Turbo Express DEAD SCREEN...Working towards a cure.

[ctoomey]

I thought I'd start a thread for this...

On a dead screen unit I have, I connected the TV Tuner and a BAD picture (looked like a film negative) with static etc actually showed up. I then turned off the tuner and the game screen came on. Again though, it was 'streaky' and looked like it had a slow refresh rate (non tech terms I know) as everything was blurring pretty badly. It seems like the tv tuner signal actually 'jump started' the screen and now it will work (terrible picture though) every time I fire it up.

I then took another screen (basically the entire 'top half' of a TE) and plugged it into the dead screen unit and it jumped to life.

So, it looks like the screen issues are in the screen as opposed to being a capacitor issue etc...Not sure where to go from here with it but thought I'd put this info out there if others have also been tinkering to find a solution to this issue.

Very interesting, I made a thread months ago about ways of fixing TE screen problems. Thanks for this information.

Hmm, I thought I made a seperate thread for it, but I guess I didn't. You can find the posts here https://www.pcengine-fx.com/forums/index.php?topic=1546.0 .

So I am assuming my screen is shot since when I plug in the back of my TE to another unit with a working screen it works fine. The 'Broken' unit is streaky and looks like its not refreshing quickly (non techie I know)....Any ideas? Thanks
