HOW TO FIX A RCA scenium power suppy - RCA Scenium HDLP61W151 61 in. HD-Ready Television

Are you using RCA type audio cables?, if so, make sure the connectors are tight and the cables are not frayed, it also helps routing those analog cables at least 8 inches away from any power cords or transformers. Buzzing usually is caused by loose ground connections or RF interference.

it may just be components on the power supply board have small breaks that keep power from flowing until the board warms up and the breaks are closed.

This repair will take someone with a knowledge of your tv and a good eye to inspect the circuit boards. The plus side...it should be a simple fix once the breaks are found. Keeping costs to a minimum.

Good luck and be careful

Power supply is getting bad.

If this is a DLP set, which I suspect it is....you need a new color wheel. Common problem for these sets. If you don't have an extended service plan, about a 300--400 fix, in home.

What does the picture look like when it is on?

I had the same problem with mine. It was overheating. I installed a small cpu cooling fan on the back of the unit. No problems since. Good luck.
