sony 55xd9305 cycling red/green/blue

[zomi]

I have a 55xd9305, its cycling through the test colours

Red, Green, and Blue and then a screen with a test strip of colours.

it was bought dead
have replaced the dps board and its working again
not sure of the history of the set.

whats causing the cycling of colours ?

Try a firmware update thru usb, hopefully it will update automatically, some will.

Looks like you turn tv on then put stick in usb, might need to use the remote or buttons.

Yes I have fixed that issue
they are really picky about u being the original owner
and have the receipt etc..
so bit hard for second user sets..

Ah, I see, I have to say I'm kind of impressed with sony that they are willing to fix a tv that came out circa 2016 for free, I'm actually in SHOCK lol.

Might want to hang on to the firmware, it's ridiculous how the firmware is there one minute then they take it off the site, never to be seen again.

update

I had another set with a broken screen lying around
so i tried that main board too..
same result

so i swap over the tcon and the cables going from the tcon to the dps board
and the pushfit cable going to the main board

now it works...

Do you have the LCD panel model number?

Re: sony 55xd9305 cycling red/green/blue

Just tried the old board that works too..
so its one of the cables or the tcon...

Re: sony 55xd9305 cycling red/green/blue

thats whats on the back

Re: sony 55xd9305 cycling red/green/blue

The tcon is fine too
i think its just the cabling
one of them must have been damage
the push down to release type connectors tend to mess up the cables
if they are just pulled out like that

going to stop now.
tv is working
