I have a 50" Philips Plasma TV which has recently developed horizontal stripes across most of the screen.
TV is a 50PF9630A/37.
The TV is 3 years old and until now has performed flawlessly.
I expect there may be a board that needs replacing (?) as I'm not sure if I'd just be able to identify/replace a single component...
Any help is appreciated, thanks!

I have the exact same problem with my 50 in Samsung Plasma. I replaced the "Main Board" with no success. My next step is the logic board. In the service manual it says that a certain LED on the logic board is supposed to blink. On my logic board the LED is on steady. |

Found Kai's posting while seeking info on an almost identical issue which arose on my 42" Philips plasma tonight - also 3 years old.
Almost faultless in that time - it has had a habit of the screen just going blank for about 10s then recovering from time to time.
Any luck at fixing this, or is it time for a trip to the dump???? |

Hi minnie,
Thanks for the time invested.
I'll take it off the wall this weekend (sigh) and have a look.
If it is possible for me to remove the driver board, for example, do you think it's worth replacing?
I understand it's just a guess, but the boards are certainly a lot less expensive than a new TV.
BTW - I can find the following boards which might apply:
Driver Board
Logic Main
and Buffers Board, plus E, F and G Buffers (although you ruled these out due to the stripes not being vertical).
Best guess? |

Normally, the panel comes with ALL the boards attached. You keep the plastic housing that's about it. Any sustain/buffer board, logic, digital main, power supply comes with the pdp/panel. Not cost effective. Plasma is a big time guess. |

x sustain, y sustain, or y sustain, z sustain. The panel is just that, the panel. |

There's one more clue which might help.
Upon turning on the TV, I hear a relay(?) clicking on.
On turning off the TV, I used to hear a clicking.
This clicking at "off" no longer occurs.
Now for the question -
I've checked ebay for this TV's model # and found the following:
They do have a "Logic Main," but I don't see anything labeled x/y or sustain panel. Would this be called something else? |
