Re: Sharp LC-70SQ15U - Problem disguised as a 3-1 Blink Code ?

Mine was a 3-2 blink, caused by excessive current draw on the 3.3V supply provided by CH2 of U6802, a Rohm BD81002, 96-pin flat pack 6-channel supply & VCOM IC on the T-con board.
I pulled the right-side tabs on my LC-70SQ15U after troubleshooting to the corner cable and reading freakaftr8's thread on the vizio 70" failures. (before, with bottom right cable disconnected: thumb2) The bottom right drive chip was bad, judging from appearance of the chips on the ribbon cables (thumb4) After picture was restored...

Re: e701i-a3 no picture but backlights

SportsterPaul! I got a failed Sharp LC-70SQ15U in October (built December 2014) that had developed lines and gone dark, with a 3/2 flash code. NicksTV helped me identify the panel as the problem and the right side specifically. Pulling a bottom interconnect got me 3/4 picture, but with browning in the 3rd quarter. Disconnecting the corner cable enabled me to reconnect the bottom interconnect and get a whole picture, but with the right side darkening. Then Nick told me about this thread. Pulled the right side drivers and I have a good picture!...
