Philips TV suddenly switching off with HDMI

by BobMoran35 / January 3, 2018 11:06 AM PST


I bought a second hand Philips flat screen 37" TV 3 weeks ago. It has been keeping turning off suddenly by itself whenever I connect it to my laptop or my XBox One with HDMI.
The screen just switches off as if I suddenly cut off the power.
I noticed that it happens when there are suddenly intense variations in the brightness, in a streaming movie on my laptop or in a video game in my XBox.
I tried with 2 different HDMI cables, I also tried both with HDMI 1 and HDMI 2 outputs of the TV. In vain.
It is really annoying as it happens really often when I watch online movies or when I play video games. How can I fix this problem?

The owner had it for about 2/3 years. He told me that it worked perfectly fine with his sons when they plugged their PS4 to play. He sold many items and have always had good reviews on so I believe in his good faith. I have not other option anyway as it is a second-hand product.

Many thanks in advance!

Thanks! How to install the firmware update on the TV?
by BobMoran35 / January 4, 2018 3:46 AM PST

Thank you very much R. Proffitt for your help.

Yes it is the correct model, I double checked it.
I found the appropriate firmware too.
I will get in touch with Philips anyway to ask em how to install the firmware update on the TV? Can I download it on my laptop and transfer it to the TV set with a USB stick for instance?

Cheers and thanks again!

How to install firmware and why I never tell.
by R. Proffitt Forum moderator / January 4, 2018 7:58 AM PST

Is that there is a possible problem if it's done with the wrong file or method then the TV is bricked.

So all moderators here, so far must defer to the maker. I hope you understand why I don't write how to install firmware here.

I got in touch with Philips Customer Service, I am waiting for their feedback.

Have a nice week-end my friend.
