SOURCE: Flashing green light when i hit power botton.

2 blinks and 2 blinks is the error code for short protection---usually in this set the most common cause is a bad convergence chip that has shorted; it takes out one or two pico fuses in the set's power supply---the set detects no voltage to the convergence chips and shuts down.

Almost any good tech can do this repair in your home in about a hour or less--shops charge 300-400 for this kind of repair--look in your area and find someone who has done this brand before--I do lots of them here for 200-250 depending on model---This is the slow time of year for TV repair shops so look around--if someone says it "has to go to the shop" keep looking.

I have detailed start to finish instructions (verify the model number to me) for doing this repair; If you have the skill to do it yourself--you can buy the chip on Ebay A WS-55809 model uses a single STK-393-110 chip---about 14 dollars on Ebay plus shipping----let me know if you want the instructions and if you have questions reply to this post here.

I do this here for free so if it helps you take a moment and give me a vote here.

SOURCE: ws-65315 won't turn on

Need to know more, 1-2 is no error code, you say will not turn on, do it has led light on or do you hear sound in set like high voltage? Any lights blinking? Or just completely dead, like fuse blown?

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.

I have a mitsubishi ws-65315. When I go to turn the tv on the green power light comes on and you can hear the tv click on, but seconds later shuts off.

this model has a self check, when green light comes on and then goes off. Push and hold both the Menu and Input buttons on the front of the set for at least 5 seconds and release both.

Power light will blink a two digit error code like 2 blinks 2 blinks, a pause and then repeat it several times.

Let me know what error code you find and I will tell you what it means.

I have a Mtsubishi ws-65315... I hit the menu and input and after 6 seconds, it blinks twice, then pauses for a second, blinks twice again, another pause, and does this 4 or 5 times... Can anyone help me...

Most likely convergence circuit is out. Two convergence amps have to be replaced as well as some PICO fuses that already open. I would strongly recommend to let professional do this repair, without experience you can damage TV and make it unrepairable.
It should cost you around $300 to fix it at your home.

Tv mitsubishi ws-65315 doesnt turn on,only green light

Good Day, cutito35; 1. 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. 2. (Power LED may be on after plug in) check for no less than 4.4 volts DC at pin 3 of PC9A21 on the Power PCB, if low or missing replace PC9A21 part # 268P058020. 2.This model is also equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source) 1. Shutdown at power with self diagnosis error 2-2. Check for open fuses F9A04 and F9A05 part # 283P144080 on the +24 and -24 volt lines. If the fuses are open the convergence output circuit would be suspect. 2. Shutdown at power with self diagnosis error 2-1. At power on check for 12-volts DC at connector KH pin 8, if missing check IC9C51 part # 270P990010 and L9C52 part # 441D009020 on the Signal PCB. Good Luck, big IRISH.

WS 65315

ok 12 means no error detected so your set must have a standby voltage problem which is preventing the set from powering up. possibly a low voltage regulator is defective.
