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

[Davi.p]

Hi jason, do not judge by the test of replacement tcon, it is made incorrectly, in Sony world a new tcon must be paired with the main board otherwise 5 blinks, the same as a faulty screen/tcon, this is the procedure as i took note in my experiments with a lcd set (this can work or not, i found them by casual tests):

Sony tv, prodedura aggiornamento forzato per abbinamento main board - tcon, secondo delle prove fatte, da verificare, forse funziona solo con tv non Android:
mettere il file di aggiornamento su una chiavetta con led, rinominare il file con "upgrade_loader.pkg", inserirla nel tv, tenere premuto il tasto On sul tv, inserire la spina, quando si accende il led blu lasciare il tasto e ripremerlo (non ricordo se breve o lungo), dovrebbe pulsare il led bianco, aspettare che il led della chiavetta smette di pulsare dopo poco, rimuovere la spina, aspettare 10sec e rimetterla, il led bianco fa 3-pausa-7 impulsi, ora accendere normalmente il tv con tasto on sul tv o sul telecomando, se funziona compare normale immagine.

sorry, it is in my main language, if you have problems i translate them..

PS: a guy i helped done this succesfully on an android lcd set..

PPS: so get again a repl. tcon, pay attention to ask the seller that the board comes from a new set or old set cracked screen.... mandatory..

Unfortunately, all these 4 caps are good. High impedance when removed and board still has low impedance.

you need to cut the black plastic inorder to explorer the rest of this EVSS part on this side.. about OLED Module Tester will work on yours set.. i think any repair shop should have one under his hand.. its cheap, however it can be SIY to make one

also you can try the hard reset i explained before after you disconnect only the lower LVDS., so yours set will remain on
Align T-CON will generate white green LED blinking ..

Thank you Davi.p - I will give it a shot. After performing #10, the TV now doesn't have a white front LED. Either the LED died (unlikely) or this TV doesn't have "Blue / Green" mode?
Also, on the instruction, the translation say rename the File. Does the Folder have to renamed to, or just the file?
Thanks

Alight T-CON will generate green LED blinking ..

Seems the material is aluminum not plastic on this model ?
Unfortunately, no TV repair shops in my area within 50 mile radius at the end of the day, the "Jig" will force a signal to be sent to panel. so if I don't get a signal, I'm still unsure if it's OLED panel or TCON issue? TCON is only $40-$50 and I can buy one and try it out?
As I noted in the previous comment, I was not able to get "Blinking Green" on any other color on the front LED - now I only get 5 red blinks after doing test in #10.

the fault are clear at Panel... you have same Caps position at other side and you did compare them.. the hard reset i suggested just to clear error at MB and T-CON
unplug the lower LVDS only turn on the Optik will lit red and remain on.... plug the set from wall, do the pressing on Power then plug in wall remove until white change green... give time

Jason, test in #10 has nothing to do with my procedure, no cables have to be disconnected..

So yes, disconnecting the lower 51 LVDS cable, brings up the main board and it remains on (Optic Light is red)

on Post # 8, the instructions for hard reset, requires the front light to turn green and so on. The front LED now never turns white and doesn't change to green. I pressed the power button for a very long time, over 1 minute, and no activity on the front light.

The procedure you kindly provided, requires the interaction with the front light to turn solid blue and so on, the front LEDs after performing #10 (I don't know why) never turns white or green or blue again. I tried your instructions and as long as I'm pressing the power button (with all cables connected) there is no change on the front LED.

Also, on the instruction, the translation say rename the File. Does the Folder have to renamed to, or just the file?

The file only have to be renamed, i do not know WHY you do the procedure now that you have probably a faulty tcon, it has to be done with a good card.. the procedure is so, tell me if you already understood , put in the usb key, remove power cord from mains supply, keep pressed the power key on the local set keyboard , not remo commander, then plug in power cord, if power led goes blue (or maybe there's another color here, red?) , release the key and press it again (short , long i don't know) if led blinks white wait until it stops, remove power cord , wait 10 sec, reinsert power , white led does 3- pause - 7 pulses, now turn on tv.. hope the image wil come out..

The file only have to be renamed, i do not know WHY .

could you stop harming the users set... this is not the first time... he have error / SOS 5 blinking because of Panel... what you are talking on when the set changed T-CON and the front will blinking white green.. this is not the case...

i am leaving this threat. play as you like
