Sony KD-49X9000G black screen
« on: December 28, 2024, 04:28:27 am »
Hi everyone,

First, Merry Christmas!

I purchased a Sony KD-49X9000G almost 5 years ago and I only use it with my laptop plugged in via HDMI. Last night, the connection between the 2 devices went on/off for some time as if the hdmi cable wasn’t working properly so I changed it with a new one but it kept doing it. I then turned off the tv.

This morning, black screen, no leds… nothing can be done. I checked the fuse, tried other power sockets, tried all the possible resets I found online (60s push etc…) nothing.

The power chord is fixed so I can’t check if that’s the issue unless operating on the tv.

Based on all my research, it seems to be a power issue and I’m happy to try and DYI the thing (nothing to lose anyway…) throwing a 5 years old tv makes no sense to me, for principle’s sake. I now wish I still had my old Pana plasma which doesn’t seem to give in after 20 years.

Thank you so much for your help if you have any guidance on my problem, have a great day all!

François

Sounds plausible that there is some issue with the power supply.
Crack it open and power on your multimeter.
When it fits stop using the hammer
