The red color is not aligned anymore on my Toshiba


This model uses two of the STK-392-110 convergence IC chips.

Both of them need to be located and replaced--along with any of the several 1.8 ohm protect resistors around them that are bad.

The hard part in this model is getting at the chips--I can tell you what is involved if you or someone you know can do the repair.

Considering that total parts cost if you buy the chips on Ebay (I can tell you the best seller there) will be under 15 dollars plus shipping, if you can do this you can save the set and a LOT of money.

Most shops are going to get 300 or more for this repair.

Toshiba 42h81 replaced IC's now flashing red light and no picture


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

Red line


Need convergence IC's and probably several resistors that have changed value. Seek professional help, someone who uses ORIGINAL ic's, not generic or knock-offs
