Re: Le32a553 Button Board Failure Help ?
I would check the resistance between the terminals of the switches to see if it shows leakage resistance.Never stop learning

Re: Le32a553 Button Board Failure Help ?
I fixed the Tv by replacing the button board for £5 as the buttons were 99p each so not worth it. New board in and all working

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

the board (yes, just the motherboard & daughter board) came to my desk with shorted ITE8585E, after ordered a programmed ITE and placing it on motherboard it turned on immediately, using HDMI i confirm that the boot entering the bios since there is no bootable drive attached. then i turned off by unplugging the DC adapter, while preparing keyboard, mouse & some flashdrive to boot into.
after all plugged (including adapter) the board doesn't "auto turn on" like before, pressing power button with no change. without unplugging anything i'm checking voltages needed... -
I was working on this CNC machine today found no keyboard functioning no control relay powering on
The screen powered on and was giving an operation error but the manual was not very clear about what the error exactly was but with a little bit of troubleshooting and finding out that the control relays not powering on and no keyboard functions we narrowed down to this one switching power supply which of course does not have any indicator LED light they are on the keyboard interface/relay controller board
Found shorted diodes on main controller relays there are 3 of them that... -

Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic... -
Hi There,
This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.
After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.
More Details
TV Model - LG OLED77G1PUA
Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt...
