How do I diagnose failing screen vs graphics card?

[Neverhavemoney]

Hey everyone,

I've been having an issue lately. I have a cleveo wc870 laptop with a ATI mobility 5870 graphics card on board. For the past few months, I have been dealing with on and off the screen not turning on when the laptop powers on. It will random resume working a few weeks later. In the meantime, I am able to use the HDMI output and connect to my tv so the laptop is functioning properly besides this. I have done many rounds of new thermal paste, but the issue continues to be there intermittently. Does anyone have any suggestions so I can see if I need a new graphics card or if my screen/connector is on it's way out? The laptop is almost 10 years old but she still runs like a beauty besides the graphics issues.

Thanks everyone,
Ben

If HDMI to TV functions without issue, it's your display, probably inverter, short, or circuit breaker. You can usually obtain a new display on Amazon or EBay for aroud $50 US.

Didn't have any luck Googling your particular Clevo model but a plethora of others appear.

If it runs normally using the HDMI and the TV, I would say it's the screen but it also can be the graphics electronics for the screen, it's hard to tell.
On a laptop, normally the graphics GPU isn't on a card but soldered to the main board.
As you had opened to replace the thermal paste, you know more than I do. BTW, thermal paste never needs to be replaced if you don't remove the heat sink.

Agree with Megahertz07, except regarding the thermal paste.

I've replaced thermal paste that has deteriorated, i.e. dried out, cracked and shrunk to the point that the processor is overheating, albeit, on old machines with many use hours. I don't believe your issue has anything to do with the paste.

I'm guessing you mean Clevo W870cu. If you search for Clevo W870cu Screen on amazon or ebay you get several hits. If I was in your shoes I would buy one, try it, return it if the symptoms don't improve. It does sound like a screen hardware issue.

You need to read the return policy on electronic components. The overwhelming majority of electronic components are not returnable/refundable ever to anywhere.

The only issue I have with this statement is that it is wildly untrue. But other than that, you make an excellent point, one should always check the return policy. For instance if he does the search I suggested the first two hits, amazon and ebay, go to links with free returns for 30-days, buyer pays return shipping only.

Regarding the Clevo screen, I was referring to video on how to replace the screen not availability.

You're most welcome. Hope the new screen works for you. Purchase a new one, not used. Used may have short working life left; you never know.

If that isn't the problem, and the seller won't accept returned opened electronics components, you could offer it on eBay or Amazon as new opened unused.

So I'm having trouble locating a reasonably priced screen for this computer. I opened her up today and took a pic of the tag to match with others but no luck. I have always been good with software but hardware is tough for me as a novice. Any help locating a reliably sourced screen would be greatly appreciated.

Thanks,
Ben
