Re: Phillips 32PFL3403D-27 power board issues

Definitely. The picture of the location of the bad capacitor is above, but I will attach it again below here. It is the C932 location on the schematic. The top was quite bulged out on the old capacitor. The suspected loose connections were on the board shown in the second picture below with red circles around them. I also took off the switches and worked everything, so I'm not 100 % sure that a sticking switch wasn't involved as well. I should have checked the tv between steps to see which actually fixed it, but I didn't do that. I will...

budm...thanks for the pointer about having to have the other cards connected. I would have wasted a lot of time on that. I did find the issue and the tv works great now. It was a combination of the bad capacitor and a bad connection. As I wiggled components I found one that made it work properly when I wiggled it. Again, thanks for the help!

Re: Phillips 32PFL3403D-27 power board issues

Wow, I had overlooked that completely. So update to the problem. I plugged the power board back in and hooked everything up and now the tv will come on. It powers up and the screen comes on like normal, but if I change the volume or channel it powers off briefly and then powers back on...any ideas of where to go or look from here?

I am currently working on a Phillips tv (32PFL3403D-27) that had stopped working a while back. First it started shutting off from time to time or even turning itself on from time to time. Eventually, it wouldn't even turn on other than the power light being on. I pulled the power board (picture below) out and with it powered on I am getting no voltage (24 V or 12 V) at the outputs for the scalar or panel. I am getting the 5 V output, but that is it.

Tracing the schematic (attached below), I saw that the voltage for those pins comes off of the secondary of the larger transformer...

Hello everyone!

My name is Micah...a little about myself...I separated from the Navy and am currently a part time airplane mechanic down in Florida while finishing up my bachelor's in electrical engineering full time. I'm finishing up my junior year and getting into the brutal upper division courses. I like to tinker and while the books help with some of the theory, there is nothing like hands on playing around with stuff to really make it stick. I am currently working on a Phillips tv that is really stumping me...
