My experience with a Haier Plasma 42EP24S is that they have weak software
chip that goes bad and can cause a number of symptoms from picture with no sound, will not recognize
video inputs, or my current problem tv turns on and off irratically. This is the second time i have replace this chip, which is the socketed chip on the vga/component/dvi input circuit card. Last time i had this problem i ended up fixing it myself because sears took over 3 weeks and still could not figure out the problem. I am working on obtaining this chip, probally get about a dozen so if anyone thinks this may fix there problem as well i my have some for sale.

Not necessasary to change 3 boards.
I dont now your situation but I would check before replacing 3 boards this unit has been upgraded preveously?If this (42EP24S) upgraded previously you dont need to replace 3 boards.
Most probably it could be the problem with Y-sustain..
Good luck
