Re: Vizio E552VLE Not Turning On
I can't seem to get a reading for those. If I put a paperclip or something metal around the tip of the red lead I could probably get far enough down to get a reading but I'm not sure how dangerous this might be...?

Re: Vizio E552VLE Not Turning On
Is it possible that I'm not checking the voltage in the correct places? The wires were easier to check on Cn201 and 204 but they go farther into the plastic on CN202. Should I be checking where the wires go in or at the base of the plastic housing?

Re: Vizio E552VLE Not Turning On
ok thank for your help. I will wait and see what BudM says regarding this. I did get a little shock from the metal box below CN204 that just scared me when it hit my hand. I can see lights through the back of the screen while its stuck on the "V" screen and I was assuming those were the backlights, but maybe I am mistaken? Like I said the TV comes on and just gets stuck on the startup "V" image which I would imagine requires the backlights?

Re: Vizio E552VLE Not Turning On
OK for the CN201 PS-ON I got 3.20vdc.
CN201 had 12.09 vdc
CN204 had 19.46 vdc
I could not seem to get a reading from CN 202 with the TV turned on or off. I tried it from both sides of the plastic housing where the wires came in and could not get anything from where it said 24V or the A, B, C wires (B looked like it was empty where it was labeled) Could this be significant or was i just taking the readin wrong?The little metal box next to it appeared pretty warm after just a few seconds of being on.

Re: Vizio E552VLE Not Turning On
I have been trying to find info on how to test those things that BudM asked but I guess I am just not looking in the right places online. I've located most of the things he wants to test but not sure what to set my meter on, where the black pole needs to be when touching the red one to the location...etc

Re: Vizio E552VLE Not Turning On
If I bought a new main board online for $150-$200 is it a pretty certain chance that this will fix it? Also, could someone talk me through replacing it. Looks fairly simple but there are a couple of very small connecections on left side that I'm not sure how to remove. Can it all be done without melting anything?

Re: Vizio E552VLE Not Turning On
Yes the backlights work. If I left the TV on it would stay on the startup "V" screen indefinitely. The problem is that only about 1 out of 20 or 30 times does it finish the startup "V" screen and go to the HDMI input so that you can watch TV.

Re: Vizio E552VLE Not Turning On
The heat did not work, but the picture was not the same board so I might have been heating the wrong thing. If I knew for sure that it would work I would buy a new main board. Can someone walk me through how to tests those things that Bud M suggested....

Re: Vizio E552VLE Not Turning On
If I don't have a heat gun can I use the wife's hair dryer? If it works would I need to keep heating it periodically or would doing it the one time fix it for good?

Re: Vizio E552VLE Not Turning On
Looks like those are $150-$200, not sure if I should just get a new one. Are you fairly certain that would fix the problem?

Re: Vizio E552VLE Not Turning On
I do, its an E Tek10709. The TV turns on and gets stuck on the opening screen which is a big white V on the screen. If you turn it on and off enough it eventually goes to the HDMI input and works perfect.

Re: Vizio E552VLE Not Turning On
I apologize but I am very new to this stuff. I have a volt meter but I'm not sure how to use it to test the areas you are asking. The backlights have to be working because when I power on it goes to the V screen and the back of the TV is all lit. Would you mind walking me through how to test those places you asked about?

Vizio E552VLE Not Turning On
Hello Group,
My TV is just over 2 years old and for the last 3-4 months its been hard to get turned on, progressively getting worse. It has the orange colored Vizio emblem on the front when not turned on which is correct. When it is turned on all that shows on the screen is the big V on the start up screen. About 1 out of 10 it will come on correctly after a few seconds of the V screen and work perfectly for however long its on, but its becoming more infrequent. Also, it wont turn off without the power being disconnected. We have begun just unplugging it back and forth until it works properly...
