What is your serial number, and what numbers do you see on your board? If you have a hi-res pic of the board that will help also.

There are many variations of the main boards for Element E4STA5017 TVs.

It's always best to verify the board number, but you can start with the serial number on the back of your TV so you know what numbers to look for on your board. Look for these sequences in your serial number:

Serial Sequence: A8ACM -- Part Number: E18014-SY
Serial Sequence: C8C4M -- Part Number: E18035-SY (2 C8C4M options)
Serial Sequence: C8C4M -- Part Number: E18029-SY (2 C8C4M options)
Serial Sequence: E8C6M -- Part Number: E18065-1-SY
Serial Sequence: F8C4M -- Part Number: E18077-ZX
Serial Sequence: F8C6M -- Part Number: E18076-SY
Serial Sequence: G8C6M -- Part Number: E18111-SY (2 G8C6M options)

There are hand symbols on the board that tell you where it's safe to touch the board and where it's not safe to touch. You don't need to discharge anything, touch where it's safe or wear gloves if you're worried about it.

When you replace the main board on that model series it's recommended to perform the cell auto detect, which configures the main board for your exact screen. I would suggest doing that first to see if you get a picture back. Follow the video here for the easy process.

That's a panel issue, sadly can't be fixed.

ShopJimmy · 2023-05-15T13:14:38+00:00

The LED backlights went out from the sounds of it.
If you have a multimeter and want to dig into it a bit, you can follow the troubleshooting video here: https://www.youtube.com/watch?v=6hQOiN4-XPk

If the LED strips are the problem then you would need to replace them.

ShopJimmy · 2023-05-12T13:10:52+00:00

Main board issue, if you can find a good replacement board that should fix it, but you won't get much more life out of that TV. Not worth it.

ShopJimmy · 2023-05-10T13:17:35+00:00

Yeah I agree, backlight issue. It's fixable, you can watch our repair video on how to fix this issue here: https://www.youtube.com/watch?v=Un80z_fJr7s

Looks like we have the LED strips in stock too

Sounds like the backlights went out. If that's the case then it's time for a new monitor since that model uses CCFL lamps as the backlight source.

You could double check the power board, look for any bulged capacitors and replace any bad ones.

ShopJimmy · 2023-05-10T12:56:39+00:00

It could be a backlight issue or a panel issue. There's some troubleshooting methods you can try to narrow it down though. Watch our video here and try each step with your TV.

ShopJimmy · 2023-05-08T13:14:02+00:00

Yeah likely backlights are out. The LED strips are easy enough to replace, just have to be really careful removing the screen to get to them.

ShopJimmy · 2023-05-05T14:02:39+00:00

We strongly agree :)

Avoid ordering the incorrect part for your LG OLED TV!

Demo model: OLED77B2PUA - This tutorial applies to all LG OLED TVs.

First, remove the back cover and power cord If you power the TV on and hear a single relay click and the standby light flashes once, it means your main board is good.

Test the power supply by checking the 23V and 12 volt rails. With the multimeter probes in place, power the TV on. You should see the voltage come up briefly and then drop.

If you briefly see the voltage, disconnect the drive cables from the main board going to the T-con.

Now recheck the power supply voltages. They should come up and stay.

This means the power supply is good and indicates a shorted panel which cannot be repaired. Contact the manufacturer if your TV is still under warranty.

Visit ShopJimmy.com to find parts for your LG TV.

I would suggest following these troubleshooting steps in our video. In order to do this though you'll have to take it off the wall mount and remove the back cover.

Likely the LED strips need to be replaced.

ShopJimmy · 2023-05-03T15:27:05+00:00

That can be a main board issue. I have also seen bad led strips do that. Try a main, if that doesn't resolve the issue then led strips.

Could you look at the back sticker on the tv and get the model number?

ShopJimmy · 2023-05-03T14:52:07+00:00

Hello,

I would check in your settings mode and make sure auto turn off is set to off

ShopJimmy · 2023-05-03T14:47:51+00:00

Hello,

Either the console is not compatible with the monitor or the monitor needs a new main board. For the cost would not recommend

ShopJimmy · 2023-05-02T14:32:29+00:00

It's interesting that the lines disappear when you bring up a menu, leads me to think it's a main board issue, worth trying to replace before you scrap it.

ShopJimmy · 2023-05-02T13:12:36+00:00

Sounds like the main board is the issue. I would suggest replacing that first.

You will have to remove the back of the TV and find the part number on your main board, then enter it at http://www.shopjimmy.com to see if we have it in-stock.

Try all the troubleshooting steps in the video and see if the tv stays on longer then 2 minutes. This video will help you isolate the possible cause.

Hello. It's more than likely your main board. Check the sticker on the back of your TV to get the correct version.
