Sony Bravio line on pic

[Blackbiro]

Hi viewers.

My Sony Bravio Model 46EX520 has developed some intermittent horizontal flashing picture lines on tv and dvd playback across the screen.

Also there is a permanent very thin black horizontal line across the bottom of the screen at about 105mm from the bottom.

I have re-soldered most of the power supply/scan board, and also found a dry solder joint on the audio out socket of the signal processing board that made the speaker sound intermittent.

The tv is about five years old.

Any one had this problem with this tv before.

Tnx

No, but I a have a 46EX650 & I'm worried,
