i need some opinions about this. I purchased a main board from ebay and installed it. the tv came on and was working good. then i decided to connect an antennae to the 75 ohm input. the input is there but broken and will turn around and around. of course there tv is not getting any signal. while checking the 75 ohm input i noticed that the tuner itself was pretty hot to the touch. my question is would there be a good chance that the tuner being hot would eventually kill the tv? if the customer does not use the antennae input as lots of people do not, i will just instruct them to use the other inputs, HDMI, ect.

Re: vizio E470VL tuner hot to touch
I would return it and get one that is fully functional. If something is shorted and drawing too much current, it is quite possible that a component further up the chain could eventually fail. The other option is to just remove the tuner from the board. -
Re: vizio E470VL tuner hot to touch
the problem is i have been looking for this particular board for over a month now and I finally located this one and it is the only one available. so I will follow your suggestion and remove the tuner from the board. thanks johnboy1313Comment

Re: vizio E470VL tuner hot to touch
Are you sure removing the tuner does not generate fault codes since the main processor does not get a response from the tuner via I2CComment

Re: vizio E470VL tuner hot to touch
I was thinking the same thing. so I did not remove it. after checking again it was not as hot as i first thought. it is just really warm, not hot. and it is in close proximity to the large processor heatsink that is even warmer. so at this point i am letting it run overnight and i will see how it is doing in the morning.Comment

I am trying to convert a HP EliteBook 840 G7 notebook from a non-touch to a touchscreen. I purchased a complete touch LCD assembly with a screen/back cover/bezel/video cable and swapped it out with the original non-touch LCD assembly.
The screen works but the touch does not. I know the new LCD assembly is completely functional because we tried it on a similar touchscreen EliteBook 840 G7 and the touch works there.
I contacted the seller and he said screen conversion like this will not work due some difference in the motherboard for non-touch and touch capable EliteBook 840 G7.

Hello,
I have a question that's driving me a bit nuts recently.
Is the touch board on Surface Pro 4/5 somehow married to the motherboard? I have a few Surfaces that, after the touch board change, lost all touch functionality.
- I tried flashing the bios (simple ME clean from a known good bios, previous bios didn't have an intergrated hub enabled), reinstalling firmware, reinstalling windows and even new touch boards.
- In one instance, after I tried to troubleshoot by using a known good screen + touch pcb combo on a Surface that lost touch, the touch board... -
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.

EDITED: I thought my Vizio E470VL has +5VSB and no 12v on the PS board, but after plugging the cable back in and testing the pins on the Main board I realized that I do have 12V. I assume the 12V is turned on when the ON/OFF switch is pressed. The Vizio light in front does go from Standby Orange to White when ON. But, I still have no picture or sound. Test values of PS board are below.
+5VSB= +5.09
12V= +12.18
PS_ON= +2.25
I_ON/OFF= +3.27
LAMP= +3.18
DIM= +2.97
Any more testing I can do on Main board or is it just a replacement?... -
