hi when you say it worked for 5 mins then green lines started to appear makes me wonder about the tcon .i recently had a toshiba which worked fine for about 25 mins then i had lines starting to appear and occasional pausing of pic but sound remained constant i replaced the tcon and it cured the fault

Hi folks,

Notice that board numbers and piccies are a bit absent.

Feel it's difficult and almost pointless to try diagnose probs without any useful initial input -

Just a thought as have needy Demijohns to flush, and wine to check   - Chris.

Not quite sure what more info I could add. The picture I posted is a good example of the problem (that guy isn't supposed to be covered in green slime or anything..). Periodic clicking sound, vertical green lines, lots of green noise on black pictures, chronic symptoms.. are board numbers really that useful? If so, yes, I can list them.

Well, anyways, this morning the tv started to work just fine, with all the HDMI inputs, without anything changed since last night except going through the test patterns from the service manual (from the factory menu). IT's been stable since then without any sign of green lines. The only thing that may have changed since yesterday is a slight drop in temperature as it's noticeably cooler today which could point to faulty PSU or similar component.

As the problem is sporadic I'll investigate the cables and Tcon first in case it comes back. Thanks all for your input. I may not need to buy a new tv after all!

Hi Librex,

Not intending to be difficult, but problems tend to be localised to specific panels, where repair folks may well have some data.

General problems with no useful information tend to gain vague replies.

Cool, if Vague is your biz - I try go for Panel numbers and piccies - Chris.

Hi, 9 times out of 10 from my experience this sort of problem on all lcd`s is cured by simply unplugging the cable from T-CON board, (the small board on the back of the lcd panel) and cleaning the contacts with a suitable cleaner.
 phil,
