I gave up dismantling it, it's very likely I'd damage the panel now.

So I looked for images of the backsite and found some:

How do you think you can test the whole tv if you have broken the screen?

Re: Panasonic LCD TV: TX-L42ETW5 won't display anything

what? the screen was never broken.

as I said, TV was unused a few months and it just didn't want to start.

btw, baking the a board didn't help.

What temperature did you bake the board at?

@diif

200-215°C for 5-10min.

That's pretty close, you might need to get it to 222 for a bit.

200-215°C for 5-10min.

Lead free solder melts at 217°C. Ideally you want to add some flux around the processor to help with the reflowing.
