Question about Samsung Televison & Video

1 Answer

Wont power on

When the tv is plugged in it makes a really high pitch whistle noise, don't know if the power supply is dead. I think it might have been zapped in the last big lightning storm.

SOURCE: High Pitch Noise on 42" PLasma Gateway TV

how old is your plasma TV? try check the switch / volume of the sound settings.. Sometimes, when you always increase the volume, it will tend to alter the limit of sound and causing the sound to provide sound undesiredness. I suggest to check it with a liscensed technician.

SOURCE: High pitch noise coming from the tv.

I suspect you have a bad set of capacitors in the control module. This problem usually starts out as a high pitched noise but can lead to the TV not turning on. Please see the link below, posted by StivO. It gives step by step instructions on how to replace the capacitors. This is a very inexpensive fix.

SOURCE: TV won't come on, it just stays in standby mode

Hi.

The TV staying in standby and the light flashing indicates that the TV is in fault mode (often called protect mode). This happens when an internal fault is detected, and the main board set the unit in forced stand-by with the led color changing.

Before doing anything else try disconnecting TV from power for ten minutes. Restart the TV with no device connected, leave it on for a while and see how it goes. Test the TV with different devices (eg. DVD, VHS,sat box, console etc .)

In your case it looks like there is no clear indication toward a particular fault. The TV coming on at random times, may point at a defective PSU, but other failures such as defective main board, overheating, defective inverter, or faulty Timing controller (TCon) may result in the same problem.

The most common fault that may cause the symptom you described is PSU. Unless there is clear sign that the PSU is damaged, this is still far from being enough to decide that PSU is the culprit. The power supply must be tested before replacing parts. Testing is done reading PSU out on different voltages. This is an operation that must be done by a trained repairer.

The high pitched noise may be given by a defective PSU capacitor. In that case the bulged or leaking capacitor is usually easy to spot looking directly at the PSU.

To book a repair call the manufacturer at the number listed on the owners manual.

TAKE THE AC ADAPTER APART. LOOK AT WHERE THE MANUFACTURER PUT HIS GLUE AND REDO IT CLEAR NIAL POLISH WORKS BETTER IT FLOWS UNDER THE PARTS BETTER. YOU CAN PLUG IT ALL IN WHEN ITS APART BUT MAKE SURE NOTHING CAN SHORT OUT. THIS WAY YOU CAN PINPOINT WHERE THE NOISE IS COMING FROM. OTHERWISE GLUE THE TRANSFORMER AND ANY SMALL FERRITE BEADS THESE SWITCHED MODE POWER SUPPLIES OPERATE AT HIGH FREQUENCIES AND LOOS PARTS CAN VIBRATE CAUSING THIS NOISE.

High pitch sound coming from circuit board, cannot


First, you will want to isolate the problem. Is it feedback from an AC outlet you have it plugged into? Is it a recent noise that just started with no changes to Tv or its environment, then you may want to consider that a circuit is going and decide if it is worth repairing, You should find that type of fix at a shop for under $100

Television won't power up


It sounds like the high voltage circuit got damp and arced. This arc caused the horizontal output transistor to short.
You might try replacing the output transistor if you're experienced in this type of repair. If not then you need to take it to a repair shop.
The "whistle " you're hearing is the power supply indicating that it has a short on its load. When the power supply has an over load (short) its frequency drops down when your ear can hear it oscillating. This type of power supply is a switching power supply normally operating a several thousand hz(cycles) which is out of range of human hearing.

TV screen wont turn on but just a loud noise coming from the tv


I think maybe the G-board needs to be replaced. A TV shop will have to repair it. They normally start around $200.00
