I Agree with willtab with the color wheel. Is really suspicious, once this servo motor is defective is a common symptom. Now the bad news is the color wheel is the heart of the light engine. (Kind of a piston in a car) i mean not a simple procedure to replace. This job is good for a technician in the bench.

Two possibiltes. A bad cooling fan or what is known as a color wheel. is this a whining sound. does the colors flicker. a bad fan could have contribited to the bulb going out too. to identify a technician would have to take back of and examine fans and listen

I have av RCA RLDED5078A-D 50In LED I was watching it and the screen went black but I can still hear the sound!!

Probably the power supply board went out or the backlighting.
Unlikely it's the control board as the sound is still working.

Don't open up the TV to fix it yourself if you don't know what you're doing. There are HAZARDOUS voltages inside EVEN WITH THE TV UNPLUGGED!!!.

Find a couple of shops, get quotes, try to find reviews of the shops too. If it's still under warranty, by all means contact the company to get it fixed.

Have a RCA M50wh74s replaced the light blinks 5 times again and again eventually a steady blinking all blue light bulb in correctly, door closed correctly, any suggestions and I have sound.

Bad Caps on the AC IN board? I would visually inspect the caps on the AC IN board for any sign of swelling or doming on top. They should be perfectly flat.

I have an LG 50in 1080p Plasma tv. We turn it on

Many of these unuits were recalled to have the power boards replaced, the 42" model was a class action court case . The reason your set worked after sitting for 2 days was because unplugging and leaving a for several hours was equivalent to a hard reset. Try doing that before you submit for repair again. It will probably fix it temporarily again.

The power boards were made in China and have been faulty workmanship. Try laying a claim against LG even though you are out of warranty. I would as they know this problem existed with many of the models they flooded onto the market.I would never buy an LG product again

When I push the power button on my RCA HDTV R52WH74, the green light turns on for about 5 seconds and then off. NO sound and no picture.

Sounds like the bulb went out.
Go to and order a new bulb for under $200.
They are easy to intall; a screwdriver and 10 minutes.

You need a new bulb or fuse, as yours went out. If under warranty call the warranter. The tv should have lights on it that blink if it is a bulb, my samsung does this. If there are no leds on the tv, ie the standby led is off, then its your fuse.
