Question about Hitachi 43FDX15B 43" Rear Projection Television

1 Answer

43FDX15B No picture, Power light stays on

43FDX15B 43 in. Rear Projection Television
I was having problems with the convergence IC's so I replaced them, reinstalled the board and the TV worked great! For about one movie...

After that first movie I turned off the TV and when I turned it on again the next day I had no picture and could not get the TV to turn off at all.

Since this was the original problem, I ordered another set of convergence IC's took them to a repair shop to have a technician replace them, he said the convergence IC's were fine so I reinstalled the board.

The red power light stays on, I get no picture, no sound... nothing other than that little sound it makes when you first turn it on/plug it in. If I unplug the set, wait 30 seconds - two days and plug it back in it makes the same sounds it used to make when you first turned it on but nothing beyond that.

Further inspection on the inside shows one Red LED next in the center right next to the back of the TV glowing. Four Green LED's (behind the red one - closer to the screen) and these would be on the board to the left of the convergence circuts. On the power board (where the power actually comes in from the wall there is also a Red LED... all LED's are glowing. I checked the board connectors and no wires are touching on any of the 4 connectors bridging to the convergence board.

Any thoughts?

Thanks, Pete

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.
