So we had this Sony XBR65X900B with a 4 blink error code. The service manual indicates that either a LD, T-Con, or panel are the issues. I had read in a forum that the main problem was the issue. Did the Display, 5, vol -, power to reset it, and update with USB drive. Didn't change anything.
After checking voltages noticed a couple of fets and a ceramic resistor were shorted on the power supply. Service manual didn't mention power supply as a possibility. After changing the TV came right on, and works perfect. Noticed a ton of parts on Ebay for this set that makes me wonder if people are scrapping these prematurely. Stupid 4 blink code was borderline worthless.
