I spent yesterday afternoon swapping out the 50" mitsubishi in my Crisis zone with a 50" Hitachi. About 2 months ago the convergence went out. After changing convergence ICs and countless resistors and capacitors and not fixing the problem I started searching Craigslist for 50" tvs. Finally after several weeks of getting no responses from about 8 "sellers" I got a call yesterday. Picked up the Hitachi for $100. I took the mirror out and cleaned 8 years of film off of it as well as the projectors. It was about an 1" taller and wider then the Mitsubishi, so I had to remove a lot of the blocking inside and wrestle it in. Turned out great, the tv has a great picture and no screen burn. Has anyone else had luck finding 4:3 50" tvs and swapping out in Deluxes?

I haven't done it but I know the day is coming and I'm on borrowed time with my Rally Deluxe. I know projection screens aren't as bright as an LCD or tube, but did you notice your picture being a bit brighter putting a new/old projection screen in there? That's my main complaint, is picture brightness compared to my other games. I did take off the front screens and clean the mirrors and screens, as well as adjusted it up as bright as it would go without blooming.

Yes, the picture is much sharper and brighter, it looks like new, I think I got lucky finding a tv with a really good picture.
 
It's good to see this can be done, but I'm hoping to get my Star Wars Trilogy projection tv fixed. It's got a vertical deflection failure that I haven't been able to track down yet. It sucks there is little to no documentation for these things. :(

Very nice looking, and I forgot to mention Crisis Zone preferrably with the large screen is on my want list. I'm glad the TV swap can be done without too much problem or cost.
 
This game does use an infared camera in the pedestal Actually there is a thread somewhere on here a few years ago I retrofitted a 42" lcd tv in this game. The LCD screen interfered with the IR, if I turned the tv off and plugged a small monitor in I could see the gun tracking, but as soon as the tv was turned on the gun would no longer track. That is one reason I needed to find a old projection tv. I believe old projection tvs can flash the crt, I remember playing some shooting games on my old projection tv on ps2 years ago.
 
May be a dumb question, but, does it use IR tracking for the gun? Light guns always say they won't work with projection TVs.

I think Crisis Zone has an IR output LED in the gun and a black and white CCD Camera in the gun base. That game can use any kind of monitor you can throw at it. 46" LCD's work too.

Question to the OP, whats with the red lights in the marquees?

Yeah, I've done a few swaps... not all games can be swapped with TVs though. Most Sega games use 50" medium resolution monitors, so you really have to swap them with another of the same type, or get an adapter board. My Top Skater is using a monitor from a Sega Super G, and I just peeled the art from my original and reglued it to the new one.

About the rear projection monitors being dim, I've noticed that on a lot of them as well... luckily I've found that a rejuvenator works great on them, and gets them looking great again. I've rejuvenated 3 or 4 of them, and they've all gone well.

Yea a tv would definately be easier, I have never seen a 50" medium resolution monitor, who manufactured them and were they a 5 wire RGB ground and synch connection? Crisis zone uses just a regular 50" tv, the cabinet has a converter board that runs s-video to the tv.
 
Many Sega model 2 games used 50" medium res monitors. They had only 4 wires running up to them for signal but the cables were sheilded so theres the 5th wire (the ground). R/G/B/GND/SYNC.

Toshiba and Mitsubishi made the monitors.

They have a plug for 100vac and then a red blue green and white wire on somke weired rotate-to-lock roud connectors.

Ive seen three different makers.. toshiba, mitsubishi, and umm.. hell i forget samsung mabye

They are simular form the outside but inside they are TOTALLY DIFFERENT FROM ONE ANOTHER


When my trilogy monitor puked i made a treck to troys(mtzrcade) and picked up a top skater monitor, gutted it, and put the guts in the trilogy monitors box( to save the art)


It was a mofo. I wish i could have used a regular big screen tv but i have a bad feeling they wont sync, if you could even get them connected.

Happ sells a retrofit kit to put a lcd into the original box, its like $1000+

Unfortunately mine is a Sega model 2. Just curious, how do you rejuvenate a rear projection, with its 3 color projector lights?
