LA7673 Datasheet and LA7673 manual
Hey guys, I have a sanyo 14″ tv that I took apart that I was thinking about using for a small arcade machine. Unfortunately it only has coaxial inputs. That would work for the color signals, but you still need to put sync in somewhere. The composite video input works for that.
So, while it will work, it may not look the best. You lose all the color adjustment and processing that the “jungle” chip provides.

In addition, you’ll need a video amplifier for it to even display a usable pix. You need to be up around vac to be in the ball park. With a little hackery, this is often possible. What you do is generate CVBS using a little combiner circuit, apply that to the composite input to get the thing to generate all the deflection, then yank the existing RGB lines and apply RGB video to them directly. As boardjunkie said, a video amp will likely be required. I can’t find any docs on the LA IC you have pictured nor can I read any of the othersit’s difficult to know much about how this set works.
It might not be the best candidate for this kind of modification. Oh wait, this thing doesn’t even have a composite video input. I wouldn’t bother with this thing at all.

May 07, Oh well I guess, I found the tv in the garage I too tried to find at least a pinout for that chip, came up empty handed as well. Heh, I guess I could try that. I got a response from sanyo support, it was a rather “dont bother us” canned response, but a response nonetheless.
I found a link in one of the many PDFs stating that this IC was discontinued in march ofpa7673 I tried emailing the semiconductor division to see if I have better luck.

The TV may have been made inbut the part was only discontinued last year, there has to be some details laying around somewhere I got a response I dont know if datasyeet a perfect match, but it does have the same amount of pins I will have to do some testing and see if some of the pins match, you might just be a savior! I would say it’s not very likely. I’m thinking that chip was made for that particular television or series if l7a673 going to toss the TV it couldn’t hurt to experiment with it.
Yeah, I dont plan on using the TV, so might as well futz with it till it blows up To be honest, I fatasheet my way satasheet electronics, and I can read a schematic, but I wouldn’t really know where to begin here with this one May 27, The best picture I could get of the solder side of the neck board is already at the top of this post, just right click the datashet and “open in new tab” to get the full image, i’ll work on the component side, but the lighting blows in here I traced pin 18 R-Y out from the IC, it goes to pin one on the cable that goes to the neckboard, which happens to be labelled R I think this may be a close enough match to get me the correct pins at least.
Can I just feed RGB in at these pins? Where would I put sync? Man, I wish I knew more about this kinda stuff
