Usually, the service menu is accessed with the tv OFF, so it might work. With a google search, you should be able to find how to get there with a few button presses. It will likely be the same for many Sonys so don't worry if you can't find one for your exact model.
Is there a way where you can "load" the TV by pressing a combination of buttons to give you a limp mode type of setting? By this, it would be like loading in safemode. I don't have a Bravia so maybe it can't be done.
I fixed the problem! I called a technicial from one of the Sony certified repair shops and he suggested I unplug the TV for at least 15 minutes (I previously tried but for less then a minutes). So did unpluged it, but it was still turning off by itself after few seconds without any image. However, it kind of re-enabled the USB reader and was able to write the correct firmware. Yay!
Hi.I need help asap.I did a software update on my sony bravia KLV-32BX300 with a wrong uodate meant for tv in colombia only.I am in South Africa.How do i fix this ir atleast restore it back to the original version.Also my tv has a red line through the screen and the screen changes colour everytime.How do i fix these problems?
Did you try unplugging it for at least 15 minutes to see if that would allow you to reflash it? Did the problem with the red line and the shifting colours happen after you tried flashing it, or before?
