Re: Set will not come on; timer light only

Ok you have fault oscillation inside and you have defective parts! the problem is power oscillation! the trouble is in the power section (hot and cold) or the jungle IC circuit.

Timer light is flashing on front panel. Manual

If you know your way around the inside of the set, take the back off, Plug in the set and watch to see if the fans fire up, do not touch anything in the bacjk while the set is on, remember your just looking. Now if you have a good visual you may also be able to see if there is lots of dust build up in or around the fans, if so unplug the set and carefully use a portable vacume on each fan, plug it in and see if that helped, if not replace fan, if you can see which one that needs to be replaced, failing that call a tech.

Worked fine this morning. Unplugged it to rearrange. Plugged it back in and the green "timer" light flashes and it will not turn on. Any ideas? Thanks, Bill

bill! any time that you have power turn on issues, you should make sure that you have the proper ac supply voltage at the wall outlet. plug in a lamp at the same outlet as the tv set!. if it works unplug the tv set for a few minutes to attempt a reset of a possibly bad turn on relay or power circuit. try turning on the set by the power button on the front panel. then try using the power on the remote control. each time listen for a click of the power relay and static build up for the high voltage circuits. if you have niether! unplug the set and open up the back bottom panel and check for a open fuse any where on the the circuit board. now bill put on some rubber dish washing gloves before you attempt to replace any fuses upon reaching onto the circuit board suface area. there is a danger of electric shock! at the projector picture tubes an the flyback tranformer areas. if you find any blown fuses and intend to replace them, they must be replaced with ones of the same voltage and amperage rating or your could cause a fire and burn up your set or your home. if the fuse at the ac line cord circuit is not blown ,then you have a open on short circuit in the high voltage section of the set. replace the blown fuse and power of the set again, if it should blow the fuse then you need some professional help unless you are familar with testing and changing out the horizontal output transistor in which maybe causing the short.

I have a Misubishi model# WS-55859 & SERIAL# 107540. The timer light blinks rapidly and the TV win't turn on.

if the timer light just blinks all the time unplug the set and wait a while---if the set has a receiver built in(from the back of the set it is a large metal box on the left side ) the light should blink when you plug the set back in and stop after about 70 seconds---if it does not stop blinking you have either a problem with the receiver or the micro switch for RESET on the front of the set.

easist way is remove front grill and unplug the one or two plugs that come from the front keyboard---set will still turn on with the remote--if it comes on this way--problem on the keyboard--if not it is a bad receiver(very expensive)

If this was at all helpful give me a vote here--I do this for free.

Mitsubishi VS-50609 won't turn on

What a great tv this is Mitsubishi did a fine job making this one, but......only an authorized mitsubishi servicer should repair it. This set records diagnostic led codes that the technician receives to help determine where the problem might be, not the problem, but in which circuit it might be. The one thing to try is, unplug the tv , let it set for a minute, plug it back in , turn it on and hope it reset the micro. Next , call for mits. service.

Timer light blinks on and off and tv wont turn on

Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.
1. Unplug the TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.
If ever resetting is no effect then the problem is in the "DM board"
The constant blinking green light means that the TV is not booting up. This is a common problem on this set. Hope it may help you; Regards, VOTIT

No Power.

You might have blown a fuse inside the TV. Lots off volts can go into those TVs. Make sure you are under warrinity and return the thing. Maybe also a malfunction.
