Sceptre tv won't turn on after power outage


You may have to open it to see if the line fuse that the power cord goes to is good or bad.

We have a rear projection tv that has no sound or picture after a power outage??


Suggest unplugging for 15-30 min to allow capacitors inside to discharge and reset and systems from the outage. Then plug in and see. It could be the power supply or a burned out bulb from the quick pulse of loss of power also.

VCR will not show picture or menu on TV after power outage.


Hate to say this, but when power outages occur, things like vcr's are the first thing to fry. But if you feel that the vcr is fine as far as powering up, then unplug it from the wall socket for 30 minutes or so, plug back in and see results.

When TV is off and there is a power outage the TV


This TV has a Power Standby feature (pg. 40 of your manual) which allows you to more quickly turn ON the TV. When power is lost and then restored, your TV will display the HP logo screen while it boots the digital circuits. After it is finished, (unless it was previously turned on) it should appear to be OFF. This is normal operation. If you like, you can change this setting to LOW POWER. At this setting, each time you turn on the TV, you will see the HP Logo screen and picture/sound will appear after 20 seconds. Again, take a look at pg. 40 of your owners manual for more information.

I lose the picture after 20 - 25 mins. I turn off the TV and turn it quickly back on and the picture works fine; then 10 - 15 mins goes by and I lose the picture again. I turn the TV off then quickly back...


it probablt needs power supply capacitors, if you can take it apart and inspect the power supply, the bad capacitors usually are expanded and have a bulge at the top, you would need to solder these parts in, so some skill is required.

Had a power outage while watching tv. Then 3 blinking lights.


This is an on-going problem with DLP sets. Normally you shut the set off and the cooling fan cools the lamp down and then it shuts off. In your case, of which it's not your fault, however your lamp has taken a major hit by not properly cooling down, in turn, you need to replace your lamp at this time.
I suggest in the future if you have an electrical storm and a chance of a power outage while your watching tv, I would'nt play that model or any other model of a DLP set.

Tv comes on just the sound about three seconds later tv shuts off


I have the same issue with mine and have a solution that sometimes works. I had a repair guy come to check it out and he powered off the TV so that the red light was no longer blinking, then he unplugged the TV for about 30 seconds or so and then plugged it back in. He then turned on the TV and it worked. He said it would cost about $400 to fix the issue (some circuit or something). I have since expeerienced the on/off problem (due to power outage) and now I cannot get the TV to work. But at least give this solution a try and please post to let me know if it worked or not. Good luck!

Dynex (no database) since power outage


What you have to do it go to the TV Menu and go to channel. Then go to channel scan and do one of those. THe problem is that is just doesnt know where to look for channels, but a quick scan will fix that.
