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... -
Hello, I have a Samsung Plasma TV - Model # PN43D450A2D
This was my parents TV and the initial symptoms were that the display was hard to turn on with the display making various clicking noises until one day it would not turn on anymore.
I took a look and found a couple 1000uF capacitors (i believe on the low voltage size) that had leaked out their electrolyte and did not test well on a tester. I replaced them but still no dice.
When the TV is plugged in, there is no clicking, LED status lights (on PCB boards or the front display) and the power on button... -
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 -
Hi all,
I have an old Samsung ps51d550 that would power on with no picture. I was testing the voltages on the boards based on some advice I'd seen online, I took off 2 of the boards to try test the mosfets, but couldn't really get at them...I left it a while, came back and reinstalled the boards to do some tests and it started smoking. Looks like it was coming from this ribbon cable (see attached picture).
As you can see, im an absolute novice with this kind of thing but I don't like paying for repairs or buying new stuff if I can fix it cheaper.
do you think...
