Ah it's the sx that has power supply issues? I'm not fully aware of the differences between them all. Is there a good resource that breaks that down? I just know that Toshiba used ELNA caps in a lot of their computers, and ELNA caps make a mess.
Is the IC corrosion internal, or is it possible to clean and resolder the old ones? I do tend to see more "bad" plasma panels with these sort of issues than good ones when they show up online unfortunately...
I don't think there's a clear list of al the models. But from what I have learned collecting Toshibas these are the models that have those unreliable PSU's with the leaking caps. I tend to call the issue the "red light of dead" because most of the time even after a recap the red power led will keep blinking without turning on.
Unaffected: T1000, T1100, T1100+, T2100, T3100, T3100e, T3200, T3200sx, T3200sxc, T5100, T5200, T5200c
(of course some of these have other non psu related problems)
PSU problems: T1200, T1600, T3100sx, T1000le, T1000se, T1000xe, T2000, T2000sx, T1200xe
As a rule of thumb you could say that all the models with a user replaceable battery are affected by this.
Thom aka Fust reverse engineered the T1600 PSU and made a troubleshooting guide.
The power supplies are all similar enough that you could use this for most of the models
