Faulty LED Screen Damaged 2 Laptop Motherboards

[Adept PC Repair]

Just to inform people, just in case they get a similar scenario.

I ordered a screen from LCDS4U (a reputable ebay seller). Upon installation in the Compaq CQ61 it was meant for the screen worked but had no backlight, previously the damaged screen lit up fine.

The laptop then would no longer power at all, upon closer inspection the ENE chip was scorching hot when the supply was plugged in.


I then proceeded to try the screen in a Toshiba Satellite C850 I have in for repair.

The screen previously was damaged but still lit up. Now with this screen connected, no backlight. I proceeded to try the original and again, no backlight.

I had to spend about 2 hours of my time fault finding and finally found a faulty backlight fuse on the toshiba, I replaced this and all is fine again.

However, I am now with a Compaq CQ61 which has a faulty ENE chipset.

I find this the most defective screen I have ever purchased, and will not be buying from LCDS4U again.

First off your post is very confusing. Maybe it's just me.

But my question is, are you really going to stop using a seller because of one bad screen? I'm not a buyer of LCDS4U, but it sounds like you had a bad screen, not like LCDS4U designed the screen and it screwed you over so its there fault.

Out of curiosity, did you remove the battery and ac power before unplugging or plugging in either the new or old screens?

All power sources removed as always during screen replacements.

I won't be purchasing from them again to avoid getting another screen with such a bad fault. Yes, they don't manufacture them, though they are clearly selling them. May have been a minority but I'm not willing to take the chance again.

so if you buy an apple that after you get it has a worm in it (looks good from the outside) you will no longer shop at that walmart?
Or you get a DOA TV then suddenly it's the store's fault for selling it to you --- how do you expect these to be tested? if you are US importer/distributor you aren't going to open EVERY single display and test it on a laptop before sending it out....

Seems a little ridiculous to me to stop buying from a reseller for that...

 

[Adept PC Repair]

Be as it may, it is my choice not to purchase there again.

Whole purpose of the thread wasn't to name and shame the reseller, though I understand it can seem like that.

Main purpose was to describe how the screen actually damaged motherboards rather than just not working and for people to look out for such faults. Rather than trying the screen in other laptops to test, try a different screen in the same laptop.

Its a bit different buying a product and returning it when faulty, but buying a part, the part then damaging a customer's machine is a bit different.

Seems to me this is one of those situations that no one could have forseen. That's the breaks, we as the shop take all the risk in repairing the systems. *%&$ happens. I missed in your post where it damaged two motherboards maybe I just don't read well... wierd so you connected the screen to 2 different boards and they both burnt out? Is that correct?

Hi, yes, the screen was connected to 2 completely different laptops. Damaged the ene chip on the motherboard on the first and the smt backlight fuse on the other.
