Question about Sony KP-57WV600 57" Rear Projection HDTV-Ready Television
Hello everyone. My dad bought a KP57WV600 tv that had a known convergence issue with the red CRT. I've since repaired that problem by adjusting the voltage pot for the red crt. After that though, the picture still didn't look right. Things that were supposed to be blue were greenish and things that were supposed to be white were yellow. Because of that, it appeared that blue CRT was not on. I opened up the back of the TV and sure enough, it wasn't. To make a long story short, I do have voltage to the CRT drive board, but there are at least 2 blown components on the board. So, I'm assuming at this point, the board is blown and this is the reason the blue CRT is not coming on. I'm an electronics student in my final semester at school, so I know a little about what I'm doing on the boards . However, one of the components that is blow on the board, I've never seen before and do not recognize the schematic symbol. I brought the schematic to one of my instructors along with a picture and he said he thought it was a indicator lamp. In my schematic manual, the lamp is listed as NL9302 and says 80V below it. The other component that is blown is the 1k, half watt resister that is in parallel to the lamp (R9323). The 1k resistors are easy to get a hold of. The lamp on the other hand, I'm not sure where to get it and even then, I don't know what amperage it needs to be.
So A) does anyone possible have a good CB CRT drive board p/n 1-685-260-11 board I could buy or B) does anyone have an actual part number for that lamp and/or know where I can buy that lamp and what the correct amperage is on it?
Thanks a bunch!
Just look on Green CRT Board they all 3 boards have the same parts you can connect other crt board from other tube to blue and turn set on.
