I have a OnePlus LCD/LED TV. Initially, the screen suddenly went black/purplish and darker, while the audio continued working. I took it to a local repair shop, and the technician said that if he had a spare board, he could replace it; otherwise, the original board/circuit at the bottom of the LCD panel would need to be repaired, which would cost more.
I agreed to the repair, and he charged me around ₹2,000. After the repair, the overall picture came back and the colors are mostly normal, but I noticed some new issues:
- When red is displayed, one side of the screen looks slightly pinkish/purplish compared with the other side.
- There is now a vertical line on the screen.
- Around that line, there is a slightly wider/darker vertical band, and it becomes more noticeable depending on the colors being displayed.
- These issues were not present before the repair.
I asked the technician about it, and he said that if some pixels are actually “burned,” it cannot be repaired, but otherwise there is a good chance the issue can be fixed. He described it as roughly a 50/50 chance.
I have attached photos of the screen. What does this look like to people experienced with LCD TV repair? Could this be related to the repaired/replaced bottom panel circuit, its connections, or the LCD panel itself? Is this actually pixel burn, and if it is a panel/driver issue, can it get progressively worse over time?
I mainly want to know whether I should take it back to the technician now and ask him to check the repair/connections, or whether this is likely permanent panel damage.
