Re: LG 60LB5200 will not turn on

Thanks, Unspun01. Today I picked up an LG 60LB5200 in the dump with a message posted that doesn't work. It had all the symptoms mentioned by the previous posters. Power supplies cold side has only 3 transistors and one ic which is an adjustable Zener voltage reference ic TL431A. All transistors checked ok in circuit. As the previous poster mentioned, I have replaced the q13 with a W1A SMD (2n3904 generic NPN equivalent) transistor and it works only to find the LCD panel has a crack.
