Title: LED sets with no picture
Post by: sinclairtv on April 02, 2015,08:24:44

Ive got a Celcus LED tv with no picture, sound ok. The PSU is a Vestel 17IPS20. Do LED sets have an inverter the same as LCD or in general, what should I be looking for with a 'no picture' fault  :sign0085:

Hi folks,

Only one I've met had a PS pop where kits are available, and sorted mine. Maybe a schematic - Chris.
