Title: Orion TV32PL12
Post by: sany on August 24, 2014,18:02:50
Hallo,
I have LCD TV Orion Model TV32PL12 (Power supply:CEF273A-6 ETL-XPC-204T;Main PCB:CMF111B4 DB040_70720A).I haven't schematics but i take service manual of Sharp LC32AD5E-BK because it looks the same...The Problem is no power led,no start.Both fuses and voltage 5V on the power board are ok,there is no bad caps... Any ideas what can be wrong and what should i do? :sign0085:

Thank you very much Jordan,i will check them all carefully.I was confused,there is no PS_ON that typically turn on the IC. The power supply is powered up when the main board turns on the power relay...
Greeting

I checked power board and everything's ok....The service manual of Sharp is not the same as for Orion...I found another - Toshiba 20w300p and this is identical with Orion...I need to find out where is the power failure on PCB board...
