Jaguar Not Power ON

Recommended Posts

enito > there are plenty of things that can cause a red screen. Bad contacts is the main reason (and that can even happend with a brand new console and cartridge, if the cartridge is not plugged just right). It could also be a damaged track you didn't notice.

 

Basically, the whole cartridge is checked at boot time ; if even a single bit is incorrect, the result is a red screen. So a cut on any address or data line can cause that.

 

If you're patient enough, I would recommend doing a continuity check with a multimeter on every pin of the cartridge port. But I'm not sure if you should bother ; you got sold a "working" Jaguar that doesn't, I would just get my money back and buy another one if I were you.

 

Yep that i think the steps for fix, today i try again multimeter test, i have some photos without cart slot, for see the traces and try to correct (btw, any good quality photo of board without cart slot)???

PayPal claim FTW

 

Yep , i think i take this step, my problem is return console to seller, cause i live far away :(

 

Did he ship it with the game cartridge inserted into the Jaguar?

 

Witouth CART , only console, power supply and tv conector.

 

First time i get this trouble in ebay, everytime i purchase something works, except seller say NO WORK..

 

Greets!

Ah yep, a Paypal claim is the way to go then. If he shipped it with a game cartridge inserted, then I was going to say that perhaps USPS was rough on the package and the game cartridge acted a lever on the board and broke those traces.

 

Out of curiosity, what is the sellers total feedback score up to?

Here are some pictures of a Jaguar without the cartridge port. Unfortunately, a few tracks were damaged on this one too. I hope they'll be useful anyways.

Hi, today i re try to fix this jaguar, i rechecked for 3rd time all pins of cart port continuity with multimeter, all fine, include the fixed ones. I cleaned again the cart slot, and inspect cart pins and apprently all is fine (i used iso alcohol and contact cleaner). But the red screen of death continue :(

 

Hope i can get some more ideas for check...

 

greets

The problem is that it could be a damaged trace almost anywhere. It may even look fine, but be just corroded enough to cause problems.

Honestly, I'm not sure it's worth spending hours trying to fix this - I would return it to the guy you get it from and try to get your money back.

Yep true need to check traces i check but nothing. Yep return but send back is like expensive than the money back . Seller wants jag for send money back. That is the reason for try to fix. Thx for the tips

Me again, checking with multimeter, i found something, but wanna be sure. PIn 12 of U12 (DTACK) going to U13 Pin 41? because i checked continuity and apprently i dont get. Wanna be sure if this read of manual is correct.

 

Thx!

Pin 12 of U12 can't be DTACK, since the input of the buffer (pin 8 ) is DTACK too, and that wouldn't make sense. It's hard to read but it looks like it's DTACKL, which is connected to pin 15 of U15 (Jerry).
