Sony KDL-55W905A blink code

Re: Sony KDL-55W905A blink code

I was never able to get this one sorted. It has been standing since.
I still want to have this set up and running.

My latest findings is that the new mainboard needs some kind of config to be able to work together with the T-CON.
Through service menu I was able to enter set serial code, but I still cannot "match" the mainboard so it will accept and operate.

Those service menus in Sony sets are quite complex and even still I have the service manual I can't understand what I doing wrong.

According to service manual:

Error of panel ID Off Green Blinking Orange
Blinking
Blinking:0.5sec On / 0.5sec

...indicates a state of Error of panel ID. So what next?
Where are the panel ID stored? T-CON?

Hello, I know this thread is about a year now but have you managed to solve the problem with the green/amber blinking lights? my sony kdl-55w805a is having the same issue.
And pls if you were able to get the manual can you post a link here or PM me?
thank you

For anyone with this issue download the firmware via Sony website. Unzip it to formatted FAT32 usb thumb drive. Insert it into tv. Turn on tv. Wait 30 mins. Don't touch tv. It will automatically restart.

Most trouble usually stems is that people do not unpack or unzip the firmware download prior to transferring it to a usb.

Best thing to do is go down to electronic's store in by any USB Flash drive that has a light on it see can see it function. This way you will know it's operating.

Hi again.
I did not solve this. Tried all I could in terms of firmware update, all USB connectors, try to update through service menu.
If I press 'HOME' button while in service menu I get to the main menu, and I also can read the firmware version. So why should a firmware update be needed ?
I would really like to get this one up and running. Any advice is appreciated!

SUMMARY:

Start TV - front led starts to blink amber / green and never stop

What I do sometimes in cases like these the only solution is to buy another Main Bd.

Have you had an issue where the green/orange flash repeatedly?
'it seems to work too good for the mainboard to be bad' is what I mean. I can watch HDMI sources and menus working. (if start by going into service menu first)
When enter service menu I can do most of the things except for changing serialnumber (one time write only) and also cannot change model number. According to SM it should be possible to change model. Now it says KDL-40W905A but should be KDL-55 , its the same MB for those.
