Question about Mitsubishi WS-55819 55" Rear Projection Television

1 Answer

LED Blinking The LED below "timer" on the front panel was solid green. I held input and menu for 8 seconds and the LED stayed green until the TV turned off. At that time, it blinked twice and turned off. TV would not stay on for 8 seconds following my first try.

Okay 2 blinks isnt a error code, so your set isnt shutting down due to a protection issue, so I would suspect one of the low voltage regulator transistors or the horizontal output transistor as being defective

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)

I fixed the blinking light, but still no picture


The constant blinking green light means for one minutes and then goes solid green, that the TV is not booting up. This is a common problem on this set.You need to remove the shield from the DM board (standing upright on the left where the DTV RF connector is)and inside you will see the four leaky capacitors (1000 MFD 16 VOLT)replace them,plug the TV in and wait 70 seconds for the blinking light to stop,then turn on the TV.The hard part will be removing the board from the TV(lots of screws and connectors,takes time)

a3d2d2a.jpg You must do some checks first:LED does not stop blinking after plug in. Verify the standby supplies, 12-volts at connector KA pin 17, 6-volts at KA pin 18 and the 28-volts at KA pin 19, if the supplies are present suspect the DM PCB part # 934C067001 LED does not stop blinking after plug in. Check C9B01, C9B02, C9B10, and C9B11 (1000 UFD 16) on the DM PCB, if they are bad replace them with part # 181P734030 (680 UFD 16 V). LED stops blinking after 70 seconds of plug in but will not power on. This model is equipped with a keyboard lock feature; this can be mistaken as a no power condition. To unlock the keyboard press and hold the "menu" button on the front panel for 10 seconds . LED stops blinking after 70 seconds of plug in but will not power on. Check for 3.2 volts DC at connector RF pin 4 and 5 on the Signal PCB if low suspect problems with the switches/buttons on the Control PCB part # 935D736001. LED stops blinking after 70 seconds of plug in but will not power on. Keyboard is not locked and key inputs at connector RF pin 4 and 5 check good suspect the E2P PCB part # 934C061001.

I have a Mitsubishi WD-62725 TV and i cant get the Tv to turn on. the green timer light is constantly flashing quickly and the tv will not respond to me pressing the power button.


Good Day, remicarlson;

This is not the easiest problem to solve. I will give some ways to troubleshoot you TV for today and for future.

I would though recommend that you seek an authorized service center to do this.

HERE ARE THE THINGS TO CHECK:


1. Red status LED, self-diagnosis error 44, check for open F9A06 on the Power PCB part # 283P128050 on the Power PCB 2. Red lamp LED, self diagnosis error 34.

This model is equipped with a keyboard lock feature, this can be mistaken as a no power condition. To unlock the keyboard press and hold the "menu" button on the front panel for 10 seconds 4.

does the led blink? If not try pushing input and menu both in together on the front panel and hold in for 8 seconds to see if the led will blink a two digit code.

Blinking Green Light on Mitsubishi DLP 52525


Even if you replace the capacitors already mentioned in this
thread, you may still suffer from the Green LED of Death. Here is how Bronson279 helped me resolve the
problem. But note that it involves
adding a switch to your tv set and requires a bit of soldering ability and the
willingness to void your warranty. BUT
you can save big $$$$ on sending the set out for repair.

Here is my solution-
After replacing several bad capacitors (you can get replacement capacitors
from Mouser electronics on line by the way.. be sure to order the same capacitance
values and same or higher voltage rating and be sure they are rated for 105
degrees C.) I still had the dreaded G.L.O.D. Note that the first time I plugged it in
after taking it apart the G.L.O.D was not there and it powered up
normally. But when I had to unplug the
set to fully re assemble it, it came back.




The issue is caused by both the FMT board (formatter) and
the DM (Digital Module) board’s microprocessors tying to establish
communications with each other. Somehow a race condition gets started with each
thinking that the other board needs to be reset and then starting the boot
process over again.





You need to interrupt this cycle with a switch. Buy a DPDT switch from radio shack (or Mouser
Elec…) and again take apart your electrical chassis (If you have it apart
replacing bad caps you might as well add the switch or you may end up having to
disassemble the whole thing again.) On
the FMT board along the top edge near the input connector side of the chassis
there is a four wire connector labeled “FC”.
It has two black wires and 1 orange and one Brown wire. Leave the black wires connected and cut the orange and brown ones about an
inch from the connector. Solder four 12
inch wires onto the ends (one on the source side brown, source side orange and
one on the connector side brown and connector side orange) use heat shrink tubing to cover the solder
connection points. (If you can’t get tubing, then electrical tape will do, but
make sure the joints can’t short out to each other or the electrical chassis.) Now take the brown and orange wires from the
connector side and solder those to the middle two terminals of the DPDT switch
(one on each side not both to both terminals) Then pick one side of the outside
terminals of the switch and solder the source side brown and orange wires to
the terminal across from the same color (brown across from brown and orange
across from orange) See the diagram below.
The idea is to connect the wires normally when the switch is closed and
break the connection when the switch is thrown the other way. Before soldering
the wires to the switch add a piece of heat shrink tubing to wire so that you
can cover the solder point up after it is assembled.

























45186c7.jpg






Now re-assemble the electrical chassis and route the switch/wires
outside the chassis (I snipped a hole along the edge of the top fan shield to
get the wires out.) and put it back in the TV.
You need to also get the switch to the outside of the TV somehow (I
drilled a ½ inch hole in the plastic cover to snake the switch through but you
can do it however you like)





Here is how to use it-
From a fresh plug in- throw the switch to the OPEN position (the wires
are not connected) plug in the TV, the green LED should stop blinking after 60
secs like it is supposed to. Once it stops, flip the switch the other way so
the wires are connecting. Hit the power
button. The TV should turn on- your done!
Yeah!

From a plugged in, hmmm my power must have gone out,
state. Assuming you have the GLOD, flip
the switch to the open position, hit the reset button on the front of the tv,
wait for the blinking to stop, flip the switch back closed and turn the TV on
normally… Again you are done…

Note that the first time you turn on the TV you may have to
flip the switch the other way (if the TV won’t turn on even without a blinking
LED) This means that the switch was open and you need to have it closed to get
it to work. If you tried turning on the
TV with the switch open, start over by following the reset button procedure
above.

Note this is much easier to do than it sounds. Also note that it helps if you have the
repair manual. Its titled V26 Repair
Manual –full This is nice to have
because it has a wiring interconnect diagram also which details all the
connector placements
