I have had this TV for 4 years the 2nd year in early spring the TV just shut off. would not power back on. removed the plug for several hours and it worked again for several days thatn the shut happened again. unplugged wait 15 mins plugged it back in and it works this worked for a few years it has now been unplugged all summer long and would not work at all just last week I plugged it back in and it worked great for the day It now will only make a quick power up and shuts down immediately. If I go around and bang on the heat sinks I can get it back on for a limited amount of time. What could be wrong Bad solder?
I am finding out that these sets have almost the same problems mostly going back to middle power supply broad ck all connections,then try looking for leaky caps.
