'95 Toshiba CF32E50 TV turns off by itself

This has always been a reliable set. Started to turn itself off. Next, after unplugging it and letting it rest a moment, it will turn on again, only to shut itself off.

Toshiba tv 40rv525u has started to change channels


My TV 40RV525U changing channels, menus itself for few months ( I use antenna).
my son tried to stop the channel scrolling by enter weird number into the channel to stop it scrolling such as 555, 777..
later, it turn on off by itself and unable to hold on a channel
I call Toshiba customer service and they ask money $25 for troubleshooting but I denied since I do not want to waste money and time.

Now, I found how to fix it myself.

In my case, something was wrong with the signal comes from the button control on the left side of the TV.
========================
What I did
========================
unplug the power cord.
Remove back cover.
Look into the motherboard ( biggest green at the center).

First, I disconnect a connector on the motherboard come from the IR board that receive the wireless signal control ( meaning the remote is disable).
I turn on the TV, press on Menu button on the TV side. Menu is still scrolling.

I turn off TV, disconnect power cord and connect the IR connector back to the motherboard.
I then disconnect the nearby connector that comes from the side control buttons.

Turn on the TV by remote, press menu button on the remote to check. The menu stays.

DONE.

I use electric tape to seal off the connector and let it hanging there.
Close the TV back panel

I have been watching TV for 3 nights without menus/channels scrolling.
NO AVAILABLE red message when watching DVD is no longer existed.

Hope this help someone else.

Toshiba 27DF46 27" TV started only turning on


Bad solder connections on an older TV is common. Check all your solder grounds on anything mounted on heatsinks. The other thing is bad capacitors. Always suspect the 160 volt to 250 volt at 1 MF, 2.2Mf or 4.7Mf for being bad. This is true for many repairs for any brand of TV.

Toshiba 46H84 tv turned off light blinking


The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

Will not turn on


I have an Olevia screen that sometimes does this. The solution is highly technical. Try unplugging the unit, wait a couple of seconds, and then plug it in again. I don't know what's going on, but this always works for me.

Toshiba TV turns itself off


I unscrewed the back of the CRT and vacuumed off the components (tv unplugged of course, and wait a while for capacitors to loose their charge). This seemed to fix the problem. In addition to that, it got rid of the faint red hourglass lines that I had noticed when the screen was supposed to be black.

So far you have done all you can and you have done everything right. The fact that the TV turned off by itself and then turned back on by itself suggests that one or more solder joints have come loose inside the set. A qualified tech should find this easy to fix, and Sony sets are always worth repairing, so it is now time to have the set serviced by a tech experienced in Sony standard sets.

Power light flashing/ no picture


I have the same problem. The only way to get the TV to come on is to unplug it, but once you get it back on it turns itself off again in a few minutes.
