Question about Philips 42PF9630A 42 in. Plasma Television

1 Answer

Screen goes black, picture grows over time but is dark

We have had this plasma TV for almost 3 years. We bought it from Best Buy without an extended warranty. We have had few problems over that time except for the screen often turning off for several seconds, then coming back on, which seems to be a frequent problem reported on these posts. Then last week, we turned it on and the screen was black, and the picture started to slowly grow from right to left, like mold growing across the screen. After about 20 minutes, 80% of the picture is visible, but that picture is very dark and hard to see. The sound is fine. We have called Best Buy and Philips, but they have not been able to provide a solution. From looking at other posts, I think this might be a panel or small signal board problem. Is this something I can fix myself, or do I need to get it repaired by a professional?

Thanks for any help that you can provide!

Samsung plasma pn50c450b1d no picture no sound


Sounds like 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://electro-medical.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.

My lg plasma tv is cutting off the edges of the shows we are watching. I cant find a setting that will take care of it. Can you help


hmm normally these settings are found in the picture settings of the set top box or just a setting in the tv's picture settings now there might be an option to say fill screen that may work best for some or leave the tv in 16:9 some broadcasts may only be in 4:3 at times this is normal broadcasting and not much can be done unless the setting on the picture option is set to fill screen

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
