Vizio TV, Only has standby 5v Power, power voltage does not change when power button is pressed stays at 5v constantly. no LED display on the logo at all.

Re: Vizio VW42L HDTV10A [Only Standby 5v, No Light]
I have to be the first one to ask the stupid question so here it goes. Did you try powering it up with the keypad on the set as well as the remote?The strong-minded rise to the challenge of their goals,the weak-minded BECOME HATERS

Re: Vizio VW42L HDTV10A [Only Standby 5v, No Light]
yes. neither have any effect.Comment

Re: Vizio VW42L HDTV10A [Only Standby 5v, No Light]
after doing some voltage readings, PS_On has no Power whatsoever going to the main board. 3 or so mofests in the middle of the powerboard also have no voltage.Comment

Whenever possible, post clear pictures of your power board. Use "Manage attachments" when posting these pics.The strong-minded rise to the challenge of their goals,the weak-minded BECOME HATERS

Re: Vizio VW42L HDTV10A [Only Standby 5v, No Light]
Looks like a 1W or 2W resistor. But even a 5W resistor would fit there. Just get the wattage higher than the original. (Make sure the replacement is bigger.)
But... what makes you think it has failed?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Vizio VW42L HDTV10A [Only Standby 5v, No Light]
Vizor, How about a picture with a ruler next to the resistor?
Also, a resistor of this value is often used to sense current. This may have failed because something else was shorted.
tom66: The hole in the resistor kind of indicates it might be bad.

Re: Vizio VW42L HDTV10A [Only Standby 5v, No Light]
I've seen resistors with black marks that are fine; but a hole would usually be pretty bad. I did overload a 3W resistor once. The only sign of failure was that it had darkened and the colours on the bands were darkened; however from a casual inspection you wouldn't know the difference (it went from 680 ohms to open in about a minute when 20W dissipation was used.)Please do not PM me with questions!

Re: Vizio VW42L HDTV10A [Only Standby 5v, No Light]
also checked the main board, checked F1 and F2 on a 200 range ohms, F2 has 0.5 and F1 has 0
was looking at this thread. same issue.

Re: Vizio VW42L HDTV10A [Only Standby 5v, No Light]
added a new Fuse to F2 and now the power supply has no power at all.Comment

Re: Vizio VW42L HDTV10A [Only Standby 5v, No Light]
Those resistors do not just burn open for fun. There is a reason why it burned open and there is a reason why the fuse blew. Hopefully, just the fuse blew again. I wouldn't power this thing up again unless I found out what shorted out to take that resistor out, and the fuse.The strong-minded rise to the challenge of their goals,the weak-minded BECOME HATERS

oh, i shorted the resistor out the fuse was blew before that happenedLast edited by Vizor; 11-15-2011, 07:56 PM.Comment

Replaced the Resistor now soon as i hook power up the resistor blows instantly. what could cause this?Attached FilesComment

I have a Vizio E550i-A0 that will not power on. It also does not display the standby light in the corner. I disconnected the main board cable to see if the backlights would light but they did not (maybe this is normal for this set?). I checked the voltages on the plug and they all read in mV or 0, so there's no voltage there. The fuses are ok, and the voltages of the 450v caps read about 160v. I see no visual damage on either the power supply or main board. I have read online that the main board is usually the culprit in this model, but not getting backlights with the main disconnected makes me... -
Have vizio E60u-D3. No standby light. Have searched and read all D??u-D3 posts. posts with same symtoms fixed by new power supply, one guy needed back lights also.
main boards are kinda spendy and, out of stock alot of places. i would like to fix my board.

Hello everyone,
I got a Samsung The Frame 55 inch TV for free from uncle cause it is not turning on anymore. I am in the second year of training as an electrician so I have knowledge already but I am far away from to be a pro.
The TV has Standby but ist not turning on. A Friend of mine owns a 50 inch Frame TV so I checked the One Connect Box and the One Connect Cable there. Both are good and working normally. I have opened the TV case and measured some voltages on the Board.
What I already found is that the 12.8V are not an the connector to the main board connector to the power... -
First off i want to say hello, as i am new and happy to be in the presence of people that know much more than me in these situations. I have searched through quite a few threads and not found and issue just like the one i am having. I just acquired a Vizio D650i-B2 that I was told just quit turning on and has no standby light. Going through some light diag last night i found that the set has a steady standby 5v at the power board connector. without removing any of the boards yet there is no obvious signs of burning, bloating, or cracking on anything that i see. I unplugged the IR board as i saw... -
Hi. I got a Vizio with no power or standby, and won't turn on with remote or button. I checked the voltages on the connector and all read 0.00V or nearly 0(0.050 ON/OFF pin). None of the pins are labeled STB for standby although I do see some 5V pins. Other than the obvious standby led, which isn't coming on, is there a way to check for standby voltage on this PS. I'm trying to see if my problem is the PS or mainboard. Some Vizios I have fixed with no standby led me to think it was the PS but it turned out being the mainboard. Any experience with this set would be greatly appreciated.
