Question about Toshiba 50H82 50" Rear Projection Television

1 Answer

Toshiba 50H82 blown fuse f470

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.

    Installed power/def board and everything works great. It even took care of the zig-zags on top of the screen I thought were related to bad caps in the hyper board.

    hi smellycat, I actually ordered the board from Sears Parts just in case I had to have them finally come and fix it right. They get there parts from PTS Electronics (ptscorp.com) so I guess you could order from either one for about 190 delivered which was a lot cheaper than the $300-500 quote I got to fix the tv. Its actually pretty easy to install. Label all of your connections real good! The anode cables(look like spark plug wires) are a little tricky, roll the boots up, give them a little turn and pull. The board also goes under little tabs on the left, make sure the board is under them before you tighten the screws. Good luck. Let me/us know how you made out.

Have a Pioneer stereo receiver, Model VSX-4400 (made in 1989). It works just fine. My question is: will it work with high def? Thanks!


No. It does not have the required inputs and output connections nor digital decoding to support any hi-def formats.

Picture problem on Panasonic Plasma tv


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.)

I have a 50" hitachi rear projection tv, do i need


rozmyers,

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.

Thanks for using FixYa and for the great rating. Please consider a testimonial.

How can I get my Denon 2106 to play through my television? I'm not sure what's happened. I feel like I have the cables hooked up properly. It's worked for years. My stereo plays, so it's not the speakers....


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.

Can get analog stations recorded but not hi defination


Hi, unless the VCR/dvd recorder is hi def then you won't be able to.

Hdmi connection is hi-def, I think you can have a hi-def signal through composite, but it's your recorder thats the problem, it cannot read the number of line a hi-def signal has.

I have just found this.

No picture - only sound


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.

Playstation 3 not working with older model Pioneer AV receiver


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.

Hope this helps.
