Have a phiips tv had it in storage for over a year turned it on an the screen working perfectly but there a hising noise coming from the back of it do no what it is... Its a big bk tv not flat screen box...


hissing noise will be from high voltage regulator, i would suggest to do following:

1. switch tv off
2. remove plug from the wall
3. using air blower (compressor attachment - not leaf one!) blow the dust, especially from high voltage box section
4. connect the tv and switch on

if tv still issue hissing noise - follow 1 and 2 then:
3. remove back cover
4. use air blower again...
5. re-install back cover
6. reconnect tv and switch on

if hissing noise persist - check for blown capacitors on high voltage, replace if necessary, they have nasty tendency to pop if they are too long in storage, especially if tehy were overheated or frozen.

hope this will help you solve the problem, do not forget to vote...

White line across screen


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.
