I have an LG 37LC2D LCD TV that began shutting down and now won't display a picture. When you turn it on, the green power LED flashed about 14 or 15 times then stays on steady. The screen is lit but all black and the remote can only turn the TV off. In addition, the side controls on the TV do not work so it is not possible to change inputs, etc. Sometimes the TV will flash black and gray alternating. It was coming on after about a half hour of being powered up but it is no longer doing that.
I took the back off and as I expected, found a bulging capacitor on the power supply (PSU part number 6709900016D). It is C208 100uF 16V. I replace that cap but it didn't fix the problem so I am thinking I probably need to replace more of the caps even though they are not bulging. The output voltages are as follows:
should be 3.3V is actually 2.65V
6V is 6V
12V is 11.7V
19V is 18.7V
5V is 5V
Do I need to replace all of the smaller voltage caps or should I be looking for a different problem?
Thanks.
