See this link.

this is the similar problem as yours.
You could have a problem in the DM board assembly. First thing to do is open it and see if the DM power supply capacitors are swollen or bad. This could be a very costly repair unless you know how to solder and work on printed circuit boards. If you do not, play it safe and call in a pro to assist you in this repair. Good Luck

i know BDG has already posted the same post.

thank you

This looks like it could be a problem with the DM board assembly. First thing to do is open it and see if the DM power supply capacitors are swollen or bad. This could be a very costly repair unless you know how to solder and work on printed circuit boards yourself which if you don't, then take it in to get repaired. Be careful not to touch anything that you are not familiar with as the power in the unit can hurt you.

On my Mitsubishi HDTV 1080 series integrated, when I plug in the power cord the light on the front just keeps blinking and there is no picture or anything. Can you tell me what the problem is?


The DM capacitors have failed which causes the led to blink non stop green. Replaceing the DM caps will usually repair the issue. But need the model number of the set to assist you further.

Tv goes off, then comes on, and volume goes to max


OMG! Verizon Fios at it again with changing boxes! Well let me tell you if you do not loose signal on a DVD using these same inputs ITS NOT YOUR TV!

Whats going on is further into Verizon system you loosing the signal from the VDSL slam outside in the pill box. This thing will need to be replaced and they are going to blame your TV until you just give up and buy a new TV only to figure out its not your TV.

1. Call them back
2. tell them to check there network
3. if that dont work tell them to check it again
4. if you have HDMI use that instead of the scart connections.

I hope you have luck with Verizon Fios there internet rules but there TV service is sub par!

Thanks

Picture and sound go out and remote isn't working properly


Take the original Mitsubishi remote and remove the batteries. Install new fresh batteries and then try to operate the set. Do not try to use any of the inputs that are active. Just check menu funtions with the mits remote. All kinda irrational stuff happens when multiple and universal remotes get involved. If this a model remote that has a selector switch at the top for choosing tv/sat/vcr, etc make sure it's on tv.

My xbox360 Wont work on my WS-55513 MITSUBISHI COMPONENT


Try changing the settings on the Xbox under display to 1080i. If it is 1080 p, or 720p, the image will look funny so make sure it is at 1080i.

Your welcome
