Question about Televison & Video

1 Answer

MY 3 year old Samsung LCD TV will not turn on properly. Using either remote or button on TV, the turn on operation cycles thru (on/off) for about 5 minutes, or at least 8-10 on-off cycles before picture/audio comes up. This condition does not occur once TV is "warmed up" suggestions please?

Hi.

The TV works only when it is warm and keep restarting at cold because there is a faulty component.

Such components as capacitors are often used to keep a certain voltage and amp and warranty stability on a circuit. They act as reservoirs wirth a dam that can keep a river swallow, or that can release charge when needed.

One of those is cold, and the TV is restarting because there is a fault condition.
When the TV has "warmed up" and all other capacitors are fully charged, the faulty onw will not be of vital importance anymore and the TV will start.

If the fault is not repaired this can cause more damage to components and circuits after some time.

The symptoms descripted apply to different faults, without testing the TV is impossible to know what problem it can be.

The most common is probably a faulty PSU board.
Often it is possible to see at a glance if one of the capacitors on power board is bulged or leaky.
The power board supplies different voltages. It must be tested at component level to find out if any component is defective.

The inverter is the high voltage board that supplies power to the back light system.
This board is tested checking continuity on a main resistor, reading voltages and testing the AC circuit with an oscilloscope.
If there is backlight , then it is unlikely the inverter.

The digital controller board is the main board inside the TV, this may also be responsible. Main testmust be done by a technician , and consists in reading voltages from PSU to main controller.

In your case it is probably PSU, but parts must be tested before replacement.

The colours on my tv screen are all green and distorted can you tell me what the problem is its a samsung and its only 2 years old


YOU MAY HAVE CONNECTED THE RECEIVER TO AN INPUT ON THE TV THAT IS INCORRECT FOR THE SIGNAL OUTPUT FROM THE RECEIVER.

GET YOUR TV BACK ON THE CORRECT INPUT OR CHANNEL...CYCLE YOUR TV THROUGH ITS INPUTS BY...PRESSING THE INPUT, SOURCE, OR TV/VIDEO BUTTON ON YOUR TV REMOTE OR THE TV ITSELF.

IF THE PICTURE IS NOT RESTORED, CHANGE YOU TV TO CHANNEL 3 OR 4 USING TV REMOTE OR THE TV ITSELF.

IF THIS IS A 2ND TV, TUNE YOUR TV TO CHANNEL 60-73 USING THE BUTTONS ON YOUR TV REMOTE OR THE TV ITSELF.

ONCE YOUR TV PICTURE IS RESTORED, PRESS AND RELEASE THE SAT MODE BUTTON ON YOUR REMOTE TO ENSURE YOU'RE IN THE PROPER MODE FOR CONTROLLING YOUR RECEIVER.

YOU CAN ACCESS YOUR FEATURES, SETTINGS ETC, ON YOUR MENU BUTTON ON YOUR TV REMOTE.

HOPE THIS HELPS!

You have a problem on your Power supply board, possibly a bad capacitor or loose connection. You can look hard at your power board and check for these things or replace it from places like shopjimmy.com or discount-merchant.com etc

Switch TV on then a blank red screen appear then a green and then a blue which then just repeats that sequence of colours every second. The remote control packed up working some month before. - 2 year old...


turn TV on, let the Tv cycle through the three colours, then using the remote press the menu button followed by the standby button. press standby button again and it all comes up working.
