[Console Repair/Mod Center / Re: TG16 Blank Screen]

I've only got 3 cards and a Turbo Everdrive. None of them work.

[Console Repair/Mod Center / Re: TG16 Blank Screen]

good bet on traces
the results are the same for all cards its likely an issue with the CPU connections(or chip)
color encoder and grafix chip failures generally wont generally change color or give dots

So should I just go nuts with my multimeter to try to find broken continuity? I'm not sure where to start.

Good to hear that it's likely not a bad chip. The last few times I tinkered with it I was only getting a white screen, if that's an indication of anything.

That's too bad.  I'm outta ideas.  How about testing your power supply with a multimeter to see if you're getting the proper voltage and amperage from it.

I did check the voltage coming out of the power supply last night. I believe it's supposed to do 10.5v, right? When testing just the power supply (not plugged into the console) it was showing about 14v.

This didn't surprise me too much, since I know that some power supplies will show a higher voltage until they are under load. Maybe that's not the case with the TG16 power supply?

The other day I checked the 7805 voltage regulator and it appeared to be outputting about 5v.

I didn't check the amperage. I'll try that tonight.

I tried the coffee filter trick. The console slot appears to be clean — no gunk came off at all after repeated tries. I even tried three filters at once.

I'm still just getting that blank (almost always white) screen with no sound.

I tried looking at the slot head-on with a bright light. As far as I can tell the contacts all looked fine.

Try cleaning the Hucard slot.  Take a coffee filter and cut it with scissors to match the width of a Hucard.  Douse the coffee filter with rubbing alcohol and wrap it around a Hucard.  Remove and reinsert the card repeatedly.  See if any dirt or goop is coming out.  Repeat until clean. Retest. 

Thanks! I will give this a shot tonight.

It's possibly still a cap problem (bad cap, bad connection, etc.) or a trace damaged by leaking cap juice that needs repair.

FWIW, while recapping I checked each cap as I removed them with a capacitance meter. They all appeared to be correct.

I did not replace the cap near the power plug or the cap in the RF unit.

Question... are you using the RF out or do you have a means to use A/V?

I am using composite, yes. I got the same results when trying RF.

Hi — I'm hoping someone can help me with a problem I'm having with my TG16.

A few months ago it suddenly stopped working. When I try to turn it on, it gives me a blank screen. Usually white, but sometimes pinkish or yellow. Occasionally it will show some odd dotted patterns.

I've tried it with numerous games with the same result. I've tried fiddling with the hucards to see if maybe there's a bad connection and nothing seems to help

So earlier today I recapped it, but I'm still seeing the exact same problem.

Is there anything else I can try? Does anyone have any idea what might be causing this?

Thanks!
