No worries, I'll keep it for parts or a possible educational project with my son.  Assuming it is the VRAM, do some of you know what brand/spec to get and where we can buy them?

Thank for the suggestions.  The cost and trouble of acquiring the specialty bit, tip and VRAM chip without knowing if it will resolve the problem is a lot less appealing to me than forking out $35 for a used working console.

Unfortunately, after several attempts to clean the contacts by pouring rubbing alcohol on a HuCard and repeatedly re-inserting, it did not resolve the problem with the graphics.  I'm not that familiar with the architecture of the TG16 but my understanding is that there are two 8bit graphics chips?  Since it is always the backround that is missing, could it be that one of the chips or board is defective so that only the output of one of the chips is working?  It would make sense that game design would have one chip dedicated to rendering the objects and the other the background.

At this point I'm wondering if it may be cheaper to buy a used working console.  Any ideas?

Aha! The TG16 unit was dusty when removed from storage and while I wiped the outside it is likely that the contacts inside are still dirty.  The hucards were in their sleeves so they should be fine.  I will try the rubbing alcohol trick with Keith Courage so that I won't care if it damages the card. This sounds much simpler than "replacing  the crystal".

Greetings, I'm a new poster.  I last used my TG-16/Booster some 15 years ago and decided to get it out of storage as my son is now old enough to play some games with dad.  I hooked it up to my Aquos LCD and while the hucards worked, some graphics are not being displayed (background is missing in games like AirZonk, Dragon's Curse, in Bomberman93 we see the Bombermans but not the walls or bombs.  I tried both the RF connection and the RCA connection from the TurboBooster but I get the same result.  Thinking that modern LCDs may not support the video signal out of the TG16, I then hooked it up to a 10 year old 27" tube TV from but I was dissapointed to see the same result.  I now think there may be an issue the TG16 itself and I was hoping some of you may know the problem and possibly how to resolve it.
