CV358H-A50 Board stanby mode
CV358H-A50 Board  , the problem was  when switch on the tv  stuck on logo. It,s software issue so I try to upgrade sotware by usb . When it was upgrading, error occured and tv go to the stanby mode. Again I try to upgrade software by usb but it,s not upgrade, It's remain in stanby mode. What should i do now, How to solve the problem????
Dear in such cases JTAG is required by RT809H programmer

or in case of memory chip fault

the second solution is to replace the board by yourself

if you visit any technician, he will charge too much
