My Toshiba 50H82 has worked great for the past 3.5 years until I recently hooked up an old Voom High Def receiver to get over the air high def. Picture was beautiful but the tv would act up sometimes on 720p, the
screen would turn bright white and might turn off on its own if I
didn't turn it off quickly. But no problem with 1080i. I turned the set
off one morning when the picture had turned all white and after that I
had sound and no picture or menus also no glowing filaments . I found
fuse f470 blown and soldered on a temporary inline fuse. This fuse may
go to the flyback transformer but I'm not sure. Now the set turns on
for a second and then shuts off with a blinking power light. I have a
Power/Def board on its way but I'm almost afraid to install it in case
its something else that might take out the new board. Could using 720p
resolution put extra stress on this tv? Any suggestion on what could
have caused this? Also my tags fell off the three anode leads, does it
matter what order they go into the transformer? I live to far away for
a service call. Thanks for your help.

It looks like you are saying standard definition pictures do not cover the screen like HD pictures do. Standard def is formatted 4:3 and high def is 16:9. They are not the same so your high def screen is made to display the not as tall but wider high def picture. In order to fill the screen with the taller and not as wide 4:3 aspect ratio std def picture you must tell the TV to stretch the picture or otherwise fill the screen.The TV will have controls you can exercise for this purpose and you can set it up to always show std def in a particular manner. The alternative, if you want the standard Def picture to look true to form, is to view standard def in Letter Box form. It's appearance will then include black panels on the sides of the picture. So the problem is not with the TV but in accepting older format pictures playing on newer format displays (TVs.)
You do not need a high def receiver, your unit has an ATSC tuner which is the same thing. You do need to hook it up to a high definition signal. You mentioned that you have satellite. Call your supplier and order the high definition channels if you do not already have them on the downlink. They should be able to tell you if you have them or not. They should also be able to tell you which channels they are (normally the higher ones). Once you have a high definition feed you will have the best picture you are going to get with todays technology.

Hello: If you are trying to get the sound from the TV to come through the receiver to your speakers and are hearing nothing, I had the same problem. For some reason, and I have the question posted, the sound level requirement is much higher for the TV. I turned my receiver up to +2 decibels and the sound was there. However, if you play high def channels through the receiver, the +2 will blow your ears off. My new problem is why does the regular TV need so much volume on the dial while the high def channels only require the lower sound level. It prevents you from switching from regular to high definition channels. So, in summary, the sound is there, just turn the volume way up.
Ok, on a hi-def tv, you must have a converter box capable of receiving Hi-def. If you are using a converter box from a satalite or cable tv service, try getting a Hi-def box. Also try hooking a vcr or dvd player to the tv in the non high def ports to varify that this is the problem. If you have any question please let me know, I hope this helps, good luck.
If you have set the component output on the ps3 for high def,ie 720p or 1080i and do not get a picture it sounds like the component input is not high def enabled on your amp,change the setting on ps3 to standard 576 output,or put picture into tv then sound into amp if you want to run 720p or 1080i.
