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

1 Answer

No picture, have sound

My Hitachi 46F500 has no picture but does have sound.

I have unplugged the power, waited 10 minutes and even tried different inputs from devices - nothing.

The sears repair guy came by and estimate $1100 to fix....

    Sound is perfect, but Picture turns into horizontal blues/reds. Will return to normal after being left off for some time. Only occurs when watching Video Input connected to HDTV Cable Box. Picture is operable when switching to other Video Input connected to split cable into VHS/DVD unit. DVD viewing not affected. Cable Technician thinks it's TV's converter.

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

I have a 65" hitachi rear projection. I installed


This sounds like it is due to the lamp on the projector going bad. Replacing the lamp should fix the problem. Contact Hitachi to find a suitable replacement lamp.

SOUND BUT NO PICTURE - Philips 42PF9631D 42 in.


Unplug the box's power cord for 5 minutes and wait for it to reset, plug it in, wait another 3 minutes for the box to reboot, then power up the box. If that doesn't fix it then you might have to call your satellite/cable company.

Hey own a 2003 hitachi model #46f500. love it a lot,but has a tint of red on screen. when dark movies are on gets real dark. when its day light on tv it looks great. info please


It sounds like the CRT tubes are weak which will not practical to replace them.

But try to clean the dust on tube first and if it doesn;t help do this...

Caution!
Risk of electric shock, focus block carries 4 kilo votls, do at your own risk or DO NOT do it at all.

Just try to adjust the screen voltage adjustment to brighten the 3 tubes from focus block, to do this you have to open the back then let the TV run for abut 10 minutes beofre adjusting, each tube has its own screen voltage adjustment, read the label make sure not to tuch the focus adjusment, do not crank up too much make it very slow or your TV will show retrace lines or it will shutdown.

good luck.

No sound on hitachi 53sdx01b


The first thing to try is rescanning the Freeview channels as it may just be a software corruption...if you have the option of "1st time installation" pick that.Also let me know if there is any buzzing sound coming from the tv..
