Title: Pc Engine LT AV Input
Post by: wolfman on 04/03/2014, 05:24 AM
I am calling all owners of the LT in on that topic - I have a question:

Since mine is a modded version (composite from expansion port to LCD input), I have no expertise on the A/V input jack on the side. I don´t get a picture, either from the A/V input nor from the TV section (at least a noise picture should show up if I flip the switch...wouldn´t it?).

Is the jack directly routed to the composite output on the expansion section or via RGB thru the video chip? I have tried to send a video input signal from my DVD player to test this (PAL, since my LCD supports both PAL + NTSC), but I don´t get a picture.

Maybe someone else has tried or tested this before? I don´t want to open up my unit just for playing around with this...some hard facts/experience/tests from someone else who has tried in the past would nice.

You should get picture noise when selecting TV input, so there is something fishy.

I succesfully hooked up a Famicom to my LT with a simple Stereo RCA to 3.5mm adapter cable. Be it antenna (use ANT socket) or composite (trough AV).

Do you also get a picture on a TV (from AV jack input) when you use your LT in an IFU? That would be interesting to know....

Ok, thats good to know.

Looks like I have a fucked up TV part...since it doesn´t even show noise on my all new modded screen as well when I switch to TV.

No pickie with AV input as well  :-k
