Re: vizio xvt553sv no dc power
Ok, I unplugged the wi fi, bluetooth, and tcon, without any change. So now I'm unsure of what to check next

Re: vizio xvt553sv no dc power
The tv was a friend of mine's, he said it just quit turning on so he bought a new one. The p/n is the same for both the new and the original boards. I don't know which components are what. Starting from the bottom of the tv there is a board to the left of the power board, a board center top and a board on the right side. I don't know what btw means I hope you can walk me through this. I'm leaving for work I will check back this afternoon. ThanksLeave a comment:

I just checked c800a filter cap with a dc voltage of 170 the resistors r922 and r601 have o resistance, but The only voltage I can find on the secondary side of the board is the c 951A ,B, and C capasitors showing 5 volts when turned on and 3 volts when turned offLeave a comment:

vizio xvt553sv no dc power
I have a vizio xvt553sv tv that won't power up. I've taken the back off and I have 120 volts on the ac side. I can't find any dc voltage on the other side. Can someone tell me how to correctly check this. Thank you -

Hi I'm Chris, I have no formal training, I just try to fix whatever breaks. It may be a car, a tv, or a leaky roof ha ha. My method is to study everything I can on a subject, fix my problem and move on to the next one. This forum looks perfect for what I need to fix my flat screen tv. Thank you to everyone for your knowledge and expertise.Leave a comment:
