This fan is to cool down power supply temperature and even in standby mode power supply works.

Cooling fan won't turn off.


this set has more then one fan; one fan will run all the time to cool the digital circuit board---if it is the actual LAMP fan then you have a problem---the digital fan is very small and not located near the lamp.

HITACHI 50VS810 WON'T TURN ON. .


If the set comes on momentarily, see if the lamp fan is turning. If not , the fan is probably bad.
Hope this helps,

Hitachi 43fdx20b Need capacitor but i dont know which to buy!!


Hello Soleftright,

I have CK24 as a 1000pf 50v cap. Look at CK25 it is the same value as CK20 - CK24. Were your convergence ICs STK392-110s? One side of the cap goes to pin 14 of the (IK-04) IC and the other to ground.

I hope this helps
Thank you,
