Pioneer rear projection convergence [Revisited]
I posted a while back about repairing a Pioneer rear projection TV that had
a convergence problem. I've replaced the IC that was recommended to me. The good news is the TV still works (remember I'm no TV repair guy); the bad news is the convergence is now way off - far worse than before. This is now what it looks like: http://www.ratsey.com/ti2/pioneer.jpg Am I going to have to resort to professional repair for $$$? Remember this is an 8 year old TV that's already been replaced by a plasma and has been retired to the basement where I was hoping for a few more years before getting an overhead projector. Any advice? J. |

Did you mark all the plugs going to the convergence panel? It looks like you
may have gotten the yoke connectors swapped around. Make sure rhe yokes are connected according to CRT, Red on the red crt, etc. -- Jammy Harbin J & J Electronics, Inc. 227 S. 4th St. Selmer, TN 38375 731-645-3311 "Jens Ratsey-Woodroffe" wrote in message et...

I wrote on the connectors which they were when I disconnected them. I'll
check again, but I'm pretty sure I got them on correctly. By yokes do you mean the connection blocks? "Ampdoc" wrote in message . .. Did you mark all the plugs going to the convergence panel?
