wow i thought someone would have commented by now ,something, anything, i guess everyones as puzzled as i am  , Are there any known monitors that use a 13 pin neck pcb? only thing ive found out is most likely high res because of the LM 1203N , again any help in identifying this chassis is appreciated.

lm1203 are used many different res chassis
i have never seen that chassis before

The chassis has a Taiwan look to it. Could be a Jen Shinn.

It's got a switching power supply in it so no isolation transformer would be needed.

The LM1203N chip on the neckboard is used by many monitor and television set manufacturers. Definitely LM1203 is used with different resolutions.

  you are both correct,, some more googling and youll never believe ive found out what it goes too .found an image of the back inside of a Taito Classics Bartop..and to my surprise there was the mysterious chassis! i would have never believed it had i not seen it with my own eyes.now if i could just find schematics on it and a tube ill be good to go! thanks for the input grantspain and ken.

turns out to be an Irico 37SX110Y22-DC05
 

[Ken Layton]

What resolution is it?

[doubleD]

ken all i can find is that the game was jamma wired, and cga . info came from http://web.archive.org/web/20061102175106/www.retroblast.com/reviews/GameRoomClassicsCabinet-08012006-02.html so i assume its standard res but cant find anything on the monitor its self.

[Ken Layton]

Irico made the picture tube. The tube # is 37SX110Y22-DC05. The 37 means 37cm diagonal measurement across face of tube.

This still does not identify the chassis though.

Appears to be all China made stuff...... including the bartop game in which they might be found.

So the chassis is probably made by someone like :
Irico - Royal Electronic Information Co.
or
Shenzhen Irico-Royal Information Electronics Co.Ltd

The tube is listed as a 15.75khz though.... CGA ..... so at least that much is known.
Seems to be used in several 14" televisions overseas.

true kevin thats the same info ive come across . difficult monitor and chassis to find info on. sorry ken ,didnt mean to post incorrect info.got ahead of myself .

[qrz]

is there a problem with the chassis , or just trying to ID it ?

if it is chinese made , info WILL be difficult to find, IF at all  . just as it is with most chinese electronics

Based on the picture, very simple board a few comments:
- Ken is right switch mode supply no iso required. Feed back is through an optic isolator to regulate the voltage so likely PWM supply
- It is almost certainly CGA/Standard res only.
- The Ha 11235 is for processing the sync etc.


As I mentioned seems like a simple board, and asked earlier in the thread, is there a problem or just tring to find out who made it??
