Usually the singing ir whistleing you hear is a capacitor. Usually the ones that go are in the power dection or high voltage as they get worked harder.

They can be easily fixed but you have to identify them first. Your repair shop may be able to figure out which one by the sound. The other way is to actually let it go pop. then they are rather obvious.

What I would suggest is to call a few repair shops and see if they want to track it down when its singing or if they want to wait till it goes out. Sometimes this can take a bit longer to find so they don;t want to spend the time. As well get an estimate before getting it fixed. Know what a replacement is worth just in case. This should be a cheap(ish) fix but depends on what goes out.

So it should be safe until it goes out but may cost more to fix if you let it go as it could do more damage.Or it may cost a bit more to fix if they have trouble finding it. So its one of those can't win for loosin problems. If your repair guy is sharp I'd take it in as soon as I could but wouldn;t worry too much if I couldn;t.

No HD pic on Samsung HP-R5250


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Take it to a repair shop.

About four years old Samsung LW26A33W 26 lcd tv (1500 euros) and power went out suddenly while I was watching it. I then had a tech give it a once over and he claims the power supply box should change, and...


We bought a new one. The old one went to basket. The seller gave the new one little bit cheaper.
So its nowadays. Much more rubbish! The way to solving this problem was the baddest way.

High pitch noise


Hello there, You have to specify where the noise is coming from. Is it coming from the speaker or from the back of the unit. SMPS power supply powering your unit create this kind of noise when some capacitor gone out of their value.

Good Luck.

Set TV to standby and press Info, menu, mute then power. The set should turn on with the service menu available scroll down until you select reset press right hand arrow next to enter and then enter. TV will turn off. When switched on it goes into Plug and Play mode to reset the analogue and digital tuner. Allow a full reset then you should be ok.

Need help


ensure the tv is in analogue mode, not dtv and turn it off. with the remote: press info then, menu, then mute then power. these buttons need to be pressed sequentially not all at the same time and in quick succession. a menu will appear on the tv. navigate to the reset option and press the left arrow key on the remote (or press the enter/ok button) the tv will reset itself and turn off. turn the tv back on & it'll re tune all its channels. DTV should be working again.
