Question about RCA F32649 32" TV
I recently replaced the Flyback Transformer on the TV and when I powered everything back on the colors are wrong. It's difficult for me to tell what exactly is happening, but it seems to be either missing one of the colors or confusing them. There was a problem when removing the old transformer one of the solder leads lifted off the PCB, though from looking closely at the board it doesn't seem to be connected anywhere unless the board has multiple layers. Does anyone know how to get a hold of the schematic for the the TV so that I could try to run a wire from the affected pin to the next component in line? Or anyone have any other suggestions on what to look for to solve the color issues? Thank you very much.
When you replace the flyback do you have to solder it or does it just plug into the board

It is possible that the degaussing thermistor fell out while you wer changing the IHVT. RCA is famous for the bi-metalic thermistor falling out or just one wire becoming disconnected. look next to the fuse and see if there is two wires sticking up with nothing connnected to them. If this is so, look inside the tv for the thermistor. You can actually repair it by burnishng both sides with a small file and then adding solder carefully while out of the tv, then brazing both leads to the thermistor. Also make sure if the chasis is a ctc203 that the inductor connecting the base is resoldered. This is the main cause of the shorted H. out and the shorting of the Ihvt. Always re-solder all suspect connections. 80% of all newer tv's problems are the result of poor solder connections. Since the formula was changed %lead to tin many companies have had numerous problems with wave soldering.Scrivitron
