Swisstec EJ20 stuck in standby (possibly AOC / Yusmart)

Hi Evilmrb,

Note they don't offer service info, just thoughts for folks who have trouble pushing buttons and still seek  cash for new crap.

In the old days, the (British) factory sent a technician - FOC to sort initial problems (sets lasted at least 20 years) or 'till woodworm got them.

Admittedly in those days (50's) TV sets were total crap but we earned up to £7.00 per week, making us high flyers, laughing at electricians, plumbers, and lino layers.   Times change  - Chris

Anyone with a dime or a double 22 to 14 coupler   ?

Hi turnip,

I got in contact with them  today over this UMC LCD i have,but would not give me any info just said if i sent the set could be any thing from £49-£150..wouldn`t mind but the set only retails for £149.99 in Tescos.. :41:

I've done some probing about with the 'scope.

The Power On / Off button connects directly to one of the pins on the socketed eeprom.

Scoping about all the pins on the eeprom shows some high frequency logic activity on just a couple of pins, all other pins sit at static logic levels and nothing changes when pressing the power on button.

That does not sound right to me, I would have expected a lot of logic activity on most of the pins.

My gut feeling now is to scrap the set and sell the psu and inverter, being the only bits that are easy to prove they work.

Any further suggestions?

Hi PD,

It's my Swisstec 20" LCD television model Sky-EJ20/w/CG, the one the subject of the original post and thread.  I had some time to do some more probing about and was surprised at the lack of logic activity on most of the pins of the eeprom, leading me to suspect there's a lot wrong with it, and I was asking for more advice.
