Hi everyone,
I recently had trouble with a Dell monitor, and you guys really went above and beyond to help me, and I was able to fix it! Thank you!
My TV broke a couple weeks ago, and I want to get it fixed for my wife.
Model: Samsung PN51D550C1FXZA (I often find it online as just PN51D550 or split as PN51D550 C1FXZA).
Specs: 51" 1080p Plasma 3D TV
Symptoms: After plugging it in, it turns on then off then on then off, 4-5 times total, and then the power light does 5 double-blinks. No picture on the display.
Troubleshooting so far:
- I found another thread about this TV, but the picture links are broken.
- I bought a replacement power supply board (model BN44-00444A) from TV Parts Today. I swapped out the board, but the symptoms did not change. It cost about $40-45 shipped. The last picture below is the old board I took out of the TV. Pic 3 is the new board.
- I am a novice to microelectronics, but I do have a multimeter, a hot air soldering station, and a LED blacklight tester (although I've never used it yet). I fix phones and laptops, and this is my first time trying to fix a TV, although I've repaired 3-4 monitors before.
Would anyone please be willing to help me? I will do my best to follow instructions if anyone can walk me through what to do or what to check.
