Question about Televison & Video

1 Answer

Television will not turn on consistently

We have a Toshiba TV (let me know if you need the model # - it's only about 6 yr old). Every once in a while it will not turn on unless you unplug the set, wait about 5 seconds, and then plug it back in. We've had a repairman out to look at it, but he couldn't figure out why this occurs. This has been going on now for about 3 yr. We have resorted to plugging the TV into a power strip which we turn on & off in place of unplugging the TV. Have you heard of something like this before & if so, is it fixable?

There are far better experts from this site who would know more if you can post back specific model no or preferably the Chassis no. of your Toshiba.

Just to start the ball rolling, to my knowledge, most models of CTVs since a few years back uses an internal mini computer. Like any computer it does need to be reset and in your case, unplugging (actually for a few hours) performs a hard reset . For a few minutes is a soft reset.

At times, the standby led or power led would also flash a certain sequence to indicate if there is an internal fault detected by the protection circuitry. By unplugging, you did a reset on the protection circuitry and if your problem is intermittent or develops over a period of viewing time (chances are heat related problem), then the protect will auto activate and will not allow power on the next time (if the unit is plug).

Hope that this be of some initial help/idea. Please post back and I'm sure others would be offering detailed assistance thereafter.

Good luck and kind regards.

I have a 6 yr old Panasonic PT 50 LC13 and I need to know how th reset the lamp. i just replaced the bulb and i cannot get the tv to turn in

To reset the lamp follow the steps below.

Press and hold "Volume down(-)" at the front panel and "TV/Video" on the remote control for more thatn 5 secs in power off condition to activate the Service mode map. You can now reset the lamp.

After that check if the symptoms still there. If yes, let me know the status of the led light(Power, Temp, Lamp) and its color to determine where the fault came from.

Infrared sensor won't work in a Toshiba TV

The remote wouldn't work on my brand new 46" Toshiba TV. Comcast person said the tv gave off an infrared signal that interferred with the Comcast remote.

Solution was to turn on cable box FIRST, then TV ( now I use All On button, which turns on cable first). If I turn on TV first, the remote wouldn't work consistently. Hope this works for you.

Screen dark,wont stay on. 52hm95

Here's the online manual for your TV:

Read the section about the red/green lights in front. It sounds like the lamp went out. Mine consistently goes out once every year to year and a half. If you plan on keeping the television, purchase two bulbs, so you have one on hand in case your new one goes out.

Good luck.

My 6 to 7 yr old television suddenly went dead

There is a board that manages the power going into your tv I would check around with local mom and pop tv reapir shops. The board is not expensive its the labor I am not sure where you live but I am sure there are local techs that work on flat panel tv's. They are pretty affordable these days. Most flat panel tv's are rated for 60,000 hrs as there life span. Hope that helps

How to replace front protective screen..

in order to replace this piece, you will need to take the entire case off of the TV, undo all of the wiring inside, and behind the tube.  Once you have the old piece out, yuo need to put the new one in, be very careful, as a sligt jar could ruin it.  Also be careful to get the wiring right as a wrong cable could ruin not only the new screen you just put in but, ruin the rest of the television.
