Life has been busy so I've not been posting enough, but thought best to ask about this one in case anyone else has had similar issues and found a fix...

Craig sent me a TV-out cable awhile back, to look into repairing OutcaST for the tube; the cable only ever had black output on whichever TVs I tried it on (using SVideo, or using composite with an SVideo->Composite adapter). Jiggling the cable would flicker the TV screen to white for a millisecond, but thats all I coudl get.. black, with occasional white flickers when jiggled.

jr2 sent me a pair of cables that I received last week, figuring one out of the two must be good; the effect is only slightly different -- I get good solid plain black, with no white from jiggling; nice solid feeling connection, but still just black.

In all 3 cables cases, I can see _something_ must be halfway right, since the TV 'flickers' when I hit the GP2X tv out menu, so something is attempting.

o FW 1.2
o Freshly charged or new batteries, doesn't seem to matter
o Connect TV and cable to GP2X; turn on GP2x, wait for menu; in menu, go to settings and tv, hit enable; GP2X screen is turned off, and TV 'flickers' nearly imperceptible but remains black forever.
o The connector only goes on one way (can't put it on upside down as far as I know, so I doubt I'm doing that wrong.)

My assumption now is that it is my GP2X that has a bad EXT connector.

Anything I'm obviously doing wrong?

Any suggestions?

I suppose I could identify which pins are the TV, and see if theres anythign I can do with a multimeter to test it.. but not sure a TV woudl register; no oscilliscope handy :)

Perhaps the case plastic can get in the way and prevents a good solid connection without forcing it hard?

To get mine to work I have to hold it in and push it in and up (or maybe it was down)

TV Out fix

What symptoms did he have?

ie: With 3 tv-out cables, I wonder if its really a problem with the cable and not the 2x itself :/

I believe it was the "I had to hold the connector UP to get a picture on my TV" issue ... which is common from what I've read.

I don't know for sure if it would work for you or not, I still have to get an S-Video to SCART adaptor, so I don't even know if mine works properly or not :huh:


(Oh, and I'm moving this to the Help section, 'cause I'm an ass ;))
 
3 tv out cables not working, like i said, tried upgrading the firmware?

maybe cause i dont have a guru sticker by my avatar i appear invisible.

skeezix,

I had the problem where nothing would show up until I pushed in and held it straight. (to line it up squarely front to back with the GP2X)

I filed down a bit to engage the pins fully and used the paper to make sure it fit snugly.

I don't know what your unit is suffering from though.

Skeezix: We're NTSC over here and I think 1.2.X only had PAL support, but I could be mistaken, I know for sure that 1.4.0 allows you to select NTSC or PAL.... try 1.4.0 and see if that helps :)
 
Invisi-Paradox (and Hooka) -- I'll upgrde and see; it has ntsc selected, but perhaps its ignoring that; even at PAL I'd expect a picture, albeit a big messed up one :)

I'll give it a whirl; if still no go, guess I'll have to sort out which pins do which and find really fine tipped contacts for the multimeter :p

I usally insert mine after I have booted up, and wait to insert it into the tv after turn the tv out on (it would sometimes crash if I did it before).

I use 1.4 and think it would be best if you updated to that, or just wait for 1.5.
