NO RED COLOR ON A 43FDX15B HITACHI 52


3 reasons for this.

1st reason the fluid is contaminated and thats why u dont get red.

2nd reason no red drive possibly due to a bad colour driver on the base of the tube neck.

3rd reason the tube is out.

Just a thought, but check all of the pico fuses for a blown fuse. The pico fuses look like a small yellow resistor. Some Hitachi's are famous for having a blown hi-volt ceramic capacitor and a blown pico fuse.
I think the red led on is a short protect indicator, but I could be mistaken.

Hitachi 43FDX15B has a red tint...


This can be caused by a few things. The red crt/picture tube is going bad, which it would have to be replaced, tube can cost anywhere around $195 and up, if it is available. Another problem can be a bad transistor or IC on the red crt circuit board. Either way it should be taken to a repair shop. The average cost for repair could be over $300.

Power light stay on


Sounds like you may have a sticking Relay S901 on the power board. Tapping the Relay may Make The Light Go On And Off. The relay part number is FJ00142 if you can find someone to work on the set for you as it would involve soldering in the new part. The number on the relay may be ALKS329 with the former part number being the Hitachi Part number.
