Question about Philips 50PF9630A 50 in. Plasma Television

1 Answer

I have a Philips 50PF9630A/37 plasma. No picture or sound.

I have a Philips 50PF9630A/37 plasma. The front led turns green and clicks twice like it is going to power up, but does not. It flashes red 6 times slow, followed by 3 fast red, then repeats this sequence until it self powers off. It has a high pitched noise coming from the back until I unplug it. I replaced 2 blown capacitors, replaced the power cord, tried the blow dryer on the capacitors suggestion. Nothing helps.

Quick test of the plasma screen itself:

1) Turn on the TV
2) Try to bring up an on screen setup menu using the remote or buttons on the tv.
3) Does the menu appear? If so, the screen itself is ok.

If it doesn't come up you make have an issue with the screen itself. I am not sure it would be possible to set contrast and brightness settings such that the picture would completely disappear, but I suspect you should be seeing something on the screen just from having turned it on.

We also need to know more about what you have connected to the television. HD televisions typically have several inputs on them including HDMI, digital cable, VGA and component. Let's say for example you have PS3 connected via HDMI. You can tell the PS3 to send audio across the HDMI cable as well as video. You also have the option of running separate connections for your audio signal. It is the existence of these options that make it necessary to understand where and how you have things connected, very specifically.

I have a Philips Plasma tv 42pf5321d/37 with sound but no picture


Thats the great sound of Exploding capacitors on either the power supply board. or another one in there. Now the set is in fault protection. It tried to warn you with the RED blinking LED that there was something amiss by shutting itself down. When you unplugged you reset the error and allowed it to do it again.

Unfortunately the 'green line' issue mentioned in the review appears to still be happening on screens that are shipping to end users. (It's been documented in detail on AVForums).

Hopefully this should be rectified by a firmware change (simply being able to adjust the picture vertically as well as horizontally would help).

The clearlcd technology is new for philips

VERY VERY COMMON IN PHILIPS!!! People all over the internet are noticing the same problem. Philips is still working on it. I will let you know as soon as they have a solution.

Firmware is avialable for download on the philips web site. The latest one that is the bundle of mutiple patches may not patch all the problems. Looks like it has to be applied indivdually.. -anil
