Got myself a small crt tv for making an arcade machine, thing is that I couldn't find its service manual anywhere, and there's no model written on the TV as well.
The only thing I have is the TV chassi and the microcontroller model, but EVEN so I could not find their respective service manual and datasheet.

The chassi is:
f-74/316f
It's a Toshiba max color, 14''.

The microcontroller:
374641/ST-002



If you manage to find the microcontroller datasheet,
please tell me if it has an analog RGB In.

 

Looks like the chip is available from Brazil..

Any more information on the TV?

 

Post photographs of the TV, front and back.

 

Maybe... SAMS Photofact Online | Austin Public Library (austintexas.gov)

 

Hello,

There are several manuals for toshiba models starting with 14 here:

Hey fellas, I managed to find a few things. The model label was on the board, and although I could barely read a thing (too erased), I could see that it looks like it uses the service manual TV 1480E UV5 or TV 1480E-2080E-2080M (probably this one):




One thing for sure is that it has a TA8718N IC, so I found its datasheet. I saw that it shas some RGB Clamp, but I couldn't identify its Blanking line and AV sync. By the way, this tv doesn't not have a physical AV In behind, but the TA8718N seems to have a sync in.

Everything is attached in this message.

Can anyone tell me if this IC has a analog RGB in with both sync and blanking line?

 

No that chip has Luminance in and separate RGB out..

 

TA8718N is receiving the microcontroller RGB signal where it's written R clamp G clamp B clamp, so RGB clamp is an input, not an output. Also, someone already told me that the service manual is using an equivalent IC for the microcontroller.
What I mean is that the video is coming out of the microcontroller and getting in the IC Jungle, but I can't identify the C-sync and the blanking line. And it's probably an analog RGB, because the TV is too old.

How about these Y-OSD and TV/VIDEO on the microcontroller? Can one of them by the C-sync.
