Need a schematic or service manual for a Phillips 47PFL7403d/F7 LCD TV ? Anyone KNOW OF A SITE i CAN GET A FREE DOWNLOAD ? [email protected]

Have a Phillips 47PFL7403/F7. The two Large main capacitors on the power supply board are bulging and hot. TV Symptoms are: TV turns on and plays for several minutes normally. Then the picture disappears but the sound remains. Problem will repeat if turned off then on. Have you heard of this problem before ? I am hoping that replacing the largest main high voltage capacitors 450v 150uf Panasonic Series TS-ED capacitors I think, (in the center of the PS PCB) will correct the issue, I hope its not the inverter board also. All other capacitors look normal. I am a tech and only need any advice you can provide. I have not seen this specific TV problem on a LCD Phillips before. I rarely see Phillips TV's. Not sure if I have one problem or two. Anyone who has had experience with SOLVING this issue please reply. [email protected] . Similar thread but no solution: http://www.badcaps.net/forum/showthr...ht=phillips+tv

SOURCE: TV won't turn on

If that large capacitors is defective, the TV should still power up normally but it might produce a humming noise through the speakers.
I would suggest to check very carefully the capacitors on the secondary side of the circuitry, specially the 1000uF that filter the 5vdc line.
Let me know if you require further assistance.

SOURCE: Turn on TV and picture and sound are great for about 60 seconds. Then the picture disappears but sound remains.

I would start with checking the power supply 12vdc output, make sure it is stable with no ripple. If the power supply checks out fine, I would then suspect the main board.

Phillips tv model 47pfl5603d/f7 power supply board need to purchase one pard number 272217100571

Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.

No video, Power light is on or blinking.
TV is making a clicking noise.
TV takes a while to come on
Screen is very dim or flickers.

Again, You can get a power supply repair kit with the parts, detailed instructions, and support from sites such as www.TvRepairKits.com . Or just click here to see more details on their kit.

Here are pictures of capacitors...Notice that the ones below look bloated. They have failed and will need to be repalced.

Capacitor being replaced! Fairly easy DIY fix.

Just brought home my 47PFL7403D/F7 that was a display model. Sam's gave me a Philips remote but when I push the buttons a light in the lower right corner on the TV blinks but nothing activates any TV...

If SAM gave you the Philips universal remote without programming it for your TV, you should request the remote that come with the TV. Does the remote look like this?
