Alessandro,

What you have here is the safety circuit being enabled to protect the TV. This happens on these sets when one of the following occurs:-

One of the power supply voltages is missing, over voltage or overloaded.
A bus error has occurred with data between the various IC's
There is an error in the EEPROM

A B&O engineer can put the TV into service mode by using a jumper and it will show him the error which has occured. With this information an assessment can be made of the likely fault and therefore cost to fix it.

I would have it fixed if it was previously working perfectly.

Hi,

I wonder if you can help me in detecting the problem in my TV.

Synptoms:

During the last 2 - 3 days, the TV began to display only in B&W
After that, it switched off, but if I tried to switch it on again, it stayed on for about 1 minute and then off again.
Today, it does not switch on anymore, if I try to push TV on my remote control, I see the red led to go off and on again, but nothing happens.

I would like to know the nature of this breakdown in order to understand if it is convenient to repair the TV or not.

It's a fantastic TV, I love it but I want to have your opinion before putting my hands into it.

Thank you

Alessandro
