My Sony KV-X2572U - Has it Finally Expired ?
About a year ago my Sony KV-X2572U developed a fault - if the picture being
displayed had white/bright areas, the colour temperature would suddenly rise (warm/pink on white areas), then drop away when the bright area disappeared from the picture (becoming blue/cold looking), before returning to normal - it was put into a local repair shop where they diagnosed (as far as I can remember) low output from one of the guns, which they said required a CRT replacement to fix. As the TV was still quite 'watchable', in addition to the fact that I was not impressed by the new W/S sets I looked at, I decided to stick with it until it became 'unwatchable' or it 'died'. Later on last year, I started, on occasion, to notice subtle black and red horizontal lines. After a few weeks, these seemed to largely disappear, and up until approx. 3 weeks ago, they were only visible on rare occasions. Recently, however, these have returned, being visible at various times on a daily basis, and more pronounced that they used to be. Yesterday, I switched the TV on and just as the picture began to appear, it 'skewed' slightly & sort of 'flashed', then went black. When I now switch on, the Nicam indicator lights come on, but no picture - after a short time, the light which normally indicates reception of a remote command, starts flashing. Has my Sony finally expired? TIA. |

The CRT is completely gone, going by your description. Also, there are
probably faults in the power supply, and or scan circuits, because you mentioned that the picture started to skew a bit. This would be an awful expensive repair, and well not worth it, if you were to do it. And, being an older set, future problems will not be predictable. Servicing your set would be a bad investment. If you do not like the 16:9 sets, there are some very good deals on the 4:3 HDTV sets out there. If you stay with a very high end consumer set, you will do well with these new sets. Always take an extended warranty with a new set. If it goes defective after the first year, it will be very expensive to service, if you do not have an extended warranty. -- Greetings, Jerry Greenberg GLG Technologies GLG ========================================= WebPage http://www.zoom-one.com Electronics http://www.zoom-one.com/electron.htm ========================================= "Kaal" wrote in message ...

No such thing here in Scotland, I'm afraid It is not the fact that they are W/S, but that they seem to have such poor picture quality, build quality, reliability etc. that puts me off I have never considered extended warranties in the past, but given the apparent in-built expiration/obsolescence in modern products, your suggestion sounds like a sensible option. A sad day indeed Now the search for a replacement begins, and I am not looking froward to it - is there any such thing as a genuinely good quality TV these days (50Hz analogue CRT)? I wonder if it is time to consider renting again, rather than buying??? Thanks for the replies.

There are a few things you might want to check. How many times does the light flash ? It should do a sequence of flashes followed by a slight pause befor repeating the cycle.This will tell you what the error code is. The set uses the AE2B chassis. There have been weird problems with the audio protection transistors going faulty, causing a dramatic loss of HT and the CXA1587S chip has been known to give the chroma problems you originally had. |
