    yes... but this time packing the boards complete at the kitchen often ... with high temperature and dont use air flow function .... or if you have toaster... etc... maybe the the BGA at the sandwich ... who knows... so better we go with this method

      Are you joking, mate? Do you want me to put the board in the toaster?

                    if toaster.. then the following
                    1- prepare the main boards
                    A- cover all sockets ( plastic ) with Aluminum Foil.. be sure the foil didn't touch the sockets such scart... audio Optic Out. LAN, video & audio in plugs , CI decoder
                    2- Test the boards size at the toaster to locate best place you will put it inside on plate
                    3- turn on the toaster full temperature and wait until it reach high temperature as the plate too
                    4- place the boards on the plate and close the door for 10 minutes if the temperature are round 280 degree
                    5- turn off the toaster.. carefully open its door with out let the boards shocking or moved
                    6- wait until its cooling down than take it out..
                    good luck

                      Hi apologies for late reply .

                      Please don't cook the main CPU .

                      Far as i am aware , this set suffers with EMMC chip issue & yes the company i mention microtech , based in Bolton can sort it .

                      Regards Zen

                              Yeah i sent them email 2 days ago and the answer was:

                              Main emmc faulty we dona service for this model please be advised no netflix or amazon prime or chromecast apps are down please use fire stick which is 100%
                              Then my question was "How come without Netflix etc.." and they answered me:

                              Sorry if you want 100% working board please buy 1 on ebay to replace it we only repair the board with few apps that do not work that we advice and have plenty of our customers who take the service anyway good luck all the best
                              So, not much helpful....

                                Sorry Diah , i'm just trying to help .

                                I won't mention any companies in future , that i believe can help resolve the issue .

                                The EMMC chip holds the full android operating system , and when data becomes corrupted , it can cause many different fault symptoms on TV .

                                  Pictures of board are not clear , but the chip i mentioned is either the B G A type below the optical socket , or it may be under the white ceramic plate covering the CPU .

                                    its okay..

                                    MT5830BPHJ are the brain of this set it control all function.. include the IR.. if one BGA POINT get OPEN this function will be error.. IR are function and here we have the case. who knows which POINT.. but we still can guess the side of the chip where the OPEN POINT are.

                                    actually if the OP had Air Mouse the procedure will be more easy after he pass first installation then activate the developer Option & USB Debug so we can with adb proof the IR function.

                                      Main CPU could potentially have poor ball connection issue , but it's just not something i have had on this specific model .

                                        OP did many time hard reset.. it mean the NAND being erase and the Firmware again extracted and wrote back to the active partition of NAND. if there corrupted sector at chip for example it will not pass the erase. and if some one think the firmware corrupted , the firmware cashed on protected level. no access to any app or user to change or delete... beside it extracted correct after erase. the only things left the CPU.
