atari 2600 light sixer display glitches

[cypher007]

ive bought an Atari 2600 light sixer.

 

ive then recapped it, the output from the modulator was very bad, recapping didn't fix this issue. I wasn't to worried as I was going to fit an S-video - Comp-video mod.

 

I bought said mod from a seller on ebay who was selling this:

built it and connected it up and I'm finding on a lcd some sprites look wrong, the colours look ok though. I might post a vid to show the issue. essentially on say asteroids the image is very dark and the asteroids have a fringe. in defender the enemy sometimes seems to de-interlace.

 

anyway I tried the same console on my parents old (2003) 32" JVC 1080i capable widescreen crt. it was slightly better but I still find in defender some of the enemies and the main ship disappear occasionally for a second.

 

is It because the old modulator is still installed? or has my TIA got issues? or is the lcd and the crt too new? I did turn all the digital tweaks as low as I could on the crt.

 

 

P.S. I'm loading PAL games via a Harmony Encore.

the only other strange thing is the Harmony Encore menu comes up in black and white then after a while turns to colour.

 

I ordered the Harmony direct from USA could it be I need to change the firmware to PAL?

[cypher007]

anyone?

You probably do need to change the firmware to the PAL version.

 

The 2600 will always look wrong on most LCD's.

 

The CRT description is hard to say because everything disappears in Defender all the time normally.

i thought if I used a PAL rom with the harmony it would display in PAL. and only the menu would be NTSC.

 

why would the console start in black and white then switch to colour after a while?

[cypher007]

ok managed to pickup another light sixer this week with some carts that's been in a shed for several decades I would think.

 

fired it up and noticed some differences. asteroids is mostly the same on the lcd using an original asteroids PAL cart. but the new sixer is colour on first switch on, whereas my modded sixer flickers into colour after some seconds after switch on.

 

after reading some info on here could it be the modded sixer has a failing colour crystal? or was this part only on NTSC systems?
