    Thanks. My TV power led flashes two times a second, and OPC one time. I checked its service manual which has a led flash times code. It describes it could be a 3.3V voltage not detected.

    That low voltage suggests a micro processor or standby circuit issue.

The set is in shutdown, possible power supply or a short almost anywhere in the set, if not technical best idea is have a repair shop look at it, if have skills here I would begin by checking power supply voltages inside the set and looking for the bad caps that are common on a lot of these sets.

3 times standby red light blinking shows that lamp cover has not been placed back properly after lamp replacement.
Make sure lamp cover, (the first thing that you removed to replace lamp in tv) is fixed securely then turn tv On.
