How to do a complete factory reset of a Sony Bravia kdl-40ex725

Just talked with Sony Support today.

It seems that Sony in Denmark had sent out new software updates (over DVB-T) but also some wrong TV's got updated as well. This caused my DVB-T tuner to not function anymore so I wanted to try a factory reset and it fixed my problem.

So I was instructed on how to do this. I have a Sony Bravia KDL-32P3000 (which should be similar to the U3000 and S3000 as well).

This is how to do a factory reset of your Sony Bravia KDL-32 P/U/S-3000 TV.

PLEASE BE VERY CAREFUL WITH THE SERVICE MENU, YOU CAN EASILY CAUSE YOUR TV TO MAL-FUNCTION!!!! IF YOU FOLLOW THIS GUIDE IT IS AT YOUR OWN RISK!!!

Set your TV in standy (use the green power butten on your remote), RED standby LED is ON on your TV.

Now press these buttons in this order on your remote (pointing to the TV).
i+
5
VOL UP (+)
GREEN POWER button

NOW BE CAREFUL! Dont press any keys just for the fun of it!!! IT MAY DESTROY YOUR TV.
You should now be in the service menu. It will show up as some green letter/numbers spread over the screen (mine are a bit hard to see/a bit faded). In the upper right corner you should have 2 letters TT (two t's).

Now carefully press key 0 and then key 8 on your remote (they should be shown on the screen after the two TT).

Now wait a little while (more than 10 seconds) and your TV should reset with factory settings, just as if you had just brought it home from the TV store.

Best wishes,
Mads

This can indicate a problem with the high voltage circuits. Since this is a new set, it should still be under warranty. DO NOT open up the unit as that will void the warranty. Return the set or request warranty service. Note the 8 blinks when you request service as that should allow them to bring the correct replacement parts.

Keep us posted.

Hello,

Unfortunately, this is a failure of the balancer board for the backlight. The unfortunate part is that the balancer is not available by itself anymore, and the whole panel must be replaced, as Sony only has the balancers attached to new panels. You can contact Sony directly to ask for assistance, and it usually helps.

Hope this helps you...

That symptom may cause by the main board or t-con board, I suggest you do software up grade first.
