LG	42PG20R	TV works for a few minutes and disappears audio and then comes back.	After replacing several capacitors that were getting very hot on the main board and removing the cold solders from the power supply board, I identified that the audio output was getting absurdly hot.	I did everything I could to replace components around the audio output and nothing was resolved. The solution was to place a notebook fan next to the main board. The TV has been working for 72 hours and tsound has been no defect.
