Thin black horizontal lines across TV: Sony KDL 42W706B.
I need help with my Sony KDL 42W706B television. This morning the TV was working perfectly fine and at some point think horizontal lines appeared starting from the bottom left and going half way up the screen. In certain conditions it’s hard to spot but in others it’s very noticeable. Been doing some research and it’s not clear what the issue might be. Tried to take some pictures to highlight the issue but they are a little difficult to spot the fault. I did attempt to see if I could take off the back panel and see if anything was amiss but it wouldn’t budge once I removed all screws and I didn’t want to force it off doing damage to anything.
Added two pictures of the back panel like I was asked. Though according to what I’ve read there doesn’t seem to be any point in trying to fix this if I could get into it anyway. Frustratingly I can’t afford a new or used TV to replace it right now.
If anyone as any knowledge on what I might be able to do or if I’m screwed at this point I’d appreciate the help as I’m finding it hard to get solid information.
Appreciate the help.
UPDATE: The screen as gone black entirely now. Still starts up with the backlight working but there is nothing displayed on the screen and I tried the flashlight test but couldn’t see anything. Please help!

Macho Fantastico did you replace all the screws again when you took the picture? I believe this is a model where you have to remove the stand as well
I found a way to remove the back panel. Basically it needed more force to remove from it's clips and I've had it off checking over everything. Disconnected/reconnected cables including the ribbon cable going into the main board but the issue still remains. The more research I do the more I suspect it's possibly to do with the the side connections (failed Gate Drivers I think they might be called) but I'm not sure how to gain access to them easily. I've looked for guides etc but had no luck so far. Seen videos of people with similar issues who've put slight pressure on those connections which fixes some issues and considering I don't have many options I thought it was worth a try. I've been asking about but you're the only one whose really provided any real advice, it's much appreciate especially considering I can't really afford a new TV at the moment.
As for the stands, no you can take the back panel off without removing the stand. Thanks again.
