Hello there. Some time back, I had asked about my damaged laptop screen:
My Dell laptop screen has developed some problems. Earlier, there were vertical lines and some colour smudging but they would go away if I pressed on the left or right side, or the bottom of the screen. Now, the problem persists, so that I have had to put an eraser as packing at the screen bottom, at the center, so that it always in "pressed" position. If I remove the eraser, this is what the screen shows:

The first image is of Foxit Reader without the screen being pressed, the second with the screen being pressed (much better, but not perfect), and the third is of a right-click (again, without pressing).
Is there any way you can diagnose where the problem lies, and whether the entire screen will have to be replaced, or some small repair work can fix the problem?
I went to a local shop; the guy there said the screen replacement will cost Rs. 3500. I asked him the name of the company (of the replacement screen) but I've forgotten what he said. It would have three months warranty. This is my screen:

Model No. B156XW04, made by AU Optronics.
I searched on the net, and found that this screen is available on Amazon, but it costs Rs. 10K. I can replace the screen on my own; it seems simple enough - just remove the screens and then disconnect / reconnect the cable and then put back the screws. But the cost of the original make is too much, and I don't know whether the 3500/- screen will be of the same quality as the current one. There's another site selling it for Rs. 4.5K, but I don't know how reliable that site is:
Buy AU Optronics B156XW04 V.5 Laptop Screen Online In India at Low Prices, Specifications, Features, Reviews, Replacement Laptop Screen
The "Specifications" section says the screen has a 1 year warranty.
What should I do - ask the local shop to replace it for Rs 3.5K (from an unknown company), or get the 4.5K screen from the above site (of which I know nothing)?
Another thing: Newer laptops have an FHD screen (1920*1080), while mine is 1366 x 768. Is it possible to install an FHD screen on my laptop? The above site does have AU Optronics FHD screen for 6K:

My laptop (Dell Inspiron 3537 - i5 4200U - 8 GB RAM - bought in 2015) has Intel HD Graphics 4400 and AMD Radeon HD 8670M dedicated graphics card.
Edit: I did some digging around on my own, and found that to install an FHD screen, the LVDS cable that connects to the screen should be dual channel. I don't know if mine is single or dual channel and I couldn't find an answer anywhere. If others still want to answer the FHD replacement screen question, you can go ahead, but I'm not really keen on buying an FHD screen now, since while installing it, if I find that my LVDS cable doesn't have dual channel, and then, if I can't find an LVDS cable replacement, I would be stuck with a 6K screen.
