Greetings Friends, this time I would like to ask you a question. It turns out that I have a Panasonic Panaturbo Model CTG2159E TV. To which I changed the screen I replaced an A51A that he brings with an A51A from a Magnavox TV. I changed it because the original one was a little stained but it looked more or less good and with the new one the TV gives me a white screen, green and delay lines stand out and this screen was perfectly fine. The voltages are at 242 volts in KB KG and KR I already check voltages with the video board disconnected from the tube but they are the same at 242V: They advise me. Thank you

Hello Friend. regulate the scren of the flayback a bit and check the 3 largest resistors that are on the trc plate. and check the 3 transistors that are right there in that small square where the socket is but if you already did the test with another screen and improve you have to change to another screen because that is bad. luck and. Cheers

Good morning thanks for the prompt response, try the plate on another screen and it looks excellent, which leads us to deduce that the screen would be the problem. My question is: Is it damaged while being saved? I say it because I saw it on a while ago and it looked great. The pin configuration of the screens is the same with the difference that the H and HGND are reversed, which I think does not matter since the filament has no polarity
