Question about Mitsubishi WD62627 62" HDTV

2 Answers

No luminance We have a very poor dark predominantly red picture through the HDMI port. No video can be seen when trying to view input from any RC jack inputs. There is no change in video when contrast or brightness adjusted up or down with input from both HDMI port or any RC jack input. What video can be seen from the HDMI port can be adjusted from nothing to poor when adjusting the color adjustment. The menu can be seen perfectly. There is the same problem as the RC jacks when attempting the tuner input. Audio works fine. The TV boots properly with no flashing lights. The TV is two years old and has been trouble free. It is used on the high end of normal. It is getting close to lamp replacement but there has been no degredation of image, this was working one day the next morning, no video or very poor video.

    Are there CRTs in a DLP television?

  • BRJohnson Feb 10, 2008

    Yea it looks all red and nasty but that is on the HDMI port only and it wasn't a slow process, it happened overnight.

    Hey Nick, I replaced the bulb and no go. It may be a bit more of a crisper bad video but predominately red and still no luminance. The only video that can be seen is through the HDMI input still. No big on the bulb replacement we were getting close anyway. Anymore ideas?

Hi,

if everything else works - there is sound and high voltage (static on the screen) - but there is no picture (including no on-screen menus), this limits the likely area of problems is the video output circuitry or CRT filament connections. Check to see if the CRT filaments are glowing. If they are not glowing, check for bad soldering on the CRT neck board and around the flyback transformer. Where the picture is erratic - coming and going entirely or changing brightness suddenly, with power off, remove the picture tube socket (carefully!) and clean the pins with fine sandpaper and use contact cleaner on the socket. This source of bad connections can result in a variety of erratic symptoms. Check for bad solder connections on the CRT neck board.

Is there anything else i can help you with??

    sorry for that..

    The problem can be with the bulb as nick said but if you have nothing on the screen at all?? not even menus. then you need
    a repair. there are several parts that could cause this. the most
    common is the ballast that fires the lamp. a repair cost for this is
    around $400-$500.

How do I hook up a HD satallite dvr to a av reciever dvd player and HDTV using HDMI cables


Things You’ll Need:
  • HD television
  • HD satellite or cable receiver
  • DVD player
  • Stereo receiver
  • AV cables
  • Cable connector
  • HDMI cables
Step1Examine the back of your HDTV. You will see a series of input jacks for AV cables, (typically color-coded white and red for audio and yellow for video), as well as an antenna input and one or more HDMI input jacks. There will likely be a number of them, but each one should be distinguished with a label ("video," "cable" or something similar). Step2Attach the cable connector from the cable or satellite receiver to the antenna input on the back of the TV. Step3Connect the AV cables to the DVD player, VCR, stereo receiver or whichever other component you wish to connect to the television. The cables should line up by color: place the white cable in the white input jack, the red cable in the red input jack and the yellow cable in the yellow input jack. All three cables from each component need to go into the same label input jacks. Usually, they will all line up in a vertical row. Step4Find the HDMI output jack on your receiver or DVD player (some receivers will not have them--they are necessary to receive a high definition signal--but can still play on the TV through the cable connector or AV cables). Attach one end of an HDMI cable to the output jack of the receiver and the other end into the input jack on the HDTV. Step5Turn on the TV. Access the menu with your remote, and follow any instructions it gives you. Your HDTV may require a few additional steps to complete the hookup of the receiver (though not all of them will). Step6Access the "input" button on your TV remote. This will allow you to switch the TV signal to one of the cable connections you have just made. For example, if you attached the HDMI cable to the first of two HDMI input jacks, the TV will flash "HDMI 1" on the screen to tell you that is where it is receiving its signal. Hope that helps..........

How do i hook lap top up


Most Laptops have a VGA output port. You would just hook this to the VGA input of the TV for video (picture).
You would then need to hook an audio cable from the laptops headphone jack to the TV's VGA's Audio Input jack.
Newer laptops have a HDMI output so that is easier and can hook directly to the TV's HDMI input for both video and audio.

Hitachi RP CRT Gone Red On All Inputs!!!


I want you to do a simple visual check of something that will tell me what the problem may be.

Go to a channel that is in black and white--old movie and tell me what color the screen/picture is.

You can also turn the COLOR in the customer menu all the way off and look that way.

What we are trying to see here is if TRACKING is set correctly or has changed. If the screen is somewhat to medium reddish it may be an adjustment outside of the customer menu.

Let me know what you find--I have seen several of these where the black and white picture was somewhat red--the idea is it should be as close to black and white as possible--if red is the predominant background color the picture will look reddish.

If this has helped and you confirm the red instead of black and white picture--I can tell you a easy way to adjust this.

If this information told you something you did not know and helps you rate this solution as I do this here for free.

How can i watch movies from computer to my tv


You probably need to get a composite video output card for your computer. Actually, I've seen many cards that have both a composite video output AND a DVI output port on 1 card. The DVI output will give you a noticeably sharper picture than composite video, but you need to check if your TV has a DVI or HDMI input. (If it was manufactured after 2000, it probably does.) If you TV was manufactured after 2006, it probably has 1 or more HDMI inputs instead of DVI. You can buy a DVI to HDMI converter cable. That takes care of the picture; to get sound to the TV, you will need to connect separate sound cables to your TV. Your computer needs to have a line-level output jack on it's sound card, and you will need to get an adapter cable (from Radio Shack) to convert the stereo mini-plug to 2 RCA type plugs to plug into your TV. And that should do it!

No video with HDMI port


try 2 things, first use the rgb cables or video (yellow) cable and plug it into the tv using one of the imports..(vid 1,2,3 etc...) and see if that works. then check to see if you get a picture by not using the cable box, by pass it and connect it connect it in the uhv channel. also make sure you have it on the right input of the tv (meaning scroll through the input button on your remote to find the picture...i've done this a million times). still no picture try your dvd player input and if you have a vhs input see if that works. if it is the hdmi input...to be honest it's expensive and a pain to replace...
