My 57h82 has no picture of any kind but has sound. Menus won't show up or anything. A similar problem happened in 2005 and the shop replaced a 2 amp pico fuse. Right before my video went out this time the picture went all white and then out. The power light still functions so I know that there is power, that and the fact that there is sound. My problem becomes that I don't know where the 2 amp pico fuses are or which ones to replace. Would love any help. If it helps it was about an hour before another Florida thunderstorm but my TV was connected to a 1200 joules surge protector. If you happen to have a copy of the service manual that would a big help to or if you can explain it to me also awesome.

Re: 57h82 no video
Your set has pico and micro fuses soldered in ( various locations) depending on what circuit B+ supply is being "watched"...the amperage can vary from 2 to 5 or more...
Went all white, then no pix suggests you lost the 200volt
source B+ that goes to the RGB pcboards = one on end of each CRT.......Some websites offer SM's = search your Model # then service manual.........HTH>...........T.

This sound familar. it sounds like the hypermodule problem. idealy the best way to repair this is the past was to replace the hypermodule. but they are hard to find. Next idea is to repair the board. the way to do this is too replace 11 micro capacitors. But soldering these can be difficult and labor intensive. if you get a tv shop to do this find a qualified tech. prices differ on average this repair should cost about 400.
if you type in "toshiba 57h82" in a google search, the page should show you a list of lamps of veriuos stores with variuos prices. Now to change it, www.youtube.com can have a great resource of information about how to change the lamps. In youtube, just type in DLP lamp replacement. You may not find one on your set, but after whatching a few of the videos, you should have a working knowledge how to change it yourself. Just remember not to touch the front part of the lamp with bare hands. the oils in your body can cause premature damage to the lamp. Use rubber gloves. Cheap ones for a dolor store will work fine.
Pico fuses could be through out the board... And the service manual, if it has a parts list, does give the board designation for all the picos on it...
Although these are good pictures they don't show a great deal of detail... But picture 1 & 2 at the far left, above where the two sets of blue wires are plugged in - looks like a pico piggy-backed on top of another pico... Sometimes it's easier than desoldering the original pico just to piggy back them in this fashion - but it's not a good practice.
Start there and read the designation on the board... Then look in the parts list section of the service manual and find the others by their designation.
The good news is your set has a picture therefore is not an output transistor,the problem your set has is a signal processing problem,no video of any source is being processed,is just a different kind of problem and for that you will need the assistance of a servicer to diagnose,try taping where the cables conect to the tv if the set reacts the loose conection is close to that imput panel but if it does not be safe and call for help.
