I read my chip with FlashcatUSB with NAND adapter but the file I get is 131.072 in size and your one is 135.168 and even if I try to write your files it will not write it all because the programmer can write only 131.072 as this is the maximum size the programer detect according to this chip which is the same as your one H27U1G8F2BTR and the tv doesn't work, only 11 led red flashes. With his old files the tv powers on only sometimes and sometimes only the front green light flasher but the board doesn't turn on again after I power it of. The other 2 chips size you posted are ok. Please advise. It can be my programmer faulty as is detecting a slightly diferent chip size? Or your one is reading some hidden area on the chip? Thanks in advance.

Don't worry, I manage to sort this problem. I had to combine the chip main with spare area on programmer protocol settings and now the read write size operation is matching with your one.
