Re: Sony KDL-40WE663 Screen problem

Hi Sorry did not realise you wanted pics, I will again do a factory reset and take some pics for you.
Is there an option to do a factory reset through this service menu ??
The factory reset that I have done, I did through the normal tv settings menu

Re: Sony KDL-40WE663 Screen problem

it may listed reset option at service menu under different name such as "factory default".. also you have option of self check. this will diagnose whole hard ware and if there are error for example at T-CON will be listed too. self check are very useful option at SONY.

Hi Diah, firstly thanks for the help on this tv
Have done a reset through this service menu same result on right hand side of picture
Here are the pics of the service menu, one thing I had a quick look at was the panel selection, it lists about 12 different panels, maybe that may need changing if this board is for a different panel as to what is fitted in this tv

take looks on yours TV chassis there should be barcode or label show the panel No.
in case you couldn't find label. you can pattern the listed Option at Panel Selection. Choice one and test..

UPDATE
Ok a revisit on this tv, I have just sourced a mainboard after many many months of searching for this tv exact same numbers as faulty board
Fitted the board and tv picture is still showing same fault as previous boards ie hazy patch and pattern on right hand side of screen as in my previous posts
I have updated software and factory reset still same pattern and haze on screen
Any ideas please

You might try Budm suggestion. Firmware can't fix everything. Seems to be a thermal problem.
