45" Pioneer projection tv model:SD-P4571K/KC,year:Nov 94.Intermittent
flashing picture with no audio and lines running across screen (left to
right) while problem present.When menu button is pressed picture and
sound come in perfect but customer can't watch with menu screen on as
it's obviously annoying.

Eventually after about 15 minutes or so picture looses severe
convergence and the bottom of the picture curves upwards and the top of
picture is curver upwards as well.

When tv looses convergence menu can longer be accessed and channels
cannot be changed only volume and power but no OSD bar for volume.I can
no longer access RCA input jacks.
When tv is first turned on from a cold start I can access RCA input
jacks with perfect picture & sound but when switched to tuner input
picture begins to flash.

I replaced the 3 electrolytic capacitors in the seperate IF block:

C22=0.47 uf,50v
C26=0.47 uf,50v
C05=47 uf,16v

I also resolder IF block,tuner and lots of parts on many boards,I don't
repair projection tv's nor do service/pickup calls but this one is an
exception.
Anyone have any common repair tips for me?.Thanks in advance.
