Re: vizio e600b3 power supply
I decided to use my Energy Verifying Raygun (EVR) and now Everything works! The esr meter was worthless.
Well, I do know it was the power not the main board because I was mixing up 2 power boards - and one them works. And, The tv turned on and the voltages were okay.
I want to thank nomoresonys and budm for Taking the time to help me. Hope next time to have a more challenging project.

Re: vizio e600b3 power supply
Can I measure this with a multimeter while the cap is on the board? I thought I need an evr?...Leave a comment:

Re: vizio e600b3 power supply
my ps-on pin3, doesn't change voltage, everything else you said checks out. What is really odd is on the cn301 lead ,pin 8 (isns) is giving me some odd readings: it is all over the place; plugged in - off or power on - between a high of .54v to a low of almost 0v. also it reads almost like there is a charge and disharge in the range. usually it hangs around.22v-.32v. I will type out all the pin voltage reads in the morning. thanks for your helpLeave a comment:

vizio e600b3 power supply
Hello,
This is my 1st time at fixing LED TVs.
Problem: 5 year old vizio e600b3 suddenly stopped working.
Issue: After pulling back off the and viewing many, many, videos I replaced my 30+ year old analog ohm-meter and bought a uni-t 61E digital multimeter. I diagnosed the issue as a problem with the Power Board as there was 0 voltage on the 4 - 27 volt pins. I ordered a new PCB from online supplier.
New Issue: I installed the 'new' power board and I still have 0 voltage on the 4 - 27 volt pins !! I removed the cables connecting the power... -
Re: New Members - please post your introductions here
hey, thee8ball here. I have been around this game for a long time but I am here looking for help fixing my led tv. I actually bought a replacement at costco but I'm determined to fix my broken vizio e600-b3. I have determined that it may me the power board as the 4 - 27 volt pins on the pcb are all 0 volts. I installed I 'new' power boards from tvpartsguy.com, installed it and I still get 0 volts on the same 27 volt pins - even with the 2 cables detached which lead to the main board....Leave a comment:
