| Have found that the problem is around ICX01 ( TB1203AP) .That is a DAC
that
| controls the brightness, contrast etc.All the input pins on the jungle are
| low,have lifted the .01 caps that leak. (c621,c623)
| Can't find a pinout of this chip, not listed on Toshibas site Google has
| one hit( Japanese)
| anyone have any info on this?
| Note: can sub voltage to brightness and contrast lines and get a B&W pix.
