Hi folks,

Have one of these where after a Darfon invertor transformer job, noticed that set came on from cold, always with backlight but no picture - from warm always OK.

Picture could only be seen after pressing S/by then on several times. Thought caps so heated most everything - made no difference, but S/by and on does.

Thought to attach piccy - any ideas - Chris.

Hi Chris,
            we have the exact same problem....I have changed the PSU with a known working one (from a TV that had screen damage).....no difference. None of the caps on the original PSU looked bad. In the near future I will organise a 'swop it and see' scenario using the other boards from the 'broken' one. (by the way thats where the stand I offered you came from )

   We found that the best way to get the picture is to 'turn on' from S/B using the remote ....leaving on for several minutes (ie no pic but sound) switch off....switch on ....and usually the picture appears. This is the only fault....everything else is fine. It is almost as if 'something' needs to warm up first ....will probably try the inverter board next and then the input board (scarts)

   As soon as I find the culprit I'll let you know

 Regards David

Hi Dave, and thanks again.

Nice to know that others suffer - Offering me your stand seems a mite pessimistic for a minor problem.

Have the feeling that as at least two of us are troubled by a Sanyo with a similar troubles, some helpful chaps will check a known european site and feed us the 'answer' 

Not 42, tried it - Chris.

Hi again Tulwar,

Would say Dave but 80% of Quuq so named.

'Stellaman' (Dave) suggested that caps C6661(10/16) and C6662(100/6.3) on main board under the FTV panel should be replaced. Did mine and all seems OK.

Think to attach a piccy as took a while to find 'em - Values were close but ESR rather high.

Pity about that stand but - All the best - Chris.
