I have a Vizio E420VL and when plugged in the logo is orange and push the power button and logo turns white but that's it. Checked the power board visually and no swollen caps or signs of anything getting hot. On the underside all solder joints look good under lighted magnification. I have checked the connection and seem to have all the correct voltages at the plug. I have read on this forum before posting this about a possible EEProm problem with these main boards so was hoping the experts would chime in and give me their opinion on this or if any further testing is required.

Re: Vizio E420VL problem
Craig,
I wish I could help with an exact solution but I have the same set and same problem.
I bought the programmed eeprom on e-bay and it didn't fix the issue. After I replaced the chip I noticed a chip on the main board getting very hot. It is P13HDMI245-AZLE and as I recall it was near the hdmi connectors. I think I missed it in my haste.
You said that nothing was getting hot - but just double check this chip before you order the eeprom.
Mouser has the hdmi chip in stock but I haven't changed it yet.
It is possible that my set has multiple problems including the hdmi chip and eeprom.
Good luck.

Re: Vizio E420VL problem
that tell me it may not be an EEPROM problem, can you correct a signal to the TV, or do you know the last known input that was being used?
I will try to see if there is any sound by connecting to the HDMI ports using a source like PS3, Direct TV or DVD player
or try the flash light test to the screen to see if any picture it present. like the menu once press the button?Last edited by ecking767; 03-30-2014, 03:24 PM.Comment

Re: Vizio E420VL problem
I guess but not always an image can be seen on the screen using a flash light,depending on the room lighting and picture on the screen. or you could have multiple problems.
one other thing you can do is disconnect the two LCD screen cable and then power up the TV.
If you have voltage on "on/off" and "dim" pins , then your main board isn't the problem dealing with the no back light issueComment

Re: Vizio E420VL problem
carefully disconnect the two flat cable from the main board,then power up the TV, too see if any changes come about.
the "dim" on the power supply connector where you measure the "on/off" voltage.Comment

by Super360Ok so here's the story. I was watching tv one day when all of a sudden I heard a pop from the back of the tv set and rushed to unplug the set. By this time the tv already had smoke coming out the back. It was not storming or inclement weather that day to cause a power surge to the best of my abilities. When I opened the tv up, I found that the three capacitors on the psu (highlighted in red) were all bulging and looked they had exploded. I replaced all of them right away and when I went to start up the tv after the "fix" it started just showing the flashing vizio logo as soon as power...

by rajbotHi all:
I have a Vizio E60-E3 I am trying to troubleshoot a no power problem with. Thanks to the help on this board and elsewhere, I was pretty sure I had narrowed it to a power board problem. The board in question is a 09-60CAP0D0-00. Image attached for reference, but not of my board (tv is put away at the moment). FWIW, no obvious looking issues with the board.
I measured voltage at power in and on the fuse and saw 120V, so power is getting to the board.
On the pins out to the main board, I got no voltage at all on any of the pins. I assumed this... -
by x_orange90_xI just got this tv today and it's getting stuck on the wallpaper. When I first power it on it goes to the V logo, then a black screen for about 15 seconds, then a Chromecast error for just a few seconds, and then finally to a wallpaper. It stays frozen on this wallpaper and does not respond to anything on the remote besides power on/off. Likewise the buttons on the tv do nothing either (besides power). I did the "reset" by holding the volume down and input buttons together for 10 seconds. It showed a message at the top of the screen saying it was Wiping Data and would restart soon. After...

by theone111I have an LG Plasma TV 60PM6700 for the past ~12 years.
In the last ~3-4 months I have been having some issues.- Problem: It started with random picture disappearing (sound still worked).
Frequency: Happened about once a week.
Solution: Had to turn off TV wait a few seconds before turning it on again. - Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.

by MICHAEL_2013Good afternoon, Lords of great wisdom. My problem is the following: I bought a Chinese laptop with GN117_MB_V31-T board. (Aptio Setup Utility 2021) (There is no info for that board). And I want to change the logo of the bios. I have used Aptio_V Afuwin to do the bios Backup, then I change the logo with AMI ChangeLogo Tool v5.0.0.2 and everything seems perfect. But when you restart the new logo appears ok. But it automatically enters the bios, appearing a new option RECOVERY, ROM LAYOUT MISMATCH DETECTED - PARTIAL UPDATE IS NOT ALLOWED. If I give ESC it enters windows without problem but always...06-28-2021, 03:12 PM
