I recently upgraded my old laptop with a new processor, replaced the RAM, and even installed an SSD. At first, everything was running smoothly. However, about 30 minutes into using it, the screen's backlight shut off completely. I can still make out the display with a flashlight, which makes me think it might be an overheating issue due to poor thermal paste quality I used on the CPU. I'm not sure if something else could be wrong, like the LCD cable or backlight itself. Can anyone suggest how I might fix this myself? If it's too complicated, I'd also appreciate recommendations for repair shops in Delhi, India.

It sounds like the backlight might be failing, but it's unlikely caused directly by the overheating after just 30 minutes. Often, when laptops are older, issues like this pop up—most likely it’s a damaged LCD cable that got pinched during reassembly. If you’re up for it, figuring out whether it’s the cable or the screen is key, but both can be relatively cheap to replace. I’ve found good components from tech recyclers online, so check for local ones that might have what you need!
Wow, you replaced the CPU? That's pretty impressive for a laptop! Generally, models before the 5th gen Intel still had removable CPUs. Just be cautious—these upgrades can lead to other unexpected problems like the one you’re dealing with. If it’s not a simple cable issue, you might need to look at getting a new screen if it’s the backlight itself that's at fault.
