VESTEL 17MB25 blinking LED, not switching ON

<< < (3/4) > >>

gatis:
I removed C900 (12p/3kV). No any change :(

jimca007:
have a read at this see if it helps

jimca007:
check around page 10 thats most of the power and protection components
Just out of curiosity are you sure on the 17mb25 bit ( the number of the main board ) as the manual for a 25 shows its powered by a inv/psu combination an IPS unit not 12v external ?

gatis:
Thank you for schematic! I used same. Yes, it is definetely a 17MB25-1 board. That printed on the board. May be original VESTEL TV using something as you told, but this is MATSUI M16LID709. As I found same look has ALBA LCD32HDF. How fare I understanding protection circuit so everithing seems ok. PROTECT all time in low level, but PROTECT_PANEL in high level and there no any changes at all. Here no any another signals which used for power failure protection detection.

on page 5 you'll find teh inv. and dimming circuits check there , you could try a hard reset of the eeprom. Solder a wire onto pin 5 and another onto pin 6 join then , start up . unplug from supply. disconnect wires , reassemble and switch on as usual.
