Hitachi 26LD2550B (17MB22-2)
« on: June 19, 2009,03:43:02 »
I have this set on my bench, the customer said it had a very dark picture when switched on.
Tested inverter board that seems ok, when i switched it on the from led is flashing blue on/off, if i press a button it will flash red for a second, i am suspecting the eeprom chip is there anyone that can tell me how to check this or get it reprogrammed as i do not have any dumps or programmer, any help would be grateful, Many thanks in advance.
