Re: Dynex TV power supply
I assume your meaning these caps? They confused me a bit. I am ordering off [url]http://www.digikey.ca/[/url]
Can you point me to a replacement for these? I have all the rest of the caps on their way to replace everything.

Re: Dynex TV power supply
24v were all over then faded away, 12v just slowly dropped and the 5v was solid.Leave a comment:

Re: Dynex TV power supply
Ok, I'm going to order all the capacitors I need. Should I also replace transistors?

Re: Dynex TV power supply
I will be replacing all the caps. I'm not sure why I would need an ESR meter if I take the caps out and test them with my multimeter? I do have capacitance testing on my multimeter.
am I missing something?Leave a comment:

Re: Dynex TV power supply
I removed the caps from the board and tested with my multimeter.
I have a few pictures. I can get more tonight if needed.
I will also included the service manual...Last edited by whaase; 04-13-2015, 09:12 AM.Leave a comment:

Re: Dynex TV power supply
I did check most of the caps out of circuit and they seemed to test good. None of them look bulged in anyway (I know that doesn't always mean they are not bad)
I will post pictures shortly
Thanks, WalterLeave a comment:

Dynex TV power supply
I have a TV I'm trying to fix. I do know a bit about electronics, but not a lot
The power supply is making a weird buzzing sort of sound and will eventually shut off until it cools down. The TV works great otherwise.
It sounds like the buzzing is coming from the bridge rectifier. While I was probing around, I did get a bit of a shock from heat sink that the rectifier is on. It meters out ok though which is confusing to me lol
I tested the output voltages and my 24v is all over the place.
I will post a link to a small video of the sound, right click... -
