    i have the same fault unit is ~2yrs only the orange light is on it must mean something can anyone help please

    I have a Soniq PT42SH plasma that turns it self off every now and then and the power LED goes orange. If I turn the TV off at the power point and then back on, it comes back on. It may stay on for a day or only 30 minutes before I have to do it again. I found a forum that had info about a $12 part that needs to be replaced (something to do with the power) and it will fix it. I have no idea what this part is but I would like to know so I can get my TV fixed ASAP.

Soniq 42" plasma, model pt42sh

Yes the problem is the power supply.You can do replacement of power supply if the power supply you replace is the same to the original power supply of your television.If did not the same there's a conversion in the wiring, it may be difficult for not technician and have no knowledge in electronics..Thanks..
