The set was working fine and the it just stopped. When I turn it on now I hear two clicking sounds from the back of the set. No picture no sound no response from buttons on front of set or remote control. Any thoughts out there will be great
I had the identical problem (clicking sounds, no picture, but just the sound). I took Richdogg's advice above, but it didn't work out for me (lost money on the purchase of the part) - no offense Richdogg as I'm sure that was the problem in your TV. I later found out that the problem was with the Y-Sustain (also called Y-Main) Board. As with most parts in this TV, this is also made by Samsung and used in Maxent, Magnavox and a number of other 42" TVs. The part number is LJ 92-01256A (using LJ 41-02668A also give you the same part number). Hope others will find this useful.
I had this same problem it turned out to be the secondary power supply. This part is made by Samsung and used in Maxent and Dell systems. The part number is LJ44-00068A. It will range from $89 to $259.99 on Ebay. The Dell pricing is better.
swollen capasitors, replaceing will cost $500, so best to get another one, 42'' samsung will sell for about $800. the pn42a450
once a plasma has a problem, fixing it or not, more problems will occure, trust me, i am the flat pannel guru.
