RCA P52936, CTC 195R2 Projection T.V.
Had keystone pix, & very poor convergence, customer totally adjusted
the advanced customer convergence menu. CR14800 leaky, & C 14800 had a bad connection, & arced out straining CR 14800. Rapaired the set, & did a full convergence, picture tubes are all blurry, & raster is quite bright. Even with the red, green, & blue G 2 set to zero, there is still a visible blue raster. With minimum settings of all three G 2, to get a grey scale, the raster is still bright, with contrast, & brightness set to zero. Just like when you put a new flyback in on of these sets. How can I make it less bright, & washed out? How do check how many hours are on the CRT's? Isn't there a warranty clock on some of these units? Thanks, Dani. |

Sounds like the AKB auto adjust needs performed using Chipper Check. |

You need a chipper check -- it will allow you to see the usage log on the
micro. It sounds like your eprom could be corrupted. With the chipper check you reset the eproms to default. Try going into service mode and read the error codes that will help to determine the problem. Best regards |
