Question about Projection Televisions

I have a sharp LCD TV model LC-52D64U that does not power up. When I plug it to the wall outlet, both the power indicator light and the opr light on the front of the unit flash three times and shuts down. What is the cause of the problem and how can I fix it ? Thank you.

    Thank you for your reply.
    Would it be easier to replace the whole power supply unit since I could do it myself?

  • norrep May 05, 2008

    Dear Pagebor, I have replaced the power supply unit and the same problem is still there. I also observed that when I plug the TV to the AC outlet, a relay on the power supply board clikcs and a small red LED near IC 2008 on the main board flashes. I hope this helps you in any way to find the problem.

    Thanks again !

    I have replaced the power supply unit and the problem is still there. Also when I power up the TV, two small red LEDs on the main board flashes, one near the main CPU, and one near IC 2008. Hope this helps you in any way.
    Thanks again.

Panasonic tv model number pt-61LCZ70....green light blinks when cut on but no picture or sound...all u hear is the fan on..


Try disconnecting all of your HDMI cables and plugging the power cord of the TV into another wall outlet. If this resolves the issue, you may have had a small power surge from either your wall outlet or one of your source devices. It is recommended to connect your TV to a surge protector if you haven't done so already.

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).

Flashing red lamp light on front of my sony tv model # kdsr60bxr1/ no picture , no sound


Hi,
The Standby/Power light of the TV blinks when there is any internal malfunction in the TV. The self-diagnostic function of the TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue.
Few examples are given below; some of the issues may be resolved without the need for service.
1 blink / 2 blinks / 5 blinks: - This indicates that there may be a power-related problem with your set.
3 blinks: - This indicates that there may be a power-related problem with your set. The set will need to be serviced to allow a technician to determine the specific issue that needs to be repaired. If the power light flashes three times in sequence in a Lamp TV, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
4 blinks: - This indicates that there may be a back light or lamp power problem.
6 blinks: - This indicates that there is some kind of audio problem with your set.
7 blinks: - This indicates that there is a temperature problem with your set. Please check to make sure that the air vents on the sides and back of the set are not blocked or clogged and there is adequate ventilation around the television. We recommend that you check and clean the vents periodically to make sure the set receives adequate air flow. If the problem continues, the set will need to be serviced.
8 blinks: - This indicates that there may be a video-related problem with your set. If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset:
Try the following steps to check if the issue can be resolved.
Turn off the television.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.

If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
If the issue continues to occur, service may be required.

Thanks for using Fixya.

My Sony Grand WEGA LCD rear projection 51" turns itself OFF every 20 sek and turns itself back ON after every 35 sek. ???


Try resetting the TV to the factory settings. 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.

I have a Sharp flat panel model LC-20SH4U. The units power LED light is red. No effect (sound or picture) when remote or on/off switch is activated. The LED light slightly blinks.


Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

NOTE:
Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.

1. Unplug the TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.

Hope this may help;

LC-32SB24U (sharp lcd tv) remote control just stopped working. Yes, I checked the batteries and replaced them. I'm wondering if the Remote Control Sensor light should be on the TV? There is no light...


I actually was having the same problem and just fixed this. I just unplugged the tv from the back for about a minute and then plugged it back in and it worked fine, so give that a try.
