Mitsubishi WD62530 62 in. HDTV LCD displaying blue vertical lines

Check area around TV for interference--cordless phone--wifi---also check input cords and hdmi cable or coax cable--- make sure connections are tight and secure

The cable box signal on the components video have a too high refresh rate frequency, that is the reason for the lines.
Use RCA cables or an alternative connection.
Other solution is changing the display out settings for cable box (from PAL to NTSC etc.)

Extremely blue color temperature that cannot be adjusted; some false-contouring artifacts in dark scenes; no picture-in-picture; limited connectivity with just one DVI and no HDMI inputs.
If use as a TV monitor:
The number of colors you can display is controlled by the video card installed in your computer. In order to display more than 16 colors, the proper video card driver must be installed. Contact your computer or video card manufacturer to obtain the latest driver from them.
If you are watching standard-definition or Cable/RF signal on an HDTV, the picture may appear to be of poor quality. This is because the TV is designed for viewing HD or at least digital content. Your best bet would be to upgrade to a Dish Network HD receiver and connect it to the TV with an HDMI cable. Similarly inputting analog signal to TV from your DVD player will not appear to be of great quality. A newer DVD player would most likely have component video output which would look much better. To get even greater quality, an upconverting DVD player connected with an HDMI cable would look the best. You could also upgrade to a Blu-ray disc player, which is capable of playing HD Blu-ray discs as well as DVD's at higher resolution. A less expensive choice could also be a streaming media box. Hierarchy of inputs for good picture quality:

Do you have anything to test it in 1080i? Does it do it on all connections or just one? I had a similar problem with my TV that turned out to be a bad input board. Mine would only display 1080i through the Component connections. All others would show pink and green wavy lines. It cost me around 500 to fix it. Unplug the TV. Remove the back cover for the TV. Using a NON-metal object, or gloves, wiggle the input board (that has all the video connections on it) slowly back and forth and see if the problem comes and goes. You will have to have someone watching for you. If something is loose on that board, the problem should show itself. Narrowing down the problem will probably save you money on repair bills.

Sounds like you set HDMI as your primary display device. Try reconnecting to HDMI and use the Mitsubish to make your changes while the laptop is connected. You will need to click the LCD Icon when it shows you the 2 monitors then turn off the HDMI device in that menu. Then select the VGA screen as your primary display device. This can be done with either the displays manager or the optional software supplied with your laptops display. remember to always switch back to your primary video device (LCD) before switching off your PC or laptop since the display resolutions on Hi-Def are completely different than a VGA device as well as the display frequency.
Windows, as well as Bios will prevent your PC from displaying resolutions and frequencies that may damage your Video card.

This is an ongoing problem with Mitsubishi DLP HDTV's contact the Customer Service at 1-800-332-211. Tell them this has been going on for a while and you want the TV either Fixed or Replaced. Ask for Adrianne Hardt, she is a Customer Service Manager...... TELL HER RICK GRIFFITH told you to call.

I am in the 4th week negociations with Mitsubishi over these exact problems. I purchased my 57" DLP HDTV in Aug of 06. Replaced the Lamp 3 times and have had 5 Service calls. I DO NOT have and extended Warranty. Mitsubishi provided me with the extention in writing and stated if any problem occurred again they would replace the Unit or provided monetary compensation.

Good Luck and be persistant.

Any of you can email me for from info and [email protected]

Bad input board BU or AU

Possibly needs a new control circuit board or lcd panel

We have many problems with loose or poorly seated cables and connectors on these units. Pull the back and reseat all the internal cables, especially the LVDS cable to the LCD control bd. If this does not correct the problem the main cause is a bad LCD control bd. or possible a defective main bd.

On your TV set remote are you selecting the proper input; for example when you have different devices connected to the back of your tv set, dvd player, vcr, cable box etc; you have to tell the tv which device you want to use by selecting the right one on your tv remove input selection. Hope this was any help.
