Sharp 28" TV Fault
I have a 2 year old Sharp widescreen tv (Model 28JW73H). It has
performed faultlessly and has a great picture. Just recently the screen has been playing up with a intermittant picture fault. The picture is still there full sreen but basically the screen is all washed out with green wishywashy colours. It then works fine again for a while. The picture is now permanently green wishywashy. This is there on terrestial tv satellite tv ps2 video and camcorder - I checked all inputs ! - all plugs seem ok and in tight - wiggleing of each scart does not lead to improvement in picture. I have also just noticed that when you turn the tv off the screen goes black and then a red green blue flash appears for a few seconds before disappearing. Any advice would be gratefully received - I presume this may be a tv repair shop job ?. Thanks. |

There is a good chance that there is a cold solder connection in the video
path where the video signal is processed. There is also a chance that the CRT itself failing, and has become intermittent at times. The TV shop technician can verify all of this for you. -- JANA _____ "TONEEBEE" wrote in message oups.com... I have a 2 year old Sharp widescreen tv (Model 28JW73H).
