Re: Scrolling

Sounds like it has one of two problems first one could be a stuck button. The micro locks up and the set wont come on also could be causing the channel scrolling run you finger along the channel buttons. Other than that you would need a new signal board you have a locked up micro...this part will be No longer Available.

Mitsubishi wd-73738 turns itself back on


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.

I have a Sharp flat panel model LC-20SH4U. The units power LED light is red. No effect (sound or picture) when remote or on/off switch is activated. The LED light slightly blinks.

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.

Hope this may help;

Hello Jeff;
If the TV does not turn on or off, does not respond to the remote
control or the control panel buttons, or has audio but no video:
1.) Press and hold the POWER button on the control panel for ten seconds. The TV will turn off.
2.) Power on the TV and the green LED will flash quickly for about one minute. The changes you made most recently, before using SYSTEM RESET, may be lost.

If the TV does not respond to the remote control or to the control-panel buttons and TV will not power on or off.
• Unplug the AC power cord for 10 seconds.
• Press and hold the POWER button on the control panel for 10
seconds to perform a system reset.

If the TV turned itself off and the light on the front panel started to flash:
• Momentary power fluctuation can cause the TV to turn off to prevent damage. Wait for the green light to stop flashing and turn the TV on again.
• If the TV does not stay on, press the POWER button on the
control panel for ten seconds to perform a System Reset. If this happens frequently, obtain an AC line power conditioner/surge protector.
• An unusual digital signal may have been received, triggering a
protection circuit. Wait for the light to stop flashing and turn TV

If the TV will not power off, press the POWER button on the control panel for ten seconds to perform a System Reset.

I would not recommend using compressed air or any other method that would blow dust around- since the dust could make its way into the set's circuitry via the grille or vents and cause problems. Use a vacuum cleaner with a brush attachment instead.

When my tv is powered on, it displays the device menu and continues scrolling through it, but will do NOTHING else. I've tried to reset, and nothing. The tv will not respond to the remote at all.

A suggestion here: If possible to remove front speaker grill and inspection plate that should be behind it---locate the bundle of wires that comes down from front keyboard with the buttons and follow it to the right and down---should be one or two plugs in-line--------disconnect them with the set off and power set back up with remote.

If the problem is gone you have a bad micro-switch on the front of the set------buttons on the keyboard there have priority over the remote---hence you cannot if the problem is there stop it with the remote or do anything for that matter.

Let me know what happens and I will suggest options.

My Hitachi 57F59 was scrolling thru the channels without anyone touching the remote - I unplugged it for two days and now it keeps flashing the

Keyboard issues and answers:A problem that is more common than most people think is an issue with buttons on thecontrol keyboards of modern TV sets.
Recently for whatever reason I have seen more questions about this so I have composed this answer and solution for these kinds of problems.
It can be any button on the set-channel up/down or volume up down-you name it.
The symptoms are the same: channel will scan up or down andwill not stop-remote control has no effect on this---It can be channel, volume,or even input or menu if the set has those up front or on the side of the set.
All these push controls have something in common-beneatheach is a tiny momentary push switch-when pushed with the plastic button itperforms a specific task (vol up or down etc.)

What happens is the afflicted switch beneath the plasticbutton is bad-when released it is supposed to stop its function but does not.
Keyboard or button controlled features have PRIORITYover the remote control, hence the remote will not stop this fromhappening.

Both the remote and thekeyboard go to the microprocessor in the set but keyboard is first in line.
How to resolve this issue?
Someone needs to get at the tiny pc board with the buttonsand locate the one associated with the issue (ie sound or channel etc) andunsolder that switch from the board-usually just two pins (may be more formounting only purposes) and then see if set does not have the issue with switchout of the circuit.
For the TECH minded with the board out test here theswitches with a ohm meter set to high resistance-any reading with button notpressed means a bad switch-seen ones that read 5,000 plus ohms-it may benecessary to unsolder more than one switch to locate the offender here but an open reading with switch not pressed is therule.
I have taken the time to compose this answer as some do notunderstand what is happening in these types of situations---No magic wand orsmoke and mirrors here-have to disable the offending switch to know.
The beauty (in my view) of this kind of problem is if found, you really do not have to replace anypart-just operate the set with the remote with one button that no longerfunctions on the set itself-who could ask for more?

Mitsubishi WS-65611 tv channels cannot stop scrolling

Check to make sure the channel down button is not stuck. If it is not the button is probably defective. Mits has had a lot of problems with the buttons.

the circuitry within the TV is where your problem is. thats why your remote wont work it either. Could just be he wire arent pluged in completely or you could have a bad resistor on the control panel PC board. Hope this helps. Let me know if I can assist you any further.
