Re: Samsung UE65h5400AW Won't Turn On (Has Red Standby Light)
there are some TVs (Samsung) that drive the LEDs only with the power supply, if it is the case of yours you can disconnect the main card from the source and leave the LEDs when applying energy in the source; this must drive the LEDs alone, so that it is useful if you have a problem on the main board, by not using it the starias discarding by default .. ps: when the LEDs are activated in that way they generate 100% of the brightness, they do not blink just turn on like a common lamp

Canon Pixma G3111 no power
In the first turn on with error (E04) referring to some printing head problem, when opening the cover I saw that something was blocking the printing head, I decided to disassemble to see if it had jammed and do a routine maintenance, when I put everything back in Your site did not turn on anymore, the source seems to be fine with 8.29v stable in the capacitors, I also read the same voltage here you can collaborate
I think it could be a bios problem, you have more experience than you can point out -

Re: Samsung UN32EH5300 BL on no picture
In the tcon you have two LEDs, one that indicates that it is receiving 12v, the other led usually more to the right indicates that it is on, with a bridge between the pins of the two ends where the two flex cables that go to the panel are connected. you can make it work i send you images.
THAT WAY YOU CAN SINGLE A CABLE FROM ONE SIDE OF THE LCD PANEL AND ALTERNATE...Leave a comment:
