I have a Samsung HL-R5677W TV set and now there is no picture at all. Every time you power on the TV the green light flashes and you hear this sound that repeats itself. It sounds like a camera flash, low...


I have a few questions which will determine what your problem may be.

Did or does the set make a high pitched fan like sound or a high pitched whine?

What have you examined so far?

As far as a lamp it is unlikely it will cause such a sound but if you remove it look to see it is intact and not shattered.

Let me know

High pitched sound


The high-pitched squeal is from the power supply, usually because of failure of the horizontal output transistor, flyback transformer, or both. Without a specific model I can't give more definite information about part numbers or likely costs. But repairs of this type usually have parts costs in the 10 to 75 dollar range (depending on just which parts are bad, and where replacements come from) plus whatever labor costs the repairer charges.

High Pitch Sounds


In this model the horizontal drive coil vibrates and makes a high pitch squeal. Most times it is intermitent. Touching on the coil with something (non electrical, like wood) will make it stop or change it's pitch. The fix my shop uses: It's not to technical, but, we put fingernail polish around the coil. It's a remedy I've used for decades and has always worked. Some shops use a hot glue gun. With the back open you can hear the coil to locate it. When fixing the problem have the set unplugged. When a technician is working on a television while it's plugged in. He uses only one hand and stays away from the high voltage.
