Hi guys: I have a Panasonic Model CTH-1942R (a little old) and have no schematic for it,is Sams 2538. The problem is that is out of hor.sync but if I lower the input to around 80v will play ok,so I think that it is not regulating ?.I replace q801 (scr) and check caps around but dont find anything wrong,even check resistor and are ok.If somebody could send me the regulator area to verify or any tips I will appreciate it. TIA and have a good weekend. Jorge. Jorge Miret-Puerto Rico J.C.Video & P.C.Repair Tel:787-761-0920. jmiret@xxxxxxxx ------------------------------------------ Make your TechAssist database better!
