Question about Toshiba 57H82 57" Rear Projection Television
The tv takes about an hour to boot up and show a picture. if we try to plug and av source in we lose the picture again. we took out the board with the inputs and looked it over. everything looks normal, except connections in the corners look slightly burned. they look like a wire with a blob of solder in the middle. i dont know what they are for but the symbol its covering has a circle in the middle so it's supposed to be there, it just doesn't look like it works anymore. any help would be awesome. thanks.
I have a possible answer---are you getting noise lines across the screen for the first several minutes that would eventually clear up and give a picture or something else?

The STKs are common and if you have an experienced electronics tech
around they can replace them for much less money but the tech must have
advanced soldering and IC exchange experience.
The STK ics, two of them, can be purchased on line for around $20 to $40 each.
Partstore has two models available - one for around $40 and another for around $55.
The part number is STK392-110 and if you google you can find them for as little as $6/each but I don't recommend the cheap ones as they are not reliable.
It takes a good tech around 3 or 3 hours to take the old ones out and solder in the new ones. Also, it is likely one or two resistors are burnt and will need replacing as well.

first of all take the board out and back sure all the pins are soldered and that one didnt get pushed up out of the way.
then check for solder bridges where you would have solder more than one pin together.
then check the resisters in the circuit that they are all good and then check to make sure everything is plugged in correctly

I have direct TV and I have the same problem also. It happens about 1 ot of 8 times. All I do is turn off the satellite receiver for a few seconds and turn it back on while the TV is left on. It works everytime. Don't drive yourself crazy with repairs and the like. It is just one of those things.

That happened to me before. I was watching TV and all the sudden it would just turn off on me. The power switch had gone bad and I had to have a new one put in.
