|
|
i would check the neck boards on the crts one might have worked loose(i had that happen with my ecp after i got it home) if the crt isn't bad
before calling a shop open the back and check for loose connections as they can cause the unit to not work right is the power light flashing a error code
i am working on a samsung projection tv(needed a new red tube) since then i have had to replace the neck boards and it needs a new convergence amp board(don't ask)
this set can be fixed its just finding out whats the source of the problem

it depends on if something needs replacing
if you can upload a few pics (one of the back where the inputs are the rest after you have the back off)
i am pretty good with working on a tv so i should be able to help you once i see some pics of the inside of the set
also the convergence amp boards(and the stk chips) are a common issue with crt projection tvs and that may be the cause of the convergence being off(and possiblely not doing a thing(mine is like that because of this board))
if it turns out to be the convergenc amp board(and nothing else is loose or bad) it ain't that hard to replace
fyi the cost of the repairs i have done on the samsung i have so far is less then a 23inch lcd tv(so it is cheaper to repair then replace the tv when it retailed for 3 grand when new)
i wll warn you before you go pokeing around in the set UNPLUG IT and let it sit for at least a day(respect the high voltage section)and keep one hand in your pocket(safety precaution as i have worked on enough of these type of tvs to know what i am doing
so far on the samsung i have i have replaced to red tube(old one failed) the neck boards and will need to replace the convergence amp board(had the red tubes yoke disconnected and powered the set up(bad idea)oh well live and learn

Ok, from what i can gather you say you connected something to the composite or s-video? Is that what youre saying? Cause if so, that may not work, this thing will likely not have an input board ( maybe ) and may only accept RGB. That is common with the Mitsubishi 50" TVs SEGA used at one stage, and i think the Toshibas they used were like that too, i cant remember. NAMCO may have done things differently, i know they used a Pioneer rear pro in the 50" Point Blank cabs at one stage here in Australia. Konami even used 50" Sony sets in early 90s.
2nd pic, turn the set off and clean the deflection yoke connectors. Image should be stable.
Need to see inputs, but moreso with the back cover removed.
It will be something simple cause youre getting menus. The colour balance will be shot from tube wear, its probably fine to adjust G2 with the pots at the front of the set on this TV. That might be why there is no blue, but probably not, could be a few things.
Youre gonna be alot more likely to get this thing working from this forum than from Aussie Arcade forum, and itll be understood better here that you want CRT ( fact is you need it for Time Crisis to work )

On the front of the tv, press the AVX and power button at the same time and see if any codes come up onscreen.

If it's a US-built Time Crisis, it's just a standard off-the-shelf consumer set. I have a couple of Namco 50" games right now (and have owned others) and they've always had Mits sets, so yours might have been replaced at some point?
They're usually Mits VS-5042 or 5043.
Japanese-built Namco games have projection chassis (Pioneer, I think) put into custom cabinets, like Sega always did with everything (they used Mits, Hitachi and Toshiba all built into the same standard-size projection cabinets), they tend to look nicer IMO, since the screen is better integrated with the cabinet, but at least the US-Namco stuff is easier to repair since it isn't rare hardware.
Namco has a RGB to S-vid converter in there, so it's just 15.7khz, obviously. The Sega stuff all runs at 24kHz (RGBS BNC), and 31.5 (HD15) with the later games.
Any way you cut it, the tubes will be shot. The TV just sits on a shelf in there. I'd suggest to just find another 50" 4:3 set for free from Craigslist, or whatever your local equivalent is, and swap the entire thing out. Otherwise, you could find any similar set to pull tubes from. I've actually been doing this a lot lately with 50" Sega machines I have with Toshiba monitors.
Not trying to threadjack, but anybody have any idea which Mits sets (or at least size & era), used long-neck tubes with 1 HV lead to the flyback? (no splitter, anodes are daisy-chained). Most of the consumer sets I run across have short tubes, even mid 90's 65" stuff. Maybe 98-2001 60"+ stuff? Need something that will work for the 7 or 8 50" Sega/Mits sets I have 
Since arcade machines run for most of the day, every day, projection games usually look like total crap. They don't look much better when people spend $1k to convert a 50" 4:3 to a 42" 16:9 either.. not to mention a retubed projector will probably last longer!
here's my project lately:
and what it looked like until a couple weeks ago, with one set of tubes replaced for comparison:

I don't know. The green still looks pretty strong in those posted images of RSOP. I would pull the lenses and check tube condition before condemning. Hitachi tubes aren't known to burn up tubes quickly.

Yes it was me that sent you here mate, cause the people here will give you a much better chance at repairing this set 
Are they DVB180 tubes in those sets?

Ok here are some pictures, Im no wizard so walk me through it :p
Also I'm not to sure what these cream blobs are over the resisters? leaking?
Hope these images help.
Also this is just something in the air I was thinking about. What if I was to put a small projector in there and reflect it using the mirror inside the TV would that actually work?

The white blobs is silicone to prevent the connections from coming loose
Forget about a small projector unless its a crt(the others won't work I have tried)
Also here is something that may help you
http://ohwow-arcade.com/Assets/Game_Manuals/TIME%20CRISIS%2050%20inch.PDF
I did some searching on line
From what I see the set looks pretty much intact just have to figure out what is the issue(not sure on the fan)
You can find parts for this set online just plug in the make and model number as it looks like a off the shelf consumer set( I also looked that up)

The fan is extra, not connected to anything now but just something I assume the arcade tech might of put in to keep it cool since the Fan has a australian retailer on it.
Yea I believe its a off the shelf tv but there is no way of taking it out without breaking apart the cabinet because its actually built into it. No wiggle room at all hahaha.
As for the projector, technically though if i was to remove guts of the tv and leave the mirror what kind of projection would I get? I know light guns are only made for CRT but I have something else planned for this. Just would like to know what kind of image did you end of getting or was it because of the draw distance you didnt get much of an image at all?
E:OH wow, thanks for that, was searching a while for this

If you do want to install a projector in the cabinet it would have to be a crt projector like curt sales
I tried a dlp projector in a tv one time(picture was ok but not bright or as good as it would be with crts as it was smaller the screen size of the tv)
Now if you are careful you could fix the set as it is(word of advice don't break the crts as they are getting hard to get now adays for consumer sets)I am fixing a samsung set my self(I will agree they have made them harder to work on from what they used to be I had one set that the whole light box and everything came out at one time

Thanks for the advice
As for the projector, I was actually planning on getting the (BenQ GP2 ) as something for the small room we have, nothing flash. Then it hit me I could put it inside the cabinet and it might work, If it did I would be laughing.
Also for the Hitachi Tv, I would need to find the original remote right to do all the programming or would a good universal remote work as well?

A factory remote would be best but any programmable remote will work with the tv
As for the projector I am running a elctrohome Ecp 4101 with a 10 foot screen(bliss I tell you)
The samsung tv I have is for the possible change my projector goes down (its being fixed for my backup unit)
Also the projector I mentioned is HDTV capable (even better) plus it is a great price just email curt
Projectors are ment for a large screen not a small screen(consumer sets are not bad hence why I am fixing my samsung) but you would shortchange the projectors abilities in the tv body
I went from a dlp(optoma h27 with 4000.1 contrast) to the elctrohome with 15000.1 contrast with a 10 foot 16:9 screen and loving every minute I use it

If you put a CRT projector in there yous need to swap the tubes to the original LC housings cause there wont be enough throw distance there for standard lenses.
The LCD or DLP route will work fine, but no gun games ever, and you need to be sure the projector you choose has zoom lens and is compatible with the signal.
