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!
