Panasonic tcp4s60 went off following by single blink every 4 seconds
I try to find similar posts that apply to the issue on our tv but due to the overwhelmed informations here I couldn't find it. We have Panasonic tcp42s60 mfg Jan 2013, purchased Nov 2013.
Problem starts last year while it won't turn on but with single blink every four seconds. All I did was unplugged the power cord and plugged it back in, the problem went away. We weren't use the tv on daily basics so it happened few times like that until we moved it to my mother in law's room couple months ago. It works fine for couple days, then one day it went off after a minute she turned it on then single blink for every four seconds. I tried different plug-ins, tv performed the same. It turned on for less than a minute then went off with single blink every four seconds. So I unplugged it and let it sit for days, during that I called Panasonic tried to find out if any trouble shooting they could show me. Unfortunately the tv is not under warranty anymore and their was nothing Panasonic tech can help out on the phone. Instead of taking the tv to the repair shop and spend hundreds to fix it, I really try to do it myself in order to save money (if it's an easy fix).
So I openned the back of the tv and checked on the power supply board didn't see any capacitor damaged. The reason I did this cuz I found a video on YouTube saying the old Panasonic has similar problem could be burned capacitor on the power supply board. Anyway, since no capacitor was burned I plugged in the tv with the back openned, the tv stayed on for over an hour till I turned it off. Then today, I put the back back to the tv and plugged in, it worked fine at the beginning the tv stayed on for half and hour then I turned it off. Issue started when I turned it back on, stay on for less than a minute then off following by single blink every four seconds. So I kept unplugging and plugging, it worked occasionally. Even the tv stayed on but once I turned it off and turned it on again the issue started, so I had to do things over.
Has anyone had problem like this before? Your help will be highly appreciated! Thank you!
