Take it back to the shop, if it's 3 months old it must be under warranty.

SOURCE: Connecting multiple A/V cables to 1 TV

Hi zantar412,

Yes, there are devices to help you. You should shop for an “RF Modulator.” While the intention of this box is convert an A/V signal to RF for older televisions, many modulators offer multiple inputs which can be chosen with a switch. Be sure to check both the input and output options on the box that you buy to ensure it will be compatible with your components and television.

Thank you,
Jason,
Go Ahead. Use Us.

SOURCE: tv is only 3 months old = tv won't turn on

I suggest returning to supplieras it will be under guarantee and if a third party does any work it will be voided.

The flashing may indicate a failed power supply. Or a bad backlight tube.

Only 3 months old? Any warranty?

Considering its age I would say a defective part or poor assembly is to blame.

How do I fix the problem with my TV? Details are below.


Normally on the Panasonic tv this will call for a service call. The key to getting it repaired correctly is to check for a certified Samsung repair shop because most of the parts come from Samsung. Now if you want to do your own research call to 800 number for Panasonic Tv see if there are any problems with that model that the manufacturer has extended but does not post. I had one repaired that the red light on also so I understand and it went out approximately 4 3/4 years. If your in the Atlanta area use Norman electronics they have repaired hundreds on tvs for me due to my work.

Tv will not power up



Press the TV button or ON/OFF button while remote is in TV mode and there's a source of power to the outlet or outlet strip.

Make sure the TV is plugged in.

You might have tried to turn on the TV during the lamp cool-down. Wait a few moments and the picture will appear.

Has the power light on the front of the TV been blinking for one minute? If so, the lamp may be dead. Refer to the Power indicator
is blinking or flashing section below for more information.

When you first plug your TV into an outlet, the Power indicator on the front panel will light and blink for approximately 30 seconds
and then go off during the initialization of the TV. This happens only when the TV is unplugged and plugged back in. The TV can
only be turned on after the Power indicator goes off.

Check the wall receptacle (or extension cord) to make sure it is "live" by plugging in something else, such as a lamp.

Something might be wrong with your remote control. Press the POWER button on the front of the TV. If the TV turns on, check the
remote control solutions on page 53.

Multiple TV Setup might be set to the wrong option. Press MENU/OK on the front panel. Select Setup Options, then Advanced
Options, then Multiple TV Setup. Choose TV (default).

No power, no nothing


Your problem either lies with the power supply or main board. I suggest you start with the power supply. Make sure you have standby (5vdc) power with the set plugged in. I would also check for any bulged power supply caps. I would also suggest you verify that you have a 110vac outlet in good working order!

Good day!

Please follow this procedure to fix your problem:
  1. Open the cover of your TV.Remove all screws at the back.
  2. Next,power ON the TV and check the output voltage of power supply using voltmeter.
  3. It should have not less than 5vdc for system board,12vdc for sounds and 24vdc for inverter board.If the 3 supplies are got a voltage drop your power supply had problem.For example if you check the 5vdc then the reading is 4.50vdc only.
  4. If you have voltage drop,check some leak/bulge on top capacitor on power supply.replace it by using soldering iron and soldering pump.
  5. When the power supply looks like OK,no voltage drop and no leak/bulge on top capacitor.The problem is your system board or main board.There's no easy remedy for that.You have to replace the whole system board.
I hope this solution helps you to fix your problem.Thank you and good luck.

I purchased a SUPRA 32 LED TV FULL HD Model No SLED32OT9001R from UAE 3 months back and from the last few days TV is not working even the power led at the front pannel doesnt shows power.


Be sure the power cord is plugged in to the a/c outlet fully. Take a table lamp and plug in the same outlet to verify power is good. If no power, check for circuit breaker tripped in main breaker box.
If problem seems to stay with tv, I would contact seller. You should have at least nine months of warranty left.

My kds-r60xbr1 sony wega projection tv is blinking green then red and wont go on how do i fix this problem .i also just replaced the bulb about 3 months ago.


Try connecting the TV directly to a different wall outlet and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue persists, then the TV requires service.
