TV.
What do you think about that? On face value it doesn't appear to be any of the common faults.
Anyone know of any good resources I can check out, or have seen this issue before?
All the best!
Good to see you back! Sorry that you're having issues with your Jaguar. I can't really help you as I have no idea how to fix any of these consoles. I hope someone else here can give you some feedback.
Never heard of that problem before, it's a strange one. Sorry, no idea what could be causing it.
Yeah it's strange one. Hopefully I can get it sorted as this particular machine has some sentimental value attached.
As an aside, I've installed Tapatalk in an attempt to keep in touch with the forum [emoji106]

Good luck fixing the console. Cool on Tapatalk. :)
I've never heard of that issue before either. Wish I could help but no idea what could be causing it.
I think you need to open it up but I suspect the latching of the switch is jammed on I would say, could also have HR and if I am correct it controls the 5V + & -
You da man zapiy. Save the pus... kitty!
Lol
I ain't saying that's the fix but to have power past the switch I would certainly say that's faulty.
I hear that. May not be a fix but definitely a step in the right direction. The rest of us didn't have a single suggestion so any help is better than none.
I hate when a Jaguar is broken and even more when there's no solution or ideas on how to fix it. Grateful for the info in case the same ever happens on my end. Great stuff!
Cheers Zap. Is a jammed switch something you've seen before?
I'll try this later in the week as I'm just heading out of the country (currently having a brew in the terminal). Jag is already in pieces in kitchen. Wife is very happy about that... [emoji85]

Switches are a common failure point in our line of work, not suggesting the Jag does but a brief search on google I found a couple of sites suggesting the console does suffer with switch failure.
Hmm......
LED on with switch completely removed

Hmm, that may be the culprit.
Yeah you could be shorting across those tracks.. How you looked at the schematics?
Yeah I've got the schematic.
I'm going to try changing the voltage regulator IC, that seems to be a common thing.
As far as I can tell it should output Vcc of 40V but I'm only measuring around 9.3v which is consistent with input voltage. This would be enough to illuminate LED I reckon. Can't tell if its dim or not as I've no comparison lol.

Still waiting for components to arrive...

Has it been longer than expected?
Nah, not really. I ordered some regulator chips from a Chinese seller so could be another few weeks yet.
I actually ordered 5 as it was more cost effective, so if anybody needs one I have a few spare.

Oh, yes, if coming from China it can take a few weeks.
I hope it's worth the wait and it all works in the end lol.
I need some Tempest 2000 action!

Look forward to your results pal.

Good luck, that is a frustrating fault to analise and fix.
No luck :^[
Stuck the new regulator chip in and the console now turns on and of like you would expect but unfortunately there is no video output, or nothing to tune into at least.
The investigation continues....
Aw man, I was hoping for the best. Good luck with the further investigation.
That sucks. I hope you're able to figure out the issue to fix it.
Well done for getting this far pal.. I am sure you have the determination to figure it out.
