Red Lines On Screen of Hitachi 43FDX01B

Help! On the screen of my TV (Hitachi 43FDX01B) there are these crazy horizontal red lines. Some of them are crossing at the bottom of the screen and then towards the top they curve upwards going from left to right. It happened once or twice already and it fixed itself, but now they're not going away.

I also have the same problem. I've found that you can adjust each color of the screen by removing the speaker cover. Underneath you'll find a piece of partical board. Remove it. Looking at the front of the T.V. from left to right you will see the projector assembly for each color, red, green and blue. There are about six levers that pivot around each assembly. There factory settings are marked with white paint. By turning the ones on the red projector only you can manipulate the reds alignment on the screen. I don't know if it will work yet. My wife is the middle of adjusting. If anyone has a better solution please post it. I love my T.V.

Convergence lines on the Hitachi 43FDX01B


Download this manual:-

http://schematicsforfree.com/archive/file/_newly_uploaded/Hitachi_DCAM_Manual.pdf and do the Red touch up on page 63. However I would read the rest of the manual as well so that you get the full understanding.

If you still cannot converge the Red then you will need to replace the two Convergence IC's and associated resistors. Details of how to do this are here:- http://www.digitalhome.ca/forum/showthread.php?t=21847

Remember that there are VERY HIGH VOLTAGES present in an RPTv even when it is disconnected. So disconnect it from the mains for at least 4 hours before you enter the set, this will give time for the high voltage to discharge.

Good luck!

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
