Question about Hitachi FDX Series 43FDX10B 43" Rear Projection Television

1 Answer

Hitachi TV 43FDX10B has yellow line with blue curve line above it

The yellow line is in the bottom half of the screen- it goes about half way across the screen. There is a blue curvy line (like a wave) right above it. I've tried adjusting the color but it doesn't go away. This has been going on for about 2wks, now the entire screen pic seems to go bonkers. Everything turns to a green tint then yellow and back to normal, few minutes pass and it does it again. I have no clue what is going on. If you can help please be very detailed and speak in non technical terms (if possible).

It sounds like your convergence ic's are messing up

They have a kit for this tv it is available through local parts distributors
If you can't find it locally just Google HITACHI CONVERGENCE KIT

If you are not good with de-soldering and soldering do not attempt this repair. Remember to replace all the resistors in the kit

If you are not sure about doing this repair you should have your local tv guy do it for you

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together convergence repair kits for most models.

The kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, etc. Everything you will need to do the repair yourself.

Green horizontal lines across screen


try adjusting the green screen control. remove the front bottom panel of the tv by removing any screws holding it in place. gently pull of the front panel, there are gromets holding it in place, you will be able to gently remove the front, just make sure you get all those screws. now reove the small wodden or plastioc panel. now you will see the screen/focus assy. check to see of the screen controls are the top 3 or bottom 3. adjusted the center screen it's the green one, the other 2 are the red & blue. it is best to adjust in a dark room where the lines will show up easier. good luck
