Three Major Sega Genesis Problems

Ok. This is kind of a long list of questions, but, I know you guys are the best, so here goes:

I have two Sega Genesis Consoles (Models 1 and 2), I will divide the console issues individually and combine if both are experiencing the issue:

Model 1:

This console will ONLY work with 3rd, yes 3rd, Party A/C adapters. What does this mean?

During the course of figuring that out, I went to clean the contacts that read the cartridge with compressed air, because of the angel, it basically poured what seemed like water all over the contacts, only for a second, but it still completely soaked them. The power was not on but it was still plugged in, I know, not the smartest move, in my defense I am tired. Regardless, it surprisingly only took a half hour to really dry completely, might have been sooner, didn't check that often. Went to boot it up and it actually worked perfectly with 5 games! My only question being should I be worried and/or what can I do to prevent any long term damage?

Model 2/Both:

Both my Model 1 and Model 2 refuse to work via coax or RCA in any of my HDTVs including a Sony, Vizio, and Panasonic. They work fine on my CRTs including ProScan and Sharp.

Any and all help is and will be appreciated! As always, thanks a trillion!

 

Model 1 is designed for negative polarity and higher amps. A model 2 adapter isn't likely to work. (if you somehow made one fit)

Genesis has unusual video that many HDTVs don't like. Even then it often looks terrible with coax or RCA, the console is infamous for that. You'll probably want to save money toward some RGB converter.

 

Understood and thanks for the advice. Any ideas with regards to long term damage from the compressed air spill on the Genesis Model 1's game reader contacts/circuit board around it? Thanks again!

 

-That compressed air 'liquid' is fine, and won't do any damage. Relax.
-The old Coax/RCA connection is terrible. HDTV's often have Digital Recievers built into them, so you have to make sure that you set it to analogue and tune it in (It uses channel 36 as far as i can remember) but i seriously wouldn't bother. Buy/Make an RGB Scart!!!
-Sounds like your official A/C adaptors are faulty. They often broke back in the day as the 'brick' part was heavy and people used to pick them up by the cord, or wrap it round the 'brick' when not in use. If your 3rd party adaptor does the job, then settle for that!

 

the "water" that came out was just the compressed air due to the angle and wont do the console any harm,

i've not had much luck getting the megadrives to work good on newer HDTVs getting a fuzzy picture at best. better to opt for a Scart / RGB cable.

genesis / megadrives are fussy with power supplies i did have my mk1 working with and inverted mk2 power supply although not recommended.
also make sure your official power supply is the actual genesis one and not the gamegear one

should be 10v 1.2amps

and mk2 should be 10v 850mah

 

I don't know about Europe but here in the states those cans are filled with R154a and are not simply compressed air. Its a substance similar to that used in car and refrigerator coolant systems (R134a) but supposedly is safer for the environment. Still just as much a coolant though as demonstrated by the can cooling.

 

i assume they're the same, only thing it might do is possibly leave a residue behind

 

It can and will but it is easily removed with water (hahaha...) or a soft cloth. Again, I don't know about Europe but here in the States we fill it with a "bitterant" which makes the resulting spray taste very bitter if you try to inhale it. This is a poor attempt at stopping inhalant abuse but what it does to me is that I'll wipe my finger against the residue and forget about it then go to eat something.

I hate anti-drug people.

 

That can air stuff burns! My cousins used to turn the can upside down and spray the back of my head with it.

 

Thanks for all the help guys! Just for clarification the compressed air I used that spilled was: 3M Dust Remover (Compressed Gas Duster Contains 1,1-difluoroethane.

Also, it was my fault it spilled, 3M makes a fantastic product! Used it for years and it has worked fantastic!

 

I have a Westinghouse HDTV, it has rather bizarre compatibility issues:
It drops the signal on my Turbografx 16 via RF (nothing that a Turbo CD can't cure, haven't tested any other RF systems except for the Atari 2600 which works)
It drops the signal on PlayStation 2 and 3 systems if hooked up through component video and playing a PS1/2 game (only cure is to change inputs on the tv until you get lucky and it actually syncs the signal, my GameCube works just fine with component).
HDTVs suck for testing systems due to their unpredictable compatibility.
