It sounds as you desribe, the vertical output IC and or the b+ feed capacitor off the Hi voltage transformer feeding the vert. IC its required voltage. Not a really hard job to replace, but not for a handi person to do. This should be left to the professional, as there are no user serviceable parts inside this set and with the HI voltage and the safety issues its best to call somesone to assist you with this repair. Good Luck

this is a convergence problem not a reset problem. go into the video menu and look for manual convergence. you could try auto convergence if your tv has it but i think you will have to go in and manually do it. just line the colours insync with the white bars and this will clean up the colours on your entire screen let me know if this doesnt work but im pretty confidant it will

I had the same problem and HP has been very helpful, try calling this number 877-917-4380 ext. 79 and be firm tell them this needs to be fixed. They are sending my second replacement part and said they will keep sending parts till it works, this tv is almost 3 years old.

Just to update this issue, HP has now agreed to replace my plasma free of charge, they dont know how to fix it and after a couple of tries they gave up and I'll get my new one next Friday. For all of those trying , keep trying and don't give up, don't take no for an answer. Comment posted on Feb 04, 2009Just an Update here, My new plasma arrived on Monday free of charge, no shipping, no money at all, works like it did when new. Call HP with the number listed and let them have a piece of your mind, you will get results.

This is an easy repair if you've ever soldered and would not be too costly for a repair shop to do it for you. The problem is a bad Vertical Output IC (usually mounted on an aluminum heat sink with the part on it labeled LA78?? ) and 1 or 2 bad capacitors. Some times you can even fix the problem by re-soldering the contacts of the IC- To find the IC follow the 4 wires that come from the Yoke (which is a contained coil of wires slipped over the neck of the picture tube(s)) back to the board. 2 of the wires go to the horizontal o/p and 2 to the Vertical o/p the thinner gauge wires are for the vertical.
