How to factory reset a KDL-32EX720 Bravia TV? and what are the advantages and disadvantages of resetting it?

SOURCE: No Picture on TV when Power is on

This seet should provide some diagnostic help. The standby light should be blinking a repeated count with a pause. Post that count here. Also, is there sound?

The above info will indicate the problem circuit which will then suggest the remedy.

Thanks,

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

While holding down the UP arrow key, press the power button. The TV will turn off and back on and reset to factory default settings. Hope this helps

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

Probably you are in "shop" mode of TV. Try to reset your TV and go through initial setup. Most important - choose "home" instead of "shop" when asked during initial setup. Resetting - keep up arrow pressed and switch of TV. Keep the button pressed when TV automatically switch back on. This will reset TV to factory defaults.
