Question about Hitachi 46F500 46" Rear Projection HDTV-Ready Television

2 Answers

Magic Focus Hi, I saw that you responded to someone else who is having a problem with their magic focus. I have a Hitachi 46F500 projection tv and the blue color is off.  It looks like it is drooping in the middle of the tv and across the bottom of the screen as well.  I tried using the magic focus but it stops when it gets to the blue and then flashes a number 5 in the lower right corner. I'm fairly certain my father will be able to fix this for me if he has some instructions.  Which parts would I need and where would I be able to get them?  I live in Canada in the Toronto area. Thank you!!!!!

Sorry Kristin Ann I haven't log in here for quite a while....

I guess you've bought a LCD already LOL...

Anyway Slinteriors were right, most likely the Blue convergence IC is dead and because the IC's (BLue & Red) are working as a pair it is always recomended to replace both.
To do this you will need some soldering skills and after replacing them you might need to align the digital convergence through factory service mode.

Check the resistor in front and back of Convergence ICs. STK392-110s. the ICs might need to be replaced also. Look for poor solder connections also.

Blue lamp is not in focus


Try adjusting the convergence. If it won't move see below- (or hitting Magic Focus for some Hitachi’s)

This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$400 Be sure to vote/rate me if this helped Thanks!

No picture, have sound


Dude, you dont have the same problem thanks for junking up my post.

Ok, so I have replaced the SUB power assembly and the SUB Defconvergence board, picture looks decent however magic focus just blanks the screen out and cannot adjust manually does the same thing.

Is there a way to enter the service menu and initialize the magic focus functions after servicing.

It must be using the saved ROM settings, but it wont let me adjust anything convergence wise.

Thanks,

Joe
