Hi Chrissy,
Folks say 20 / 22nf does the job, never tried but - wouldn't worry too much - Chris

chrissie jones:
thanx turnip...but i used 15nf instead of 18nf and all works fine.

mali67:
caps arrived (cheers chris) but still same problem , screen flashes on then goes off

watteau:
Hi,
If you've still got the 24v inverter supply when backlights go off, you
could try Q841,D861, or C904, off pin 12, PL802 (the backlight on/off).
Does this voltage change when the backlights go on/off?, possible main pcb
switching inverter off.
Regards,
John
