Question about Mitsubishi TS-4545 45" Rear Projection Television

1 Answer

TV won't turn on.

I was watching the TV and it turned off by itself. Now, when I try to turn it on (either with remote or with switch on TV), nothing happens. The "on" light doesn't come either. When I try to turn it on, the lights in the living room dim slightly, so I know that it's getting power. Does anyone know what is wrong? This TV is about 12 years old, but I've never had a problem out of it.

Re: TV won't turn on.

It could be your starting cap has a short and insead of building a charge to get the transfomer ot kick ,It may be just drawing more and mor juice with out the discharge ,I wouldn't recommend doing that any more that amount of stored charge may arc to somthing that may start a fire.If you still want to play with the starter,make sure your breaker works or you may burn somthing up outside the tv.Get and Ohm meter and find out if the cap is is shorted out ,ther pretty cheap but I hope you didnt burn up anything like power transitors or the entire transformer,you should make sur they are not shoted before you start bying the starter cap.If you smelt burning wire in the past while trying to start a nice used Tv May be a your best bet ,projections tvs are being replace by lcd even if their real new ,people with $ want to go in the Hole for more space in theit living room

I have a 50" philips magnavox tv that changes channels on it own and turns itself on frequently. What is causing this issue?

Do you live with someone who likes practical jokes; even silly ones?

There are a number of companies that make remotes that can mess with someones TV or other remote devices.
I have a watch, as a gag, that will self program its remote to operate any TV capable of this feature. With this watch, I can change channels, power status and even reset the TV to factory default state.
Next time this happens, look behind you.

TV Doesn't Turn On
  • Your RCA rear projection TV may not turn on from time to time for several reasons. First, check that the power cord is plugged into a working power outlet. Check that the outlet is receiving electricity by plugging a different device into the outlet. If the other device doesn't work, you may need to replace a fuse or reset a circuit breaker in your home.

    If you tried using the remote control to turn on the TV, press the "Power" button on the front of the TV. You may have a problem with the remote control if the TV turns on.

    If you tried using the front control panels and haven't tried the remote, press the "Power" button on the remote control. The television controls are blocked if the TV turns on with the remote. To unlock the controls, open the "Parental Control" menu and remove the check mark next to "Front Panel Block."

    Finally, your TV may be performing a diagnostic check. These checks are used to find any errors in your TV. Wait a few minutes before trying to turn on the TV again.

TV Turns Off By Itself
  • You may find that your RCA TV turns off by itself on occasion. This is often because the "Sleep Timer" feature was enabled. This feature allows you to place a timer on the television that will turn it off after a specific amount of time has passed. The feature allows you to save on your energy bill and extend the life of your television.

    If the "Sleep Timer" wasn't set, the television may have detected a power surge in your home and shut off automatically to protect the components of the television. Wait at least 30 seconds before turning the TV on again.

    Finally, if you suspect the television is turning off for a reason other than a power surge, unplug the television and let it sit for at least 10 minutes. This will clear any errors in the television. After 10 minutes, plug the television back into the outlet and resume normal use.

  • Blank Screen
  • A blank screen on an RCA rear projection television is usually caused by a loose connection or an incorrect setting. Check that the coaxial connection on the back of the television is secure or, if you're using an external device such as a DVD player, the video cables are secure. Press the "Ant/Cable" button to switch between tuners if you are watching television, or the "Input" button to switch between input channels if you're watching something from an external device.

My tv turns itself off while watching it after awhile

if it turns off and the timer light starts blinking you have a bad dm module, very expensive, it the light doesn't flash you have either bad front switches or something on the signal board, you can remove the speaker grill and disconnect both plugs and use your remote, this will disconnect the switches. if it still shuts off, you need baord repair, may be a bad solder connections, may be a chip/board needing replaced, you need a repairman and alot of money at that point.

RE: Sharp Aquos LCD TV, MODEL LC-37D40U Tried to switch the TV on via remote, and I hear the TV turning on, but then it automatically turns itself off again. Tried it several different ways using...

A component is shorting out, and the TV is auto turning itself off for protection. Usually it is a shorted out horizontal output transistor. Only a tech can fix this.

TV will turn on, but not respond

Good Day, mistymiles;

Try this before calling a factory authorized service center:

Press " menu 2 > 4 > 7 > 0 > enter", on remote. After settings have been initialized > press the system reset button on the front, once the LED stops blinking > reprogram settings and tuner channels (if not using box). IF NOT fixed call for service (get estimate before repair) and suspect repair of DM PCB (printed circuit board).

Good Luck, big IRISH.

Hi, I have a samsung le32r74bdx lcd tv and the volume has just gone to 100 and i can't turn it down?

First, start by unplugging set to try to reset. Then make sure that all settings in audio menu are correct. Also look for stuck volume up button on set and on remote. Sometimes buttons get lodged under surrounding frame. Also try to push volume down button on tv and watch for display on tv to see any change. If when you release button volume increases by itself, remove batteries from remote to eliminate it as cause. If nothing you try works expect to replace main pcb. You can probably price it online with model number. Good luck, Russmann.
