Re: Philips 70PUS6504 without picture
Thank you for reply. Indeed that is what i taught but these dots are seem to be different places. On one screen they are solid, change picture they move to other place. And lined that show up as well sometimes there is more sometimes less. I think its a panel myself but just wanted to confirm before i scrap it.Leave a comment:

Re: Jmb 32/68g-gb-1b-tcdu
Its a blinking STANDBY light. Once I try power on tv the red standby LED starts blinking. It's the JMB 40inch... sorry cannot remember model from top of my head. I have removed power board and found one cap that looks not right (bulged at top). I have ordered replacement and awaiting it delivery today or tomorrow.
Other than that read on forums that JMB models have same symptoms when EEPROM corrupted so decided to give it a go as well.Leave a comment:
