    This was very helpful. Do you know how many 1.8 ohm resistors require repair?

This set is made by Hitachi and uses two Stk392-110s for convergence amps. Usually when the amps fail the 24v line triggers the shutdown circuit. Replaced both Stk's and any or all of the 1.8 ohm resistor in that circuit as needed.

    Anywhere from 1 to 12 resistors - and btw you can also us STK392-150 Ic's for greater reliability.

Its most likely dead pixels. This generally happens over a course of time. If its not too big that it irritates you, you could possibly let it go. Otherwise, it could call for a service job.

This set uses two convergence packs that go bad and take with them a resistor or two. You will need a repar shop to get it fixed. If it's over 10 years old, I would suggest getting a new HDTV set as these sets can start going downhill fairly rapidly past this age. If that's not an option, the repair could run over $350 IMHO.
