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.
Comment posted on Jan 24, 2009Just 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.

Samsung plasma TV model #pn42b400p3dxza problem with no image. The TV has sound but no image. I've tried using other components on the TV like RCA jacks with a separate TV digital tuner. Thank you


The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Check whether Va & Vs voltage come to the display panel, from the main power supply regulator board. If not, the SMPS board [power supply regulator board] is faulty.

I have pioneer plasma tv about 6 years old. I turned the power on, sound but no picture. Do you think it is worth fixing?


no
plasma tv units consume considerable power and the latest led units don't so for the extra cost of a new unit , there will be a power saving over the years
