I left it for diagnostics, and the power supply was sentenced.The spare part for Ali is three times cheaper, I changed it myself.It also turned out to be a problem with color rendering, although there was no such problem before the diagnosis.Disgusting service
I applied to another workshop, the lamp in the Panasonic projector was replaced, but it still did not turn on and gave an error. The service center specialists saw that the replacement was made with an unoriginal lamp without a chip, as it turned out, the projector lamp would not work without replacing the chip. We have eliminated all the shortcomings. Many thanks to Master Vlad.
