Re: Phillips 42PF7220 Plasma TV
Tom,
I can get a guaranteed working Logic Board for under $20. Is it worth swapping it out?

I cannot think of any obvious checks you can do besides checks for resistance. A logic board may be the best way to go.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Phillips 42PF7220 Plasma TV
Which resistors would I test if I wanted to do that first? I have the service manual for the TV.Comment

Tom,
I got the new Logic board and swapped it out. It definitely is better, however i now have a pink band on the left hand side of the screen. Can you tell me what that would indicate.
Thanks,
Dwight

One of the ribbon cables on the logic board is not properly seated. Remove them and check carefully.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Phillips 42PF7220 Plasma TV
Tom,
The problem seemed to fix itself. The band is gone and the TV is working great. Thanks again for all your help.
You can close another success story thread.

Customer said if he keeps it on for a long time, turns it off, and later back on, it takes 10 minutes to get to proper brightness. Is this just a cap issue? I didn't have time to take it apart I was just there to drop a repaired laptop off

Hello,
I am having Samsung PS51E550 Plasma TV. While the TV was working, a crackling sound heard & video went off with audio still ON. After switching it off & ON, the red LED on TV blinks six times & then off.
Opened TV cover & observed foll
a) Green LED on the small PCB blinks at @5-6sec ON & off for 3-4 secs. Red LED on logic board ON
b)Vs & Va on power supply board raises momentarily to 209v & 58v resp & then drops.
c) Cold test on Y-main board shows all 3 pins of FGPF4536 IGBT short to Grnd.
How to confirm Y -Buffer board... -
Hi,
anyone able to provide the service manual for old plasma Panasonic TX-P42ST50E?
It turns off almost immediately (0~5 seconds after pressing the on/off button) and starts flashing the red diode 6 times.
I disconnected the left-hand side board (SC?, both the ribbon cable and the power cable to it) and also another ribbon going to bottom left board. Then the led signal is 8 flashes. According to service guide to another Panasonic plasma it would mean the left-hand side board is faulty. But I'm not sure it 100% applies to my model.
I checked that board for any obvious faults... -
Hi,
I have this almost brand new Plasma was well stored. I would like to repair it for a friend of mine.
I have noticed that it works for few seconds then switches Off the Power_ On signal. Have disconnected boards and left maion board and power supply and still the same. The power supply with PS_ON and VA signals On stays on so it is not a problem in the power supply.
Any one met this problem in the past?...10-08-2025, 07:34 AM -
This is my first posting, so forgive me everyone in advance if I made mistake(s) in my posting.
I know there have been much about this plama tv already and I have read through most what I could find. However; I still have not come across any service lit/schematics for this tv. I even looked for the 50PS11 which would be basically relevant other than display size. Anyone know to find the documentation would greatly be appreciated.
The set that I have has issues with lower third of screen being dimmer than the above portion. From my past experiences with tube, solid state,...
