Sony XR-55A80J OLED TV 5 blinks - Troubleshooting steps

Actually, the "ERROR DETECTION" pin is in a completely different place, don't burn the T-CON.

So add a jumper (short) the error detection test point to mounting screw? What was the first test point you had a triangle on in post #38 ?

hahaha now Lotas... you are wrong the points are no 12 after the ESD Diode... we have threat on it..
this is original threat photo look with glasses and compare. other wise keep silent as other.

Ok, Shorted the "Error Detection" test point to mounting screw. TCON now has 19.x V and 12.6 V - Panel is not burning and not turning on - fuses on TCON intact -

LVDS 51 pin in place?

If you don't understand the checkpoints, then we'll wait for your experiment!

lotas please don't distributed the threat , he did it and Tv are ON so stop please let me thinking how to bring his screen on

LVDS 51 pin in place?

yes

and the TV seems responsive to button and remote, I can hear the beeps when going to "home" screen .. turns on and off with remote.

Only odd part is the white LED in front, has absolutely no activity (doesn't turn on)

[Diah]

yes

do you have laser temperature measure tools or any....if yes.. try monitor the Temp on T-CON and screen corner .... try to put back the T-CON heat skin on.. and keep this configuration... to start with early talking hard reset. ... after u push the power and plug it in wall. count 16-15-1413-till 10 then release and wait 10-15 minute,,, it could reboot 2 time so eyes on screen if any change and your Optic Port

[Diah]

white LED could be disabled by user from setting early... hard rest will bring it back as sign

ok now you really break the balls, now i see what you do with your useless info, i'll wait your technical defeat.. i prepare for a loud laugh

I do not unfortunately have an infrared temp device. I felt with my hand around the edges of the screen, and nothing is warm even. The main processor on TCON gets hot, but touchable.
I'll attempt the reset again.

there are no experiment at all... all my ways here in this forum or other are KNOW HOW

On different LG T-CONs (OLEDs), the locations of the control points are different. You need to read the labels to find out where they are, and not just take a sample from one T-CON. Here is another example of where ERROR DETECTION is located!

And following this advice (photo), you short-circuited the "EVDD RESET" to ground!

And according to this photo, everything is correct, "E.D." matches.

why you are warm writing and the result as expected.. calm down and learn that all.

Yes, in order to prove something to you, you need to spend a lot of time and still prove nothing, just like with the amputation of the IR sensor output on MICOM.

you are stupid person at OLED ..like others from Italian

I get the impression that you are a complete zero when it comes to TV repairs.

I attempted reset a couple of times. PS cycles few times while I am holding the power button. No activity on the front LED (No white /green / red/ blue)...after I release the power button the main board comes on (screen is lit) then 40 or so seconds later it reboots.. then back to main board on and screen is lit. I can hear the beeps when pressing remote buttons. So responsive just no picture
