Hi friends ..
Another longshot ...
Another Cheapy supermarket TV
This Time a Technika X22/14E
Mainboard type T.SP9100.2C
9315
The set is working ...but displays message 'database empty'..
Selecting scan for new channels finds nothing ..
Reset an first time install ...again finds nothing scanning freeview ...database empty..
The set goes through the motions ..displaying a scan progress bar ..but completes far too quickly ..approx 10 seconds full scan ..
Exposing the main board it was possible to check for supplies on the tuner ...but nothing above 3v on 2 pins ..and nothing on the others.
I have no circuit ..and cannot identify which tuner pin does what..
..but I'm sure this is a missing tuning voltage ..which shoud be at least 15>20volts
Of course ..its impossible to investigate and search for a missing supply line easily ...as there is no service info ..either for the main board ..or the XuYang DTT-8S1C/T1146 Tuner unit..
If anyone has service info ...manual ...or just a schematic I'd have half a chance ...
Anyone??
The last resort is to ignore the tuner and fit a freeview box ...but the customer is a 95 year old lady who has enough problems just using the TV ....adding a freeview box and another remote ..would have her totally bewildered..

Hi evan
No info per say however if this is any good to you cover P&P and your welcome to it. I will say however I have absolutely no idea of the boards provenance . I believe its good or I wouldn't have kept it but its a roll the dices and take your chances senario

Cheers Jim ...
The owners son is calling in my shop tomorrow ..
I'll run it by him ..and hopefully he'll agree to have it done ..rather than go down the freeview box route..
I know thats going to be an issue for his elderly mother.
You have my email address from the samsung pcb discussion ..
Just email me the amount you want ..and I'll hopefully get back to you with an 'all systems go tomorrow' evening ..
Paypal ok ?
Very much appreciated m8

Thanks again Jim ..
Panel arrived this morning ...
Sadly customer got impatient and took the set away to use on a feewview box over Christmas ..
At least I got to keep the deposit ..and half a promise to bring it back in the new year...so hopefully I'll get to try the panel in it then.
In the meantime ..I've removed the flash chip ...read it ..and added it to the database ..
(labelled untested) ...but with a pcb photo
cheers m8
