Please tell me the model no. and make of your tv. Also try turning it off and then turn it on after 10-15min.s. Remember to unplug from the power socket mains.

Start by checking the fuses on the powerboard. for anything else you will need a service manual, brand and model?

Try first unplugging the power cord for ten minutes.

    Try first unplugging the power cord for ten minutes, this often can solve the problem of devices not starting after a power surge.

    If the TV does not restart after leaving the set unplugged for a while, then the power surge had damaged the power board inside the TV.

    If the TV is under warranty, then ring the phone number listed on the owner manual to have the repair covered.

    If warranty is expaired, the most common situation is that aftee a storm or a power surge one of the capacitor on TV power board has blown.

    In this case the best thing to do is having the faulty capacitor replaced by a local technician.

    Try first leeaving TV unplugged for ten minutes up to three hours, often that can fix the problem.

No power output or display.green standby light flashes.


Sounds like either a blown mainpower fuse or the thermal fuse for the power transformer. If the protect circuit was kicking in, the display would light up, but then turn off with a red blinking light. the green light with no display means the transformer is not getting power.

Hi,

The most common cause of Panasonic Rear Projection LCD TVs not starting is bulb failure. The PT-60LC13 users manual gives some help in translating the LEDs on the front of the TV.

If the TV worked normally for a period of time (months or years) and won't start, the most likely cause is bulb failure. There is no way to measure the bulb, sometimes the bulb is visibly damaged when it fails. Remove the Lamp Assembly and look at the bulb.

If there was an On-Screen Lamp Replace warning and TV won't start, bulb has failed.

The first step with all Panasonic Rear Projection TV "No Picture" problems is bulb replacement. If that does not remedy the problem, get a technician, there are no user serviceable parts. Guessing if the ballast, power supply, controller board or optical engine is faulty is not practical.

The Panasonic Lamp Gallery shows all Panasonic models and Lamp Numbers. There is also a link to Panasonic DIY bulb and lamp replacement.

I have a Mitsubishi WD-62525 HDTV that suddenly wont turn on. Just has a green blinking light when you hit the power button. Any ideas?


I found this on another website, most likely it is your power supply capacitors.
  1. Press the "reset" button and hold for 10 seconds .... Does TV turn on and blinking green light turn to solid green.

  2. Unplug the TV from it's power source for various times, ranging between 5 minutes and 24 hours..... Does blinking green light continue upon plugging in the TV.

  3. Disconnect ALL devices from the TV; DVD, Tuner, Cable Box, unplug the TV for various duration times .... Does blinking green light continues upon plugging in the TV.

  4. Press Power and Menu buttons simultaneously and hold depressed for 20 seconds .... Does blinking green light continue to flash.

  5. Press Power and Display buttons simultaneously and hold depressed for 20 seconds .... Does blinking green light continue to flash.

  6. Insure that no front panel buttons are inadvertently stuck in an "engaged" position.

Diagnosis: If none of the above test resolve the issue, then the failure lies in one of the following:

  1. DM Module Capacitors have FAILED.
  2. DM Module is defective.
  3. EEPROM Board failure
  4. Power Supply failure.

That can be caused byy many different things, but some of the likely causes are a power supply failure, or if it's a plasma TV, the sus boards or even the scan out boards may ave failed. That's one that you will need to have an experienced technician look at.

My tv does not turn on


Hi,

This problem is likely a failed power supply. This is a known issue with this model TV. It will normally occur soon after the warrenty expires. It can also be caused by a voltage surge produced by a power failure. You might wish to unplug the TV for an hour or more. If this power reset does not allow the TV to turn on component failure is indicated. These sets are assembled using the wave soldering process they are known for having cold solder connections. The safety circuitry shuts the TV set down or will keep it from turning on when it detects a problem. This model of TV has over 2,000 parts, which includes millions of transistors inside the integrated circuits. The capacitors will change value, leak and become defective. Resistors will change value and burn. Diodes and IC can go bad. This may have a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again if the parts that caused the failure to begin with are not replaced. The only way to know for sure which parts that are no longer within factory specs and for a proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment specifically designed for TV service and the skills to use the test equipment. I wish I could tell you there was a quick fix or button to push that would fix the TV but that is not the case or the solution needed to get the TV operating correctly.

Let me know, if need further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

When I turn my tv on I only have a flashing red and green light. The power to the tv does not come on.


Most failures when the TV does not power ON, are related to the power supply and some cases to the main board. If you intend to fix the TV yourself is easy by swapping boards or if you are able to isolate the failure to one particular board(power suppy) even better. If you're DIY, open the tv and check the power from the power supply to the main board using a voltmeter. You should be getting 5, 12 and 24 volts going to the main board.
If you need further assistance. let me know or write to jah2mil@hotmail.com

the status light blinking red means a fan (the unit hs 4 of them) has failed. you need to determine which one. use the self diagnostic function:
Error Code Operational Check
Note:
The TV must be in “Shut Down” and not manually switched Off, to perform the Error Code Operational
Check. When the TV is switched Off, the code automatically resets to “12” No Error.
Press the front panel “DEVICE” and “MENU” buttons at the same time, and hold for 5 seconds to
activate the Error Code Operational Check. The LED will then flash denoting a two digit Code.
Note: The front panel buttons must be used, NOT those on the Remote Control.
• The number of flashes indicates the value of the MSD (tens digit) of the Error Code.
• The flashing then pauses for approximately 1/2 second.
• The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.
Example: If the Error Code is “32”, the LED will flash three times, pause, and then flash two times.
• The Error Code is repeated a total of 5 times.


and read the code.
35= Chassis Fan failure
36 =Exhaust (Back Cover) or Lamp Ballast Fan failure
37= Engine (DMD or Lamp) Fan failure
