Hello I have a HP PL4260N no picture, what can I do to trouble shoot?

I have the same problem with my HP PL4260N 42" Plasma HDTV serial # CNH6141988, model # CPTOH-0602. I have perfect sound and can change channels still with sound but NO PICTURE. I am a consumer with a question that need the advise of an expert.

You do not need a "picture tube" whatever you may mean by this.

Here ya go

surely there is problems with the lcd controller... you need a qualified technician to check the power consistency in your lcd controller.

Its probabaly one of the three boards, X-SUS board,Y-SUS board, Z-SUS Board.

If it is not a loose connection (internally), it may be most probably related to your picture tube. Check it out and if found faulty get it replaced. If your are in any warranty period (I don't think so since it is 3-5 years old), don't do anything and just inform them, or else you will loose your warranty security.

most likely scan drive and upper and lower buffers

throw it in the garbage.
