This is a common problem with older Philip Magnavox projection sets. Over time one of the IC chips on the main power board begins to fail. You can find replacment chips and repair instructions on www.magnavoxhelp.com.

My samsung HLT5075s has a popping sound coming from it. The sound comes faster and faster and then the tv makes a Bleep sound and shuts off. Do I need a new power supply or a ballast? The picture is...


I had this problem too, popping coming from the internal speakers it seemed. I typically use my surround sound so the internal audio isn't necessary for me. You can take off the back and down next too all the inputs on the right hand side (if facing tv front) you'll see a little gap between the connector housing and the base of TV, there is a little cable connected to circuit board that is red, black, and yellow i think, pull it from circuit board. this disables audio from the main board traveling to front of TV. Problem fixed. Ps ..this also cuts the red led in the front..

My philips 50p8341 beeps then flashes the red led 4 times


4 Blinks means that an incorrect voltage had been detected on the +5V circuit coming from PSU to digital control board.
The PSU must be tested and eventually repaired or replaced.

TRYING TO HOOK UP MU POWER BUTTON NEED TO KNOW


Hi there
The front panel connectors are mainly,
  • harddisk activity connector
  • power switch connector
  • reset switch connector
  • power LED connector
  • speakers connector
  • USB connector
Harddisk activity connector
This normally comes red in colour and is labeled as HDD-LED
Power switch connector
This comes green in colour and is labeled as POWER-SW
Reset switch connector
This usually comes grey in colour and is labeled as RST-SW
Power LED connector
This is usually green in colour and is labled as PWR-LED
Speakers connector
This speaker will give different beep sounds during boot to tell the user if there is any errors. It occupies 4 pins, however only 2 is important for the function. Be sure to connect the red coloured cable to the positive polarity and the black to the negative.

No Picture & No sound. Red LED, Green LED, Red LED.


If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.

No picture, however there is sound


Is this set hooked to cable? Is there a cable or satellite box? When you press the menu button, do you see the menu on screen? Do you see anything on the screen, such as snow, or is it completely black? If the signal is OK and the TV has no picture at all, the red LED on the front of the set should be flashing a certain number of times. If the LED is flashing, the computer has detected a problem in the set and shut the picture off. If this is the case, there is no way for you to bring the picture back by pressing buttons. The number of times the LED flashes is the computer's way of displaying exactly why there is no picture. The set should then be serviced by a qualified tech familiar with Sony TV's. If the LED is not flashing and the menu comes up on screen, check your signal source. If you are using a cable or satellite box, that box could be bad, and if you are using RCA jacks, the yellow (video) wire could be bad or pulled out.
