Phillips 50" Plasma Repair Parts Needed - Model 50FD9955
I was wondering if you guys could help me...
I have recently inherited a dead 50" Phillips Plasma monitor. This monitor worked fine up until 6 months ago. When I press the power button, the green "on" light appears and I hear a click, but there is no display (there are two 5" fans in the housing, they do not spin up either). The first thing I thought was that the power supply was dead, so I removed the back cover and found the board. On the board, there are three small burned areas where some of the components have shorted out. This monitor is out of warranty, and according to Phillips, is not available for after warranty repair. The Phillips help desk person I spoke with gave me a few phone numbers for local repair shops, but told me that they would not sell me the replacement part I need directly...which means parts + labor. Since the power supply appears to be the only damaged part of the entire display, I'd like to obtain only the part I need and replace it myself. Here is the pertinent info: TV Model: Phillips 50FD9955 50" Plasma Monitor Product Link: http://tinyurl.com/c5a4n Defective Part: PNT-503 Manufactured by Origin Electric Co. LTD (made in Japan) Specs: Input AC 100-240V 50Hz/60Hz 7.1A Output +170V 2.0A, +70V 2.6A, +5V 5.0A, +5V 1.1A, +3.3V 4.0A +7V 0.5A, +14V 1.0A, +6V 0.3A The following marks are at the bottom left of the board: 3S110071 (PNT-503) PKG-1939 I've been scouring the web looking for a source for this board, but so far, my search has been fruitless. It would be a shame to throw this thing away, especially when it may only need one part. Of course, there is a good chance that the damage is more extensive than I can currently tell, but I think it's worth a shot. If anyone can provide any help on sourcing this part (or a compatible replacement), please let me know. As a side note, I have very little experience with board level repairs, so I wouldn't be able to repair it myself...but if you know someone who could, then that would be helpful too. I am including a link to pictures of the board. http://img185.imageshack.us/my.php?image=board7uy.jpg http://img345.imageshack.us/my.php?image=damage14xf.jpg http://img345.imageshack.us/my.php?image=damage22bi.jpg http://img345.imageshack.us/my.php?image=damage30wn.jpg Thanks in advance for your help and for taking the time to read this post.

James The problem may be only the power supply, or there could be a fault elsewhere that burned it up. Your best bet is to take it to a shop that works on this sort of thing, they'll be able to repair the existing power supply at considerably less cost than buying a new one. Plasma sets are so complex there's really not anything anyone here can do to help you fix it on your own. |

Here is the pertinent info: It's hard to tell exactly what those parts are from the pictures. The power supply is probably repairable, but it's not a good do it yourself project. Switching power supplies can be difficult to repair, particularly ones as complex as that. If you miss one thing it will instantly blow all the parts you replaced plus it could cause serious damage to the TV. Since the TV was free, it's well worth putting a few hundred into it.

It is only a switching psu?
With no service information or schematic available and multiple burnt components including several surface mount burnt components and landing pads. FYI it is probably the 7 or 8th one I have seen the psu board look like that. Our field tech was quite busy replacing the power supply on the Philips Plasma in the last year all with catastrophic burnt failures. Seems Philips has another wonderful engineering problem. Philips has paid for a couple that were out of warranty when they failed to the first owner. They had to call with receipt in hand and all information available AFTER an authorized tech performed the evaluation. Good thing though as a third person tried to fix themselves and had the back of the set when the tech arrived, customer service denied as an un-authorized person was inside the set. |
