Re: Toshiba 40L3433DG - very hot Q301 on PSU board
Vcc on U300 (NCP1380D) is 18,3V.
Vgs is max 3,5V.
Voltage drop on R320 (0,47R) is max 0,08V.
Any ideas? :/Leave a comment:

Toshiba 40L3433DG - very hot Q301 on PSU board
Sorry for my english.
Toshiba 40L3433DG, Vestel 17IPS20R6.
TV not working, only led blinking. I find shorted Q301 on psu. I change it to similar. I don't find any other damage. Now works fine, picture are very good, but Q301 is extremely very hot.
Where look for other damage?
