Osd | Kp53xbr200. unit will not loose the on screen display data that shows the program material, length of time, type or program, rating, ? etc. | This is the xds (extended data services) information that is broadcast in the vbi. it is selected of the customer has the xds feature turned on. we could not turn this unit off. suggest tech to enter the tech menu and initialize the eprom by pressing ""8"" the ""enter"". this corrected the symptom.

No raster | Kp61xbr200. no raster but has sound. unit will operate for several days then loose raster. during the episode the timer led will blink as it does during the warm up sequence | The led is blinking 5 times. this is an indication of a ik error. since it is so intermittent i suggested that he could replace the a, cb, cg, & cr boards. these are covered by the s.a.y.s program. it is possible that a tube is causing this trouble but we cannot confirm it unless we see the symptom. the replacement of the boards is an attempt to eliminate 4 possibilities of the ik generating and sensing circuit. | Muller |
