My 2001 Toshiba 50WP16 50" plasma TV has, after 20 years of trouble-free service, developed a wierd fault in the last 14 days during normal viewing - with no loud bang or smoke or any other excitement.
Every 15-30 secs the right hand half of the image has a "glitch" for about 1 second before reverting to normal. The glitch has two forms and also depends on the aspect ratio setting (see photos):
Image input sources affected: Component, AV and S-VGA (but OSD not affected even when the underlying image glitches)
PC source is NOT affected, works perfectly in 1366x768 native resolution
Running Self-check mode appears to show a fault on the main board "D" with IC9011 showing as missing or faulty (see photo). However, as I can't find an IC9011 on any of the schematics or in the service manual, I can't be sure if this is a genuine fault.
Has anyone seen this kind of fault before?
My guess is that I need a replacement D board, ref.TZTNP010GYS / TNPA1901. These seem to be hard to find outside the US, so before I get too far down that road, I would really appreciate some sage advice from this forum on whether I am on the right track (or not).
Many thanks!

- 16:9 either a) a visible seam between LHS and RHS of impage or b) LHS image duplicated on RHS (photos 16x9)
- 4x3 either a) no image on RHS or b) RHS image offset by 1/6th with v faint ghost image in correct location (photos 4x3)
