Sony KVC2983
Hi,
I have a problem with a Sony KVC2983E. When I start the set it takes 5 minutes or more before the picture appears, normally this takes 30sec or so. All tips welcome Greetings, Patrick |

All tips welcome Greetings, Patrick I opened the tuner (BTP-EC411) and found it has been re-soldered in the past in a not very neat way! I think the best solution is to order a new Sony BTP-EC411 or the Philips equivalent UV916H tuner. Doe anybody know where to order one of those tuners in Belgium? Regards, Patrick |

All tips welcome Greetings, Patrick Do you get a Rasteron the screen , or blank screen? if it is a Blank Screen then you have a weak pix tube, and the delay is caused by the IK curcuit, which delays on screen , until all three guns are almost of equal output. sometimes you can just crank up the G2 Control just a tad and speed up the turn on. but you will soon need a pix tube. or replace the set which is mor cost effective |

The sound is OK and i can see the OSD in the right upper corner but it seems to be suppressed, if there is not much light in the room the green OSD is clearly visible. For the rest the screen is blank till it comes up after ca. 5 minutes. Greetings, Patrick |
