this set delivered today to my home to inspect and write report to company sold this set 2 weeks before and the customer reject it as it had fault at picture. its look the transport damage happened during the customer sending it back to the company or on the way to me.. who care its not may fault. LOL
this ULED had full array LED backlight. from first look after remove the back cover with dozens of screws as 2 part cover. i found the ribbon cable at the panel side they was not correct fitting in place ( see photos before take the T-CON driver boards & After.) my wounder which company in this world can pass QC for product at this condition.. and the worker who did it never notice that..!!??? any way the set made in (assembly) in Czech republic.
technical test: i did several test to this set to discover any further issue could face users and which sign of defect or errors sign.
Believe me this set had no any protection circuit in HW & SW at all...
A- if disconnected the 12V line from PSU to LED driver... the set remain on with sound and picture can be seen by torch.
B- if disconnected the UART ( yes its UART signal ) between main boards and led driver boards .... the set remain ON as above.
C- If this UART signal disconnected and just 12V line from PSU to LED driver boards.. all back light lit on in high mode. set remain ON as above.
D- if you remove one ribbon at time between T_CON & panel you will have half screen normal picture.( there is signal feed ) also if you remove both at once the set remain on with sound only.
E- if you diconnect the 1 or both LVDS between Main boards and T-CON the set remain ON sound Only..
tell the truth i never saw such TV even from hisense like this one.. its look to me good for DIY. hope this info could help any one in the future.
