The TV keeps turning itself off by itself. The cable remains on all the time. The appliance store brought me a new one, and it does the same thing. A repair technician replaced 2 boards in the back,and still turns off by itself. What is the problem?

F1 on this unit means that the door latch and or the controller has failed.... you sometimes can turn the breaker off to unit and turn back on and it willl reset... most likely though it will require replaceing the control board... these units get so hot on self clean and as a servicer it is what keeps us busy.... f1 can mean three things a bad door latch mechanism, bad control board or the ribbon cable on the touch pad itself has failed and requires replacement of the touch pad... most of the time it ends up being the control itself and some of these models when you order the control it comes with a new door latch mechanism... turn power off and try that first if no cure then order parts from appliance repair or a reputable online store like

Hi! The codes of your remote control for Toshiba TV are 1011, 1017, 1018, 1042, 1054, 1090, 1091, 1094, 1097, 1100, 1103, 1107, 1110, 1122, 1191, 1192, 1209, 1214, 1265, 1266, 1279, 1290, 1294, 1300, 1305, 1306, 1311, 1314, 1323, 1344, 1346, 1353, 1369, 1381. If in case none of these works you can try doing manual search and these are the steps.

1. Manually turn on the TV.
2. Press and hold the TV key. The LED turns on and remains on. Keep holding down the TV key.
3. While holding the TV key down, press and hold the POWER key. The LED turns off. After holding down both keys for three seconds, the LED turns back on.
4. Release both keys. The LED remains on.

Throughout the programming of each key, be sure to keep the remote pointed at the IR sensor of the TV you are currently programming the remote to control.

5. Press and release the POWER key repeatedly until your TV turns off. Each time you press the POWER key, the LED blinks, and the next code in the list is sent. This process continues until all of the codes in the Code Lists have been tried. If your component turns off, you have
found the correct code. (If it cycles through and the LED blinks four times and turns off, all codes have been searched. The Manual Code Search method is exited.)

Because there are so many codes, you may have to press the POWER key many times—possibly hundreds of times.

6. Once you have found the correct code, you must save the new code by pressing and releasing the STOP key. The LED turns off. You must press the STOP key to save the code or the correct code will not be stored! When you press the STOP key, the code is stored.

1. 1. Manually turn on the component you want the remote to control (TV, VCR, DVD, DVR, satellite receiver, or cable box).
2. Press and hold the component key (TV, SAT•CBL, DVD•VCR, DVR•AUX) you wish to program. The LED turns on and remains on. Keep holding down the component key.
3. While holding the component key down, press and hold the POWER key. The LED turns off. After holding down both keys for three seconds, the LED turns back on.
4. Release both keys. The LED remains on.
5. Press and release the POWER key repeatedly until your component turns off. Each time you press the POWER key, the LED blinks, and the next code in the list is sent. This process continues until all of the codes in the Code Lists have been tried. If your component turns off, you have found the correct code. (If it cycles through and the LED blinks four times and turns off, all codes have been searched. The Manual Code Search method is exited.)
6. Once you have found the correct code, you must save the new code by pressing and releasing the STOP key. The LED turns off. You must press the STOP key to save the code or the correct code will not be stored! When you press the STOP key, the code is stored.

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.

I would replace or at least resolder the connections on the cable jack on the tv itself. You seem to have a loose ground or cold solder joint on the ground portion of the jack. Be sure as well to check that your actual cable has a good solid end on it as well.

Hi,

More often than not, the humming sound on any electronic device is brought about by the AC side of the power supply not only of the device itself but also all other equipment it is attached to. In your particular case, it maybe introduced into the system from:

• (coaxial) cable TV leadin;
• connections of DVD, VCR, game consoles and others;
• electrical noise from lamp dimmers, lights with electronic ballasts, wireless phones.

It is interesting to note, that the noise could be from other appliances plug in the same circuit as the TV, you of course could try plugging it into another outlet or branch. In some instances, you could even try filtered regulators similar to those used by desktop computers.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

If you're connected to a digital cable box, I would try using the external component connections and bypass the TV's tuner. If all you have is straight cable coming into the house, it could be the cable signal itself or a defective tuner in the TV assuming all the menu settings are correct in the TV.
