 |
|
I got a Mitsai TM 1401 - Its a Chassis F 11
The problem is that I get a blank screen (No color no image and no OSD).
(I can change channels , have sound, brightness, ...)
FBT seems to be ok.
It had L602 burned out (Hor. Def.) but now is ok.
Can anybody help me with this one? |

More news:
Probably isn´t TDA 8361 ( I´ve got signal out via SCART) and the TDA 3653 it´s OK
But i still get a blank (light grey / no color / no image) screen.
Could it be the Flyback Transformer ( it apears to be ok) ? or the driver ?
R607 (5 Ohm 5W, that feed the FBT ) seems to over eat.
Come on guys, give me a hand. |
