As posted for a similar problem:
This is an issue with IC 803 on the Z board. This is a 3.3 V regulator that supplies this voltage to the slot card cage. Most input boards use this voltage EXCEPT the component board which is why it keeps playing along whike the DVI, HDMI, or composite signals will cut out after warm-up.
This is a surface mount multi-pin IC and is a bit tricky to replace.
The entire board is PN# TNPA3198xx with suffix determined by what model 7 series plasma you have.
This was a problem from around Nov. 2004 to Mar. 2005

Since the set is only 8 months old, it should still be under warranty. This may only be an internal connection problem, but opening up the unit will void the warranty. I would suggest that you call for warranty service. This is a problem with the set and has nothing to do with external devices or interference.
Keep us posted.

it you have a repair skills you need to open the TV and make sure all the ribon connectors around the circuit boards are proper connected
and if all seems to be ok, the DG board will need to be replaced.
If you dont have any repair skills I would recommend you to take you TV to a repair shop since this is complex repair

Your power supply board is dead, u know basic electronics’ and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
hope this helps...

The picture turns green if the component input cables are not connected in. Can you confirm that it is what you are using when you get the green picture? If yes can you please clarify the connection sequence of the RBG cables and the repective ports like Yb, Pb,Pr?
