    HP envy 23 recline display problem

    hello everybody

    I've got from a friend a "dead" HP envy recline 23 (23-k010ef) with a screen displaying flashing colored lines horizontal and vertical as soon as switched on.

    I've opened the beast and verified cables but didn't found any evidence of failure.

    This touchscreen 23 machine is expensive and deciding to destroy it for good is a painfull decision.

    I've seen that the screen it self is a common 23" hidden behind the touchscreen it self.

    of course, this all in one system does not have an external monitor connector, so no way to test on another monitor.

    My question is : do I have a way to be sure that this failure is due to the screen and not to the GPU? purchasing a new replacement screen can make sense, but only if I can be sure that the failure is not somewhere else.

    disconnecting the internal vga cable just remove anything from the jumping lines. the backlight stays on.

    the screen flicker (only line, not the backlight as far as I see). and I hear a little noise coming from the LED zone (bottom of the screen).

    any recommendation is welcome.

    best regards to all of you

    JM

    Connect it to external monitor see what you got. If it show the same picture, you got BGA problem.
    Try another working screen or screen cable.

      hello

      This was my first try, but there's only a HDMI connector and it's a input, not an output.

      no way to test on an external monitor.

      any idea?

      best

      JM

        That to me looks like a panel failure more than it does a bad GPU.

            by mmccomputer
            I have an HP model : 14-cf0011nf and I want to change its display screen (it has an original 14" full HD TN 30 pins panel) which works without problem but I want to put another screen with an IPS panel, the problem is that I tried several screens but there is no display except with the original screen, I never had this problem before I changed hundreds without problems but this PC is not 'accepted than its original screen
            otherwise on the motherboard it displays edp and I don't know, do the panels I tried only work with the LVDS protocol?

            LCD TV Green/Pink screen problem
            by jimjoe123
            I have a Dick Smith 37" LCD TV, Model GE6804. I am using it as PC extended monitor only.

            Problem is while watching tv, I hear a semi loud click(like a electrical breaker tripping due to overload, just sound like it but no actual electrical overload), then screen is covered with green or pink. I can still see the original picture image but overlayed by green or pink. See attached images. Pink.jpg is what I see, and Normal.jpg is before green or pink screen, What I captured was pink screen, but about 80% of time it's green and 20% of time it's pink.

            Then each time...

            Hi All,


            We've got a HP Envy 12th gen that has been dropped and the LCD panel itself has cracked. The glass is fine just the panel itself is cracked. We ordered a replacement screen assembly using the part number off the HP part surfer website.
            Upon installation the touch screen now does not work either in UEFI or win 11. Device manager under the "intel Precise touch and Stylus) menu notes "This device cannot start (code 10) Status_Device_Power_Failure".

            I've tried all the usual troubleshooting steps like reinstalling the driver, uninstalling...
