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.

MITSUBISHI WS-73909 will not turn on 1. I have a Mitsubishi Big screen TV model no WS-73909. Few days a go the city power went out when the TV was off. The TV had a surge protector. Then the TV will not go...


Are you a Quailified Technician ? Because this repair is not for the novice. The best thing I can tell you is contact a Mitsubishi Authorized repair center or tell me what area you live in and I can find one for you. cost is 250-350 to repair.

Mitsubishi 1080 hd ws-65809 wont power up


This issue is almost always caused by a faulty Convergence IC inside your TV. These chips heat up and can become damaged over time. The most common cause I have seen for the picture distortion is the heat of the Convergence IC weakening the solder connection to the TV circuit board. If you look on various messages board you will see people rigging wooden dowels and other items to apply pressure to the chips in order to correct their picture issue. This works because when the solder joint is weakened the chip becomes loose and vibrations or pressure will cause it to work or not work correctly. Aside from all that information the correct fix is to have the IC chips replaces on your TV.

The solutions for this issue are as follows:

1. located a tv repair shop that will replace the parts for you. I had the same issue with my 65" Tv and the quote was $350 for the labor and parts.


2. You can ordered the IC replacements yourself online by going to google and looking up a reseller of the STK392-110 Convergence IC that is inside your model TV. You will need 2 of them and they cost around $6 each. If you have the soldering skills to remove the old chips and install the new ones this is by far the most cost effective route. It is a fairly simple process and guides can be found online.

Dm board (power supply) for mitsubishi rear projection tv (ws-55807)


Good day,

mohiuddin;

If the indicator stays on then you may have an DM PCB problem and to correct this do the the folowing:

SYMPTOM: Power LED does not stop blinking after plug in.

CURE: replace C9B01, C9B02,C9B10, and C9B11 (1000 uFD 16V) on the DM PCB. Replace them with part # 181P734030 (680uFd 16V).

The DM Board (PCB) is located on the very left side of the TV looking from back. Caution on removing Board and note what cables you disconnect to access the Metal Shielded Board.
Good Luck, big IRISH.
