Re: picture bows on top and bottom of picture......

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 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

Help with RCA projection TV P46812BL (chasis ptk195AA)

You have probably blown one of the convergence ICs. Effectively the easiest thing to do is replacing the whole convergence board, so that no soldering is involved.

Here you can buy a replacement convergence board, just select your model.

Let me know if you need further help.

Bowed at top and bottom

No amount of cleaning is going to fix this problem, Go to menu look for setup see if you have convergences listed on menu if so try auto converge. If convergence is not on menu then you have a open fuse next flyback transfomer FL231 middle fuse.

The fuse fails when the convergence power supply fails,putting a new fuse in the set will let the unit come back on but convergence is not working,check in screens in the menu to see if you have adj. projection t.v.,if the is not in the menu,replace reg ic part number 215530 on the convergence power supply,this board is above the right module mounted on the black plastic.,hope this helps
