Swisstec EJ20 stuck in standby (possibly AOC / Yusmart)
ProDave:
I have a Swisstec 20" LCD television model Sky-EJ20/w/CG
Fault is stuck in standby.
Googling suggests it's made by Yusmart, here it is: http://www.skwd.sk/yusmart/products6.htm and it's also quite probably sold under the AOC brand.
Numbers on the main board are: N2010E JC206H63E 2202519 400 Rev 1.00
Any help or pointers please?
The PSU appears to output two 12V rails which are both okay. There's also a clearly identifiable +5V derived from that on the main board that tests okay.
Standby light is illuminated yellow, but does not change colour when trying to turn the set on, nothing happens at all.
I don't have any service information at all.

Hi Pro Dave,
In the event of nothing better forthcoming, a piccy would be useful as we might know and curse it as something else.
All the best - Chris.
ProDave:
Good idea. Picture atached.
One thing I did try was removing the eeprom, and without the eeprpm plugged in you don't even get a standby light. With the eeprom in, the standby light comes on about a second after you plug the power in, so that looks to me like the processor is operating.
I have identified 12V 8V and 5V power rails all working, but haven't located a 3.3V rail, but being an old set it might not use any 3.3V?

Hi PD,
After that build up, and with cool voltages, guess we're all gagging for a piccy. - Chris.
PS - see you've just added a piccy, looks cool, esp power, capwise, haven't seen it before, suspect prob might be in EEPROM area but have no info - thanks for piccy - building a file - Chris.
