Westinghousenbsk-730s tv went off while watching. was not changing channel or using remote at all when just turned off. power indicator light is on so its getting power. black screen and no audio.

You won't be able to see the light from remote's LED (Light Emitting Diode) because it is IR (Infra Red) which is invisible to the human eye.

Try re-entering the code for your tv to see if it works.

If that doesn't work, the remote might have just died. It happens.

Get yourself a new UNIVERSAL REMOTE for less than $20 and just program it for your tv.

Good luck and post back to let us know how it works out.

Try this as most remote controls work the same when manual setting.
Here you go. This will work with most all universal remote controls. If you don't have the code do the following:
Automatic Programming
With automatic programming, the remote control tests all the codes available on the Code List and assigns the correct code for the selected device. Although this method can be more time-consuming, it eliminates the need to look up codes and enter them manually.

1. Turn off the device with which you want to use the remote control.

2. Press and hold the corresponding button on the remote control
(TV, VCR, SAT, DVD, CAB or AUD) until POWER INDICATOR illuminates. It should take a couple of seconds for the light to remain solid. The remote control is in programming mode.

3. Press and release power button. The POWER INDICATOR flashes once and stays on indicating the unit is in Power Scan mode.

4. Press CHANNEL up or CHANNEL down repeatedly until the device turns on.

5. When the device turns on, press OK to store the code.

Note:
• To exit without storing the code, press BACK.
• T he unit will search for the next code or the previous code if you press
CHANNEL up or CHANNEL down after the device turns on. (go slow you need to press OK when the TV turns on) if you mess up turn TV off and start over.
6. Press any other button. If the device responds, the remote control has been programmed. If the device does not respond, repeat steps 2-5.

Any universal remote will work. Just look on the back of it to make sure it supports your brand. That's the key. Just follow the directions for manual input. It will work something like this.

Try changing the channels on the VCR itself. If you can do that, then it would indicate a problem with the VCR's remote. If you are still unable to change channels on the VCR manually, it could indicate a circuitry problem, for which you will have to get the VCR serviced.

1. Make sure the device you are programming is turned off.
2. Press and hold CODE SEARCH.
3. Press and release TV, VCR, or CABLE corresponding to the device to be controlled. The indicator light will flash once to indicate the search is enabled.
4. Release CODESEARCH.
5. Press OFF/ON repeatedly until the device turns on.
6. Press CHANNEL V (channel down) for verification. DO NOT press any other buttons at this time.

If the channel changes on the device, the code is valid. Press ENTER to complete the search.

If the channel does not change, turn off the device (without attempting to use the remote). Then continue search by repeating steps 5-6. When all codes have been searched, the indicator light will flash twice and the remote will return to the normal mode.

Ok there is no light on front panel. doesnt blink or try to turn on? this is an indication of a main power interuption. as always the main fuse can be checked.

i have the exact same issue.
have you found the cause?

I went to add/delete channels in my menu on my symphonic and it let me scroll through the channels, make sure you have them all set to add (by pushing the volume buttons to make them light blue instead of purple)....after adding all of your channels (or just the one if you use dish) just power the tv off while on a channel and then power back on and you should have tv.

The keyboard switches are going bad part# 432P109010 (there are ten of them).To verify this, disconnect the connecting wire to the keyboard pc board and see if you still have the problem- the remote will still function normal- the green power led will not light up when you power on the TV with it disconnected so listen for the click and wait for the TV to power up when you use the remote.

same frustrating symptoms on brand new 42inch here! tv just turns itself off sometimes without warning or if changing to certain channels. leaves red light flashing for a while then red light goes away. any attempts with remote gives flashing green liht on tv. manual power off and on restarts tv but auto off again. found while manual power on keep changing channel on remote till stable picture appears. then use remote to shut down tv - solid red light indicates standby mode. then use remote to turn on again... till next time it happens. but what is technical fault??
