Re: Common Phillips 47PFL3603D/27 Black screen problem
if the TV is laying down (screen side down) and all of the screws have been removed around the perimeter, and about 3 or 4 from the side and middle. the back should just lift off. you also need to remove the 4 screws for the base/stand.

Re: Common Phillips 47PFL3603D/27 Black screen problem
is the TV still powered on or does it shut off?
i've replaced the power board on mine twice. i'm willing to bet that's also your problem. the inverter caps are bad.
go to ebay and search "PLHL-T722A" and you will see a few available out of Hong Kong. total price ~$70 and should take about a week to receive. only takes about 25min to swap out the board.
here's a link to the board i bought.

2 or 3 different types. i found the issue, bad solder joint elsewhere on the board. just not sure where. if i apply pressure to a component or heat sink the problem goes away.Leave a comment:

Re: Common Phillips 47PFL3603D/27 Black screen problem
I replaced the caps on the inverter side of the board and it worked great for a few weeks. then my picture started to flicker between normal brightness and a darker/dimmer picture. Now the picture is dim and will flicker to the brighter version while watching. Would anyone happen to know if there is another component on the board that should be replaced?Leave a comment:

Re: Need advice on good replacement caps.
sorry, the 50V is incorrect. it's actually 1000uF. that's the one i'm having a hard time finding. it's in a good spot on the board though and dimensions are not that important but i would like to keep the length under 35mm.
WB- ultra low impedance
1000uF / 50V / 16x25mm / 3460 ripple / 0.018 imped.Leave a comment:

Re: Need advice on good replacement caps.
Hi PCBONEZ, sorry for the long delay with this reply. I'm having trouble finding replacement caps with the package size and ripple. I've checked mouser and digikey but can't seem to locate. Here are my part specs... they are all Samwha brand..
RD- wide temp range (-55~105C), General Purpose.
2200uF / 25V / 12.5x25mm / 1235 ripple
WB- ultra low impedance
2200uF / 25V / 16x25mm / 3460 ripple

i'm going to replace the caps on my board with some better caps. that should get me through another 5+ years. by then it's time for a new TV anyway.Leave a comment:

Re: Common Phillips 47PFL3603D/27 Black screen problem
yep, that's the part number and it's definitely the problem. on the upper right side of the board is a bunch of 2200uF caps and they are faulty. the only place i could find the board was on ebay and shipped out of China. Just search for "plhl-t722a".Leave a comment:

Re: Need advice on good replacement caps.
Thanks PCBONEZ, that's them. Is there a better brand I can replace them with? This is a common issue and I would hate to replace junk with more junk. thanks again...Leave a comment:

Re: Common Phillips 47PFL3603D/27 Black screen problem
has anyone found a solution for this problem? I have the exact same issue. I purchased what was supposed to be a "new" board on EBAY (from China) and i still have the issue. My first board burned up and was beyond repair. With the "new" board it works but it loses video after about 5 min then I turn it off and back on after 10 sec and it works fine for hours. I could tell the board wasn't new by the scratches around the screw holes and some other dirt/dust. I'm willing to replace the bad components if somebody...Leave a comment:

Re: Need advice on good replacement caps.
sorry, I can't upload images? files are <500K. I'm using the manage attachments "utility" and it seems stuck on "uploading files, please wait".
the caps are SAMWHA 2200uF 25V. one cap has "RD" next to the manufactures logo and the other has "WB". both are 105 degrees Celsius.Leave a comment:

Need advice on good replacement caps.
Hello,
I have a Philips/LG LCD TV with a bad power supply. It started to give off a burning smell and the video eventually failed after a couple of days. I know the caps on the power supply board are bad and want to replace them with a better brand if someone could help point me in the right direction. any help would be greatly appreciated.
these caps have the same values but are different sizes (same height, different diameters)
TV model: 47pfl3603d/27
board part# plhl-t722a or 2722171 -
