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.

When i turn on my tv it tries to boot, blue mitsubishi home screen come up, i hear fan then it all shuts off while green light blinks.


Try a reset. Start by unplugging for 1 minute, then plug back in & if still won't restart try the following. If none of the following work, you will need a technician.

Initializing the TV in many cases can remedy a problem.
In the 2006 product line Initialization is now a user function.
Pressing the front panel "INPUT' and "FORMAT"
buttons at the same time activates Initialization. When
complete all user settings will have to be set again. The
table in Figure 4-3 list the User Initialization procedures.
Note: Pressing INPUT and FORMAT is the same as
the Initialization in the Option Menu (MENU-2-4-7-0)

My sis gave me an old samsung tv. It is just for my son and his x-box. Unfortunately there is no remote control. When switched on it is saying PANEL LOCK. Is there any way i can fix this. Model No TI-14N3....


hello you could try this The front panel of the COMBI VISION can be locked to prevent it
from being used by young children for example.
1 To lock the front panel, display the television menu by pressing MENU
( ).
2 Select the SETUP option by pressing the P ▲ or ▼ buttons the required
number of times.
3 Press the + button.
4 Select the PANEL LOCK option by pressing the P ▲ or ▼ buttons the
required number of times.
5 Select ON by pressing the + button.
Result: The buttons on the front panel no longer have any effect.
6 To unlock the front panel, set the PANEL LOCK option to OFF.Another option would be to buy a universal remote from say - Argos carefully open it and use your own batteries and use that remote to unlock the TV then return the remote to Argos or if keep the remote if the original is lost. i hope it helps

regards

The timer light keeps flashing but the tv wont come on


ONLY 1 of 2 things can cause this problem----

First thing to do is remove front speaker grill--it should pull out and is secured with plastic pegs--behind it you will find an inspection plate---

Notice the one or two pairs of wires coming from the front keyboard2.gif of the set---remove the inspection plate and follow the wires to the right--you can unplug both plugs(most have two and they are marked with letters and different sizes so you cannot get them wrong)

The idea here is to remove the front keyboard2.gif with its reset button etc from the circuit---You will still be able to try to turn the set on with the remote---

These sets have a Receiver that is called a DM board--(large metal box to the left as you look from the back) and if the power goes out the green light will blink for about 70 seconds and then go out---it is the Receiver booting up. It is called the DM board.

If disconnecting the keyboard allows the set to turn on--you have a bad reset switch and two choices---either operate the set only with the remote or to remove the front screen and get at the reset switch (it is tiny) and remove and/or replace it.

If disconnecting the keyboard does not restore the set to operation---the receiver is bad---there are 4 or more caps and some pico fuses that can fail in that unit---Mitsubishi no longer sells or repairs these--if it is bad and not the caps there is a company you can send the unit to and have it repaired--if you need to know their name let me know---

You can call them and get a quote for repairing the receiver. There are also sites on the internet selling a kit for this repair.

ws65087 or what?

Most of these sets have a self check feature--when power light goes off press and hold both the Menu and Input buttons for 5 seconds and release both--power light should blink a two digit code--like,,,,,,,,2 blinks a pause and 2 blinks---CONFIRM EXACT MODEL NUMBER AND ERROR CODE FOR ME.

Thomson DTI6300-16 digital TV recorder frozen, red light on constantly, no resposnse to any commands. I think it needs a factory reset - how do I do this?


Try Resetting the box to its factory setting:
  • Menu > Setup > Help
  • Then press the Green Button (Even though it doesn't show as an option)
  • Then press the Red button for a full reset
Warning: You will lose all data on the Hard Disk!

I did this when mine wouldn't record anything and dumped all my pre-recorded programs.
Worked a treat.

Convergence


Replaced convergance power packs (2) stk392-110 check all 2watt resistor the packs, to enter the convergance alinment mode on the set. Using the remote control press and release the sleep timer button when sleep timer displays timer equals zero immediately press the display and V. status buttons at the same time.  If done quickly enough the service menu will appear once entered the careful not to does disturb or change any other settings press the number seven to enter the convergence alignment mode a full crosshair pattern will appear in this alignment mode you can adjust the blue and the red to line them on the green using the select and the number pad you can move to the next crosshair to align the boot to the green and then the red to the green when done pressing the muting button on the remote control will save your changes will take a little while to figure this out as you work with.  If you make an unwanted error pressing exit without hitting the muting button will restore your convergence to its previous  setting.  If you're green is off after entering the service mode press the number six on your remote control in this setting will be able to adjust the green only once that is done us the muting button.  Then enter button seven if need be to adjust the blue and the red.  Remember no changes have been stored until the muting button is pushed open this helps.
