Question about RCA P46924 46" Rear Projection Television
Hello i am very new to this forum but any help is apreciated. i found a Rca tv and the only thing wrong with it is the picture bows inwards on the top and the bottom .....where can i get info i need to fix this myself.....(service manuals,schematics....etc.) on the back of tv it says service no. = P46924YX5 MODEL = P46924 SERIAL NO = 051441559 CHASSIS NO = PTK195M2A i tried looking for the convergence menu also but it doesnt seem to have one......which puzzles me ....
Hi my asteamed coleage is correct in most cases.I have been a factory warrenty tech for rca since 1985. your set ctc 195 chassis has 2 boards 1 digicon board (digit convergence board) and 1 small convergence board called conver power supply) this board produces power to digicon board There is a pos 47volts and neg 47volts along with 15 volt supply ) i think if looking from back of tv (with back off) in the upper right corner you will see a small green board (4inc long by 2inch ) on that board is a silver metal piece going from top to bottom is a small black (kind of rectanggular black chip it has a clip ontop remove screw to see num on chip is 730-020 change that . as for your ques about customer convergence it's hard to find if you hit menu move down to vidio menu (you will get color,brightness and so forth but keep going down it will come to CONVERGENCE hit + key hope me and colleage helps fix tv from MILWAUKEE WIS HEY GOOD LUCK

Your problem is the convergence IC'S. They have STK ###-### the # are numbers. You can get parts at http://partstore.com. If your not a tech and an experimenter or a handi person Pease be aware of the hi voltage inside these sets. Also be aware your going to need to unsolder and resolder the ICs in and from the printed circuit board. Good Luck

The first three are fine as long as they are the same.. Its the last three that will matter too. If the last three are 120 no you mshould not use an 020.. It will work but will not hold up long.. If the last three are 020 yes you can use the higher numbers to sub the lower as those numbers are the wattage output of .the IC
