    LG 42PQ200 Plasma has image traces only in some places on the screen

    Producer -LG
    Model No / 42PQ2000
    Chassis / PD92A
    Main board / EAX57566204
    Y-SYS Board -42G2A-YSUS
    Z-SYS Board -42G2A_Z
    Plasma Display / Panel -PDP42G2 ####
    Hello all electronics lovers, this is my first post.
    I have a problem with one LG Plasma, which is the following:
    The LG 42PQ200 Plasma has image traces only in some places on the screen
    Fault description and description of actions taken and measurements on the appliance -
    The mistake is, as I said in the introduction (there are traces of the image only in some places), if I was able to describe it well in words, and here is a picture attached.
    Volts Vs, Va, 5V, ok, and voltage 15v is 16,8V but I guess it's within tolerance limits
    Nothing is blown to either the Y or the Z board, there are tons of responding to remote controls but pictures only in some places (if those bright scattered pieces on a black background can be called a picture)
    Where to look for a bug?
    Thank you

    Post a picture of the white label on the plasma panel, the entire back of the TV, and one of the ZSUS board. This is almost certainly a ZSUS problem.

      Sorry, I didn't say I already tried the correct z-sus board.
      The same goes for the other z-plate.
      It's the only plate I could get to try.
      Is it possible that the problem is in the control board or the plasma panel itself?

        Highly doubtful in my opinion that it's anything other than a ZSUS problem. You can wait for others to chime in but from my experience with similar models, that's my best guess.

            Toshiba plasma 50WP16 wierd double image fault
            by piershs
            My 2001 Toshiba 50WP16 50" plasma TV has, after 20 years of trouble-free service, developed a wierd fault in the last 14 days during normal viewing - with no loud bang or smoke or any other excitement.

            Every 15-30 secs the right hand half of the image has a "glitch" for about 1 second before reverting to normal. The glitch has two forms and also depends on the aspect ratio setting (see photos):
            • 16:9 either a) a visible seam between LHS and RHS of impage or b) LHS image duplicated on RHS (photos 16x9)
            • 4x3 either a) no image on RHS or b) RHS image offset by 1/6th
            ...

            TV LG 50PA4500 Plasma : bad image noisy
            by Delired73
            Hello everyone,

            I have an issue and didn't find any solution by myself or on every forum about my LG plasma TV 50PA4500.

            Originaly the TV stopped to work and didn't want to turn ON again.

            After visual inspection, few transistors were broken, I tried to change them but some burned again, so I ordered on full new board. So, I changed the Yboard which was burned by a new one

            It now turns ON and the image and sound are present. But the image is very noisy and only visible when the room is in the dark.

            I check Vs and Va voltages...
