    As this is a premium question i'm compelled to answer your question here and not as an ask me question. if the green light is still on it suggests an internal issue, likely a blown capacitor or a power supply issue. if you are not comfortable with taking the tv apart i would have to suggest you have it service at a capable electronics repair shop.

How can I fix my television?


One thing to look for is overheating. Is the TV shrouded and hot to the touch? This is the symptom for overheating but it could be other problems too, such as a broken intermittent connection and also a bad or failing electronic part in the video channel. In any case, quite likely not user fixable.

But 1st check the obvious. Did you make any changes to inputs, hookups or position of TV? Are any inputs lose or bent (TV set top box, DVD, etc). IE, make sure it is the TV and not an input. Try an external input (from DVD etc) and see if that works the same.

If the TV works with an external DVD on any other input (HDMI, RGB, VGA etc) you may ba able to just swap around inputs to bypass the bad input channel.

My ws-55311 shows blue screen on all inputs except the DTV input


This set has 3 hidden menus accessed with a different 4 digit number code----You need the Mitsubishi remote to enter.

One of them is the Option menu which will allow a hard reset of the TV back to factory original---98% of the time it will restore all inputs--cures all sorts of odd problems.

If you have that remote and want to try it let me know for sure the model number and I will give you a link to the instructions for doing it.

How do i get 1080i, my tv shows im only in 480i. i think i might have it hooked up incorrect. my other tv of another brand is much newer so all i did was connect the hdmi cable from the tv to the cable box...


Hello

Your TV will display all High Definition signals as 1080i True HDTV™ and all standard definition signals will be displayed as 480p.

Component Inputs 1-2
YPbPr(480i/480p/1080i)
These inputs can be used for the connection of A/V equipment with component video outputs, such as a DVD player or external HDTV receiver. Please see Appendix B for signal compatibility.
Input DTV (480i/480p/1080i)
This input is used to connect an external DTV receiver, and can be configured for YPrPb and RGB plus H&V signal types.

As a special feature, you have the ability to adjust the red and blue light beams in reference to the fixed green light beam. This process is called convergence. There are two separate memories for convergence. One, for SD 480i/480p signals; the other for HD 1080i signals. SD convergence should be adjusted while watching an SD source and HD convergence should be adjusted while watching an HD source.

Wide Expand: Enlarges the picture, cropping some of the image on both sides. This Expand format is useful to remove or reduce black side bars on HD broadcasts of 4:3 images with black bars. Available for analog 1080i, digital SD 16:9 and digital HD signals.

InputDTV
This input is compatible with most standard DTV and satellite receivers with component video (YPbPr) outputs. Compatible DTV signals are SDTV 480i/480p, and HDTV 1080i. All other DTV signals, such as 720p, need to be converted by the DTV receiver to one of the compatible signal types. Please check the DTV receiver specifications before connecting.
This input is compatible with some DTV receivers using RGB with "separate H and V sync". Compatible DTV signals are SDTV 480i, 480p, and HDTV 1080i. All other DTV signals, such as 720p, need to be converted by the DTV receiver to one of the compatible signal types. Industry standards for DTV RGB signals (systems, synchronization, timing, and signal strengths) are not currently established. These inputs will not be compatible with all DTV receivers that offer RGB, HV outputs. RGB, HV signals with less than 5 cables are not compatible.
If your DTV receiver offers both DTV component video signals and DTV RGB, HV signals, we suggest you use the DTV component video signals. Check the DTV receiver specifications before connecting.
Ok.

Somehow, the Input got switched to RGB,and now I can't get by the blue screen before TV (VIZIO) shuts itself off after posting a "NO SIGNAL". Is there any way to get past that blue screen so I can change...


the brand and model of the tv would have been helpful, but try connecting something to the rgb so it stays on, then use the remote to change the input on the menu or settings.

Green screen


If you are using the component video input change the input setting of the DTV input from RGB to Y, Pb,Pr also make sure the DVR's setting is 1080i output. this set can only except 480i, 480p and 1080i only. also make sure you have the green wire to the green input the red to the red input (some have mistaken the red audio for the red video) and the blue to the blue input.

Connecting component video YPbPr to TV with BNC port for RGBHV


No, this will not work. Picture will roll vertically. Originally they intended for HDTV to be red,green, blue, & Horizontal, Vertical sync. That changed after the first generation mitsubishi's.
In the service menu you can change the settings for the HDTV Input. Try that first by "Hitting menu button followed by 1259" or menu 1257. Let me know how that works for you, If you need a different code for service menu...contact me again and i will look it up for you. But the answer to your question is you can make it work or you can purchase a 300.00 box that will allow you to switch to that input thru..mitsubishi.tv.com
Good luck and keep me posted. GURU JAY
