Sharp LC32AD5E-BK Vertical lines when cold

[andyturbo]

Sharp lc32AD5EBK when you first power on displays bold vertical coloured lines which fade in and out and change colour, completely dissapear after 10 minutes or so and then picture is perfect and will stay perfect until you turn off and leave for a while. If you turn off and turn back on no problem.

Have tried replacement PSU which made no difference.
Have tried replacement tcon which made no difference.

Wondered if anyone has come across this problem on this, or any other make. Please see attached photos. Any help would be appreciated.

Maybe a faulty panel - was it your set? - cleaning fluid run down the front? have you inspected the panel?

No, only had this set for couple of weeks. No I have not inspected panel. Thought it was bad caps and had spare replacement board so tried that same with tcon. I will have a closer look at panel.Thanks.

Checked panel and tabs to panel and reseated two ribbons to tcon. Turned on straight away. Waited till next morning turned on and same problem. Turned TV off and back on 10 minutes later turned on perfect straight away and now will not show fault . frustrating intermittent problem. Will leave off and try again later. When on perfect picture.

Beginning to look like a poor solder joint somewhere - bugger to track down. May need to arm yourself with a hairdryer and freezer spray.

May be a dodgy voltage regulator on the tcon.

Yes, I think so, although seems to be working better after looking at panel. Left off for 4 hours and started up straight away no problem. I will keep looking. Thanks for your help.

It is certainly a bad panel. I have one identical.
