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

[Davi.p]

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?

show yours Power buttom and others key you have on TV
BTW, dont miss with firmware its wrong... because you have error

[Davi.p]

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..

[Diah]

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

[jason123]

I will get you the picture of the button a bit later as I'm at work now. The Set only has one button (upper right of the Main board) - it's a standard push button, not joystick.
I haven't done anything with the firmware - I simply attempted to do a hard reset.

Davi.p, I haven't done anything with Firmware - The hard reset procedure, as I understand it, is similar - Unplug from AC power, press and hold the power button, Reconnect power, and wait for some color change on the front LED before releasing the power button. I never get any activity on the front LED with everything connected - as you noted, I believe due to the fault (if indeed the TCON is responsible for the green color)

[Diah]

forget about reset, just thinking on way to have access to the area of this low R. or mask the wide line EVSS on this ribbon, or carefully scratch and cut the track after caps. at this attempted you need all LVDS in place and turn it normal..
Note. i didnt done those things , as for me panel issue are rubbish if there short inside the glass.... good luck

[Davi.p]

do not listen to that user, he do not know where he stay of home, i never talked to you about firmware, it's a pairing process, again, if you do it with original tcon it's useless..

who is talking of harming sets i saw he never solve a case and is making you touch delicate circuits without doing the simplest tests..

F°°°K OFF,

OP: beside the one i suggest you early at POST #34, when Panel pull more currents cause of short or leak at Module glass or buffer boards, the SoC on T-CON driver boards will rais and send Signal high to MB in order shutting down PSU, this signal Go via 51 pins LVDS to MB, this why when we disconnect this LVDS the mainboards and PSU remain ON ( Optic on and if you feed it signal via ARC HDMI you will hear sound of the source.)

to be more clear, this SOS signal called ( EROOR DETECTION ON ) will go high if there are error, and remain Low if no error, , i / we have found this points and other threat of OLED. , check it to ground it, but be caution it could make fire inside the glass if the short at raw cells.

Is there a moderator in this board that can stop this old fart to insult me? He is ignorant and disturb others.. thanks..

Just so I'm clear, please, you have an arrow and rectangle. The rectangle is the SOS test point that I can short to ground / mounting screw?
If I understand correctly this could cause a fire because something in the panel is shorted? if something is shorted in the panel that means it's not fixable and at that point I don't really care - Common sense? I'll have a fire extinguisher handy. Just want to make sure the short is on the panel not tCOn or fixable area.

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

if there ignorant person who talk sinless was and forever it seem YOU.. read the threat all and see how we start to test.. not just inter threat in order to distributed it,, you insist to do USB firmware..#21 then i wrote its wrong... then you changed mind that only if he buy and install replacement T-CON #35 you see how ignorant stupid Peron you are

so please please for last time don't distributed my following with users issue ... you are not harming me... but your self and the user... so read and learn new things as other and keep silent.
