Sorry Guys, I had to edit and re-upload this Video due to a
I had to represent and subscribe. I just start my business last year and was starting to get discouraged because it’s not picking up yet but seeing and watching you got me even more motivated. I’m looking forward to checking out the course as well.
Good day Marc. I own a Plasma 3D Samsung 60" PS60F5500 and it worked great since February 2014 - although it did not do very many hours as this room is used mainly for XBOX games when the grand children visit on a weekend maybe twice a month. Unfortunately it has now died, and only double flash the standby light in sets of five times. I disconnected the Y-sustain power cable and the TV then powers up and makes bleep sounds when I toggle its switch up and down, but no display. The Y-Sus board part number is ZB 958B A3 391 5XH - BA3. I tested the Mosfets and found two (marked 30J127 - and below 3:K) that are shorted - Q5002 and Q5003. I removed the cap C5172 to gain access to removing them. The Cap tests ok. Apart from this there are 4 big components on the largest solder patches in a group in the center of the board close to these two mosfets, and it would seem that they might also be shorted, although I did not remove them to test - might need a hotter soldering iron for this. The two buffer boards have no visible burn or dry solder indications that I can see. I will really appreciate your help in getting this resolved, as it would be the end of my really stunning Planet Earth, Life and other nature, documentaries and more titles of my 3D collection. Sincerely appreciate all the way from Pretoria, South Afrika, Dawid Sadie (dawid.sadie@gmail.com).
Hey BigDog8882 I wanted to thank you for your part in me fixing my PN51D550C1CFXZA Samsung 50" after watching you trouble that big screen TV, motivated me to give it a try at fixing ours, I even gave you a shoot out on my channel as soon as I posted it but I have to say thank you for sharing knowledge with me and making it so simple and clear enough for me to replace my Y-Main Sustain Board yeah. Keep Up The Good Work!
I have a feeling this field is coming back strong and here to stay for a while. Just look at rate in which record players are being sold now. In the last three months, I have repaired Marrantz, Onkyo, Techniques, Pioneer, Denon, Yamaha, BSR and so many others that I can't remember. Really reminds me of the seventies when I got into the trade.

Bout to dive into my plasma because of your great job in describing and showing the work of hands on !! I’ll check back in after the job. Mine is only doing backlight on and off several times then goes off, and repeats the same process
Looking good. Keep those great informative videos coming.
Really good and interesting ! And I like your "et voilà" !!!!!!!!!! Merci et bonjour depuis la France
Wow really appreciate the video! I have a similar LG plasma that died in a way that seems exactly like this. I'll pull it apart and take a look out of curiosity not sure if I'll fix it either way it's nice to have such a direct example to follow.
I watched the whole video even when that was not the failure of my plasma, and then right in the last seconds you gave me a good tip and starting point to repair it cause the scenario you described about having backlight but no video is exactly what my plasma does.
Nice detailed repair/replacement video!
