I have a problem with this Sony 35" Dual PIP/Trinitron TV and I need to
decide if I should put the expense to repair or a get a new TV. Problem started within the first year 2002 where the video would just go black. The sound is ok. At first, it was intermittent and you took your chance then turning on the TV. But eventually, it went totally black. Since it was under warranty, it was picked up and "repaired." Authorized service invoice indicated a "Flyback Transformer" was replaced. When it was returned, it happen again. But strangely, it was not repeatable. In September 2004, we noticed it to begin happen again, and in December it went totally black. This time, being more savvy with the web, I checked the Sony web site and they had a FAQ showing the problem. The recommendation of unplugging the TV for 30 seconds seemed to fix the problem. The screen was back! Eventually, again, it went black. We were in the process of moving into a new Home, so we wanted to get settled before addressing the TV problem. We moved, put the TV in its new place, turned it on and for the entire month January 2005, it was working fine! But we never turned it off!! Well, for the last week its has been going black now every 2-3 seconds. If you turn off the TV, it may stay black. Unplug it, you get the screen back, but with this 2-3 second blackout. Here is the ODD thing. There are a channel that don't create this problem. In other words, if I put on channel 19, our local non-profit TV station with a "Bulletin Board" of town events, the 2-3 second blackout does not occur. Change the channel - the 2-3 secs blackout starts again. It is now 100% repeatable. How Strange! Anyway, I guess I would like to know if this is a known problem. Could it be repaired or I just swallow the lost of this TV and get another one? One thing for sure, I'm never buying Sony again. Thanks in advance |
