Mis-aligned color
The color on my TV is not aligned very well. For example, it's not centered ontop of the luma signal good. See the mario bro's coin symbol at the top.
http://img.photobucket.com/albums/v3...ragon/tv-1.jpg Once again, no POTs to adjust this. Is this going to be caps again? Ugh, I just fixed the flyback, I don't need to be tinkering with this chassis, I just want to enjoy it. |

Red smear = weak crt lots of the time

Did it look like this before you replaced the flyback?
Perhaps maybe the yoke assy. is loose? Could also be that the convergence rings may have been disturbed. Usually there sealed with some type of glue/paint.

Given the age of the set ... weak crt

Can't be weak CRT and it did this before flyback. On a greyscale image no problems at all.

Always a crap shoot diagnosing from a screen still but sure looks like a weak crt and static converg appears off as well. Of course as others have posted could be other probs.

I see all color smeared - blue into green as well as red into blue. I don't trust the game console. Does it look this bad on a better source like a DVD or cable? Have you tried to see if it changes with fine tuning?

Happens on all sources. I tried fine tuning and while it helps a little doesn't fix it all the way. If for example I hook the tv up to the Lima output of my DVD player for a pure monochrome image there is no color bleed. This leads me to believe the CRT is fine. I'll try and get a cross hatch pattern tonight for convergence.

Hmmm- delay line problem, or misalignment somehow?

Could be an IF alignment issue. did you try channel 4?

The smear from a weak crt never shows up on the greyscale only on colors smeared to the right and red is always the worst.

Really? I thought they did. On my hitachi on a greyscale screen at high contrast it bleeds.

if you find it is a weak crt, sometimes but not always, you can set for a b/w pix and adjust the color and tint slowly forward and get a nice picture ... a case in point
in front of me is a '96 production RCA 36" set with a weak crt ... with the remote and the aux controls i adjusted the set slowly advancing the color to ~ 75% and keeping the tint weighted heavily towards green ... now have an excellent picture how long will it last? a roll of the dice it is ... could be 15 min ... 15 days ... 15 years mine has lasted several months with no sign of degradation |
