Question about Mitsubishi WS-55511 55" Rear Projection Television

1 Answer

TV will not switch on, green light flashes for 30 seconds but it still does not come on.

We had the local power company cut the power for 2 hours. The TV was on when they cut the power but we have a surge protector on the power input. The green light flashes for about 30 seconds then goes out and when you press either the remote or the TV power on button it still does not come on. I have tried several times the reset button and still nothing. I have disconnected the control panel wiring and still the green light comes on but the remote will not switch the TV on. Anyone got some suggestions for this problem. I have not replaced the fuses (not sure where they are located to be honest) but I don't think this is the problem as there was a surge protector on the unit and all the other electronic items on the surge protector are fine. We have had a friends little girl round and she loves to touch the TV and the buttons so I thought maybe a button was stuck but disconnecting the 9 wires on the connector from the control panel that goes inside should have sorted this problem out. I love the TV but it is frustrating that it does not work. Please somebody help me!!!!!

Know problem of bad caps.
replace DM

Picture of bad caps

The DM board is the one with the digital connectors on the back panel. If you already have it appart, you may as well check the caps on all of the boards. The caps that go bad are typically Jamicon brand caps in 1000 uF and 330 uF values. There are also a couple of 3300 uF caps in the PS that cause problems.

Panasonic PT50LC14 Power issue

We have a PT-50LC14. We replaced the lamp 6 months ago with a TY-LA1000 bulb we bought from a company online (not directly from Panasonic) and it worked for 6 months. Then the TV started turning off on it's own...sometimes it would not come back on for an hour or so. We called the lamp company and we luckily had 1 day left on our 6 month warranty!! They sent us a replacement bulb and the TV would never power on. It would try to power up, but the bulb would never ignite. The power light would flash and then the lamp light would flash every 5 seconds. I had a friend that has the same type of TV and she ordered her bulb directly from Panasonic. I borrowed her lamp and it powered right up. We then called the online company and they sent us yet another replacement bulb, and I tried it today and it works. It seems like these TVs are very particular about the type of bulb used. Next time, we will be ordering ours directly from Panasonic and just paying the extra $100. We have been without our big screen for 2 very long months! I had called a local tv repair shop, called Panasonic directly, and read through countless internet forums, and I thought we were going to have to replace the ballast or get a ballast repair kit and start messing with the circuit board.

Power/Standby light blinks green then screen goes blank (off) for

I have a similar problem. Just found out a possible solution yesterday. I am waiting for my lamp but here's what you need to do if you have replaced your lamp. Go into self diagnostics mode: Switch of your TV via remote, you will see red standy by light. Now,on the remote press "Display"=>"Channel 5"=>"Volume Up"=>"Power Button". All these keys need to be pressed within 3 seconds. You will now enter the diagnostics mode. Press "Jump" on remote (bottom right) 3 times and then press "Channel 2" 9 times. The screen will display your current lamp hours used.

In order to reset your tv to factory settings and for the new bulb to work you must reset this timer or else your TV will assume you are still using the old bulb and will automatically kick in "over protection mode". So here's what you do once you do on the lamp hours display screen. Press the "Channel 3" button on the remote 3 times then "Mute" then "Press Enter" to reset the timer to zero. Your TV should now work as normal. And remember, whenever a part is replaced all factory settings must be reset to zero. To do this, follow "Display"=>"Channel 5"=>"Volume Up"=> "Power Up" to enter service mode. Finally, press "Channel 8" and then "Enter" to put the TV back to factory settings.

The above mentioned is usually performed by a service technician and they charge somewhere around $95 diagnostic fee. You just saved this charge. If you see flashing red lights count them when they flash in sequence. This is a code for the techs to tell them what is wrong. These flashing red lights sequentially flash from 0 to 10 times to identify a problem. Usually, when the bbulb goes bad the only thing that might need to be replaced would be a "lamp Driver" aka "Power Block Assembly" $116.25 online from Sony, or the ballast. Sometimes, if you do not have a video a Thermal FUse can go bad which only costs $4.80 for the KDF60-XS955 but the techs will charge you over $300. You can do this yourself if you can get your hands on a service manual.

Hope this info helps.

Good Luck to you all.

Tv cuts off and green light flashes

Yup, it seems a lamp problem can give a blinking green light over the 10 times (1 - 10 times for diagnostic codes), but in my case rather than replace the bulb if it works for a minute then resets with the green light blinking, do what I did.
Take the lamp out and inspect it, it has breather screens top and bottom, if it cant breath because there clogged with dust, clean them, and you can remove the screens, use q-tips and clean the inside. I saved the cost of a lamp and it's working fine!

Tv only 2 years old

I don't know your set in particular, therefore I will be generic.

On some projection sets, there is an hours counter that is manualy resetable. Make sure that it is reset. If you can have a readout of the amount of hours used on the lamp this will tell you if this needs to be reset.

Normaly, when the set reacts as per your description, there is a cooling problem, or a fault in the power supply.

Also with your model of set, check to see if there are any safety switches that work with the cover or door for the lamp access. With the safety switch option, if the uPC thinks that the lamp is not properly enclosed or installed it will not allow for proper startup.
