Question about Samsung LN Televison & Video

1 Answer

How do I troubleshoot my Samsung TV? I have sound, but no picture.

I took the back off of the TV. Checked the capacitors. None of the nine capacitors have bulging tops, leakage on the top, or any corrosion on the bottom or top of them. I think the power supply is OK. (Red light goes off and on.) Perhaps I need a new T-con board? Can't find one for this model online. Thank you.

Caps can fail with no outward signs. It takes a special meter to test them. Your set may have a back light inverter that powers the back lights. When it fails, the picture cant be seen, but you have sound, to check this look for a picture on the screen using a flashlight

60pa6500 LG Plasma NO sound or picture. Standby RED LED lit, when I hit power I hear a click and RED goes off. Checked caps on all boards visually and none are swollen.


Check capacitor with a digital volt meter. In my Samsung, the TV has a chip that check to see if all circuits are OK before turning on the set. Samsung has a power, input and video boards. The problem is when it check the high voltage circuit and it does not have 390 volts, the chip turn-off the power instead. (It is a safety thing.) You can buy a new power board or fix it yourself. The power board is where the 120 volts AC is plugged in, and near the 120 volts is small transformer, then you will see a capacitor rated 100 uf at 450 volts. Check for 390 volts here. If the voltage is less, then replace this capacitor with a 350 uf at 400 or at 450 volts.Samsung used a "small" capacitor when it should have ordered at large capacitor. Good luck.

My LG 42LH5000 TV is not turning on. A few days ago suddenly switched off and now it doesn't turn on. The red LED is always on. If I unplug it turns off and when I plug again the LED is red again.


I had the same problem with Samsung. A web search located the issue being the capacitor. Take out the back and look for the capacitor near where the power line enter the TV. It was a 100 uF at 4050 volts capacitor. checked the DC voltage to be 381 volts. Got two old capacitor from an old TV - one was 150 uF at 400 volts and one was 220 uf at 400 volts. It turned out that it needs two in parallel (making 370 uf at 400 volts. Took out the under rated 100 uf and replaced it with these two. Checked the voltage to be 390 volts. That did the job. Samsung must have tried to save money by putting in a 100 uf at 450 volts. .
