SOURCE: TV will not turn on to channel 4 everytime. I have a cable box and need the tv to remain on channel 4.

As long as the tv is not unplugged it should stay on the same channel when turned back on. If you have the tv plugged into the cable box, when the box is shut off it basically unplugs your tv and the tvs memory is reset. The tv should be plugged in to its own outlet or leave the cable box on and turn off the tv. If you turn everything on, cable box and tv, and have a picture, go into the tv menu and auto program the channels, it should only lock in on channel 4 since it will be the only channel the tv will receive.

It sounds like you may have blown caps on your power board. This is quite common with LCDs. Though it could truely be a number of other things. Best thing to do is take it to a repair shop if you arent electronic savvy. If you feel comfortable taking it apart look for circular caps that are bulged on your power board.[the one that the power plugs into or immediantly runs to...usually brown] IF this is not your issue you may have a short somewhere.

Please take a moment to rate :] Thanks!

Mitsubishi wd-73738 turns itself back on


Hi,

It sound like the remote is powering off the cable box but not the TV. The remote control may need to be reprogrammed to the TV. When you press power it may only power off the Cable box. At that point, try pressing the TV button on your remote and then Power. If it does not power off the tV after pressing the tV button, the remote may need to be reprogrammed to the tv. Cable companies usually have the codes needed to program their remotes to the TVs.

My tv shuts itself off!


Quite a long "description". "How can I fix it without having to check the back of the TV or going to a repairman?" (I altered the spelling etc a little there.)

Answer: Go to the internet and search for "Magic TV Repair Wand" and let me know if you find one---

Power light keeps flashing and won't turn on/


Hi,


If only power button is blinking then there is a problem only in your power button tube.

This sounds like a problem with the reset in the TV. This is not a reset circuit like you are thinking. It has to do with the micro and relay circuit in the TV. Another way around it would be if you had a cable box. You could hook it up to the cable box and just shut off the box and this would turn off the TV.

Also Unplug the TV and wait for a few minutes....plug back in. Hopefully it'll reset itself. If not, try reprogramming the remote and use that making sure there are good batteries in it.

If nothing works pull the back off and look around for a fuse near where the power cord is connected. It may be a circuit breaker too. Locate but DON'T TOUCH the large black wire going into the side of the tube. Follow it back to the fly back transformer or voltage Tripler. Look for a fuse here on the circuit board. Reason I say don't touch the wire is that it could be charged at about 28,000 volts which is normal for a colour TV. The TV glass and the outer coating forms a capacitor which stores DC current. An open fuse would mean the power supply is not functioning.


Please get back to us if you have any further query or else accept the solution.

Thanks for contacting fixya.com

The cable guy programmed the cable remote to turn on/off the TV. We used it to turn the TV to stand-by. Then pushed the power button on the TV to turn the power off. Haven't been able to turn the TV on...


First use the original remote control that came with your tv, or just manually turn it on at the tv itself to bes sure it is working. If it works you should call the tech support for the cable company to program their remote control to a different code - or put it back to to factory state and just use two remotes.

Change the batteries on the remote, point the remote at the Sony, and hold in the power button for 5-7 seconds. Then depress and re-press the power button - see if you can get the tv remote to respond again.

Then, always try the quick reset:
How to perform a power reset on a Sony® television.
  1. Turn off the television. IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
  2. Unplug the television power cord from the electrical outlet.
  3. Let the television remain without power for 60 seconds.
  4. Plug the power cord back into the electrical outlet. NOTE: If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
  5. Turn on the television.

Westinghouse LTV-32w4 HDC - adjustment buttons unresponsive, volume drop, etc.


plug your cable connection to a vcr "in" then run a seperate cable cord from the vcr "out" to your television (which should be on channel 3 or 4) depending on your vcr setting and use the vcr to control the channel so when your westinghouse freezes and becomes unresponsive you could still change the channel and so on through your vcr and tv acts like a monitor works for me. N.B be sure to set the volume and so on before it freezes which could be like a 1min window from turning your tv on
