News on my Sony A1 OLED tv with an oval patch in the middle of the screen, my A1 is 4 years old and recently it developed a patch in the middle of the screen which was noticeable on a red background, this made flesh tones turn a green colour when faces or anything which requires red passes through the patch on the screen.
this tv had a 5 year Sony warranty, so I contacted Sony support and explained what was happening with this patch on the screen.
This is the procedure I followed from Sony support, firstly I was asked to calibrate the panel by putting the tv in demo mode and powering the tv off and on three times, this did not solve the problem, next I was asked to refresh the panel this still did not help, I then contacted Sony support informing them that after trying all as above the patch had not disappeared.
Sony asked me to send them screen shots with a totally red, blue, green and yellow screen, I was able to achieve this by playing a utube test video and photographing the screen.
I sent this to Sony support and awaited their response, a week later I was informed that I was in a queue and my matter was being looked into, three days later I received a email from Sony saying they would replace my tv with a equivalent specification tv as my model is no longer available, the tv I was offered was a KD65AG8 which is classed as a factory new tv. I excepted their offer which I thought was fair even though the replacement was a much cheaper priced tv, there will be a one year warranty with the replacement which Is ok having in mind that I have a year left on my A1.
I hope this helps anybody that may have a similar problem and if under warranty can have a good outcome.
