I was told by the repair service to unplug the power cord for about 5min. This resets the internal computer. I think this helps but does not cure the cause. Good luck.

SOURCE: panasonic plasma th-42px25 turns itself

The condition of your TV called power supply overcurrent shutdown. The TV is going into a protection mode to prevent further circuit damage. That's why it will not turn on or not powering up. I would concentrate on the power supply section board. Bad regulation of the incoming voltage could caused this issue although,there is a capacitor across the incoming line and nuetral.Maybe its leak or dry up and cause the problems,change it out with one of identical rating .I would probably also check the flyback circuit and flyback transformer although now you are getting into dangerous area,especially if you have no electronic experience background. It could be also be a loose ,crack or cold solder joint,a blown fuse,fusible links or other component .It could be one of several boards.Unfortunately the level of sophistication on these TV make it virtually impossible to diagnose them further without taking them apart and probing around with a multimeter and other tools.This TV is handy enough to take to a repair shop find a good one.You will probably have to pay $75 to $100....

Hope this may help you..

SOURCE: Panasonic PT-50DL54J DLP TV Flashing Light

I had the same problems that most of you have been having, tv turning on and off, lights flashing in all different colors, having to unplug tv to reset and all of that good stuff. I noticed that most of the time this would happen once the tv would start to heat up, and I could hear the fan working a little harder. Well I am not an electrician but It was very simple to unscrew the lower bottom park of the tv, where the fan and most of the electronics sit, then I used an oxygen tank ( I work for a medical company ) to blow out all the dust in the tv, ( you can olso use the compressed air use for computer, but if grandma or grampa have some O2 laying around, it works really good, LOL. )and was very surpriced to see how dusty it was, then I removed the MAIN FAN ( you only need to remove three screws, however there's a box in fron of it, which you'll have to remove first in order to get to the fan ). this may sound a little complicated, but trust me it is not, once you have taken the fan off, clean it all the way around ( best to use a clean rag, the compressed air was not doing the job.
long story short, once I cleaned the fan and put it all back together. The TV still didn't work LOL, Just kidding, It has been working perfect for a little over a week.
If I can help in any other way, please e-mail me @ gsierra11@yahoo.com

hope this helps.

Hi i have panasonic Veira model TH-42PX70A my tv has stopped working i have no sound and no picture. when turn on the standby button flashes red. If try to turn on from standby mode the green light appears...


Hello this may be a power supply problem, but my professional guess is that your Y-Substain board has failed. Count the number of times the red light flashes, this indicates the reason of failure of the unit. After which check ur user manual for troubleshooting section, your manual may give you a listing of the number of blinks and what they mean. If you want take off the back and check the fuses on the power supply if one is blown then replace the power supply as just replacing the fuse will just blow it again. If no fuse are blown then have a technician replace teh Y_Substain Board.

The Power Light is Red


yeah, should stay red when unit is turned off, indicating there's power but it's doing nothing.

Per user manual:
Solid red - power off (standby mode)
blinking red - power off (now cooling)
blinking green - power on (preparing to light lamp)
solid green - power on

Thomson DTI6300-16 digital TV recorder frozen, red light on constantly, no resposnse to any commands. I think it needs a factory reset - how do I do this?


Try Resetting the box to its factory setting:
  • Menu > Setup > Help
  • Then press the Green Button (Even though it doesn't show as an option)
  • Then press the Red button for a full reset
Warning: You will lose all data on the Hard Disk!

I did this when mine wouldn't record anything and dumped all my pre-recorded programs.
Worked a treat.

SONY GRAND WEGA


I have a KDF60XS955. When I power it on, the fan comes on, the standby light flashes green several times, the lamp comes on and the standby light goes to solid green. This lasts for less than 5 seconds then the lamp goes out, followed by ~30 green standby flashes, the lamp coming on with the solid green standby light for about 5 seconds then shuts off the lamp again. I can hear/feel the fan running the enitre time. This cycle continues endlessly. Please help!

Thomson dti 6300 freeview box will not come on just shows constant red/orange light flashing all the time, tried leaving power off etc....anyone know?


What to do: if you have a solid amber light If the power light on the box will not change from solid Amber to solid Red then it is possible that a problem has occurred with the current in use software. Before attempting a fix, power the box off and on at the power socket and then wait at least 5 minutes for the solid RED lamp to appear.
If it still remains solid Amber and the box will not come out of standby to ON (Green light) then this can be corrected using the software revert procedure which is done using the box front panel buttons as follows:

1. Remove power to the unit by removing the power cable from the back of the box.

2. Wait 20 seconds and then restore the power cable while pressing the standby button repeatedly on the front panel of the box.

3. Release the standby button immediately when you see a lamp flash on the box's front display, and then immediately press the following front panel arrow buttons in this sequence:

- Menu
- OK

Note: you have to do this quickly and in sequence

4.The Orange light will flash and the STB will then reboot and should return with the previous version of software.

5. The box will now be running with the previous software version but it will automatically update with the latest version within approx 2 hours and you will be notified by message which will appear in the Message area within the Main Menu.

If you're still having problems please call 08444 159 159 and a member of the Technical Team will be happy to help.

Sony LCD turns off 34 flash turn on 30sec repeats ...


The self-diagnostic function of the projection television 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, some of which you may be able to resolve without the need for service.
  • If the STANDBY light flashes three times in sequence, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
  • If the STANDBY light flashes four times in sequence, the television may be overheating. To resolve this issue, ensure that the back of the television is well ventilated.
NOTE: If the television will not turn on immediately after being turned off, wait for the fan to finish its cycle, then attempt to turn it on again. This is part of the cooling process of some projection televisions and is normal operation.
If the flash sequence is not listed above, or the light continues to flash after troubleshooting the indicated issue, follow the steps below to perform a power reset on the television:

  1. Turn off the television. IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
  2. Unplug the television power cord from the electrical outlet.
  3. Let the television remain without power for 60 seconds.
  4. Plug the power cord back into the electrical outlet. NOTE: 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.
  5. Turn on the television.

If the issue is still unresolved after following all of the troubleshooting steps, service may be required. Please note the number of times the STANDBY light flashes and relay that information to the service center.
