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.

My 57" Toshiba projection TV recently started having picture problems. The picture is distorted and wavy. The picture on the PIP screen is fine. is this a common problem and is it fixable?

First bypass the cable box and hook the tv directly to the cable to see if the problem goes away. if the problem persists you possibly have a bad input board.

Toshiba 50H72 problem plz help!

ok well both of you have had the same problem i did... to fix the picture problem check the circuit board pd0074 its the yellowish looking one next to the green one which has the ic's on them... ok on the pd0074 board look for fuses f470, f850, and the f851 to see if they are blown the f470 is what turns the tv on and the f850 and f851 are what protect the convergence ic's chances are they are blown.... the sound i don't know how to fix that problem but i would check all the fuses on that board to find out if one more is blown that what i did but the only thing is that i could get the actually fuses for the tv i was told by a tv repairman in my town to just take 2 wires sodder them on to the fuse and take a glass fuse and put electrical tape around them and it worked like a charm... so i hope this helps you.... the most i spent was 30 dollars for the ic's and the fuses all together and i was quoted at 450 to do what i did myself

No video on a 50H82 Toshiba Projection

If the screen is lit, then there is high voltage. If there is no video, and the screen is lit, then there is a loss of video. The fault can be anywhere along the main video path before it gets decoded in to the red, blue, and green compositions.

If the screen is not lit, most likely there is a high voltage failure, or there is a failure in the bias supply for the tubes.

When there is a loss of high voltage, this can be from any of the components in the high voltage area. Some of the main things that go defective are the flyback, high voltage multiplier, and various other small components.

Have you considered to replace the set with a good Plama or LCD set? This repair may end up being on the expensive side.
