Since its just artifacts/pixels its definitely nowt a power supply or inverter fault, I would take it apart (usually you take off the front fascia off, its always press fit) and just have a general look around and reseat all the ribbon cables and look for blown/domed capacitors, those are cheap and easy to replace.
If you lived close I would happily have a look for free but we have covid and i live in Wales haha.
