Toshiba 43T6863DB Weird Backlight Problem
My two year old Toshiba 43T6863DB 43" TV has an intermittent fault that has baffled local repair people.
The backlight fails, but when the TV is laid horizontally and the back panel removed, it recovers. I initially thought this was down to cable jiggling, and that there was a bad edge connector somewhere, but now I'm not so sure. Once the backlight is back on and the TV replaced it works for a while - maybe a few hours to a few days, and then it fails again.
When it fails, you can remove the back cover, do nothing else, then replace it and it works again. This is not a repair strategy I want to continue with!
Has anyone seen this fault and any thoughts about what might be causing it? My pet theory is that this is a dry solder joint somewhere - in which case, where should I look to try to reflow it?
Thanks!
