Question about Mitsubishi WT-46805 46" Rear Projection Television

1 Answer

Tv turns on and then quickly off

When we turn the tv on through our cable source, you can hear the tv try to turn on but immediately switches off. I tried holding in the on/off button and although you can hear it trying to turn on, it won't stay on

You most likely have a fluid leak from the CRT's. That is a common problem with models ending in 05

No signal is the only thing that will come on my TV


What is the signal source? How do you have the TV connected to the source?

For most video equipment (dvd players and other set top boxes), connect the TV to the device with everything turned off. Turn on the TV then switch to the appropriate input. Finally turn on the source device.

Check the cables to make sure that they are fully seated. Try using different cables (to rule out damaged cables).

If your source is OTA antenna, check that the antenna hasn't been rotated. (This assumes it has worked in the past.) Check your wiring for any damage. If you have an amplifier or switch in use, remove it and check if the signal comes through. (You can use a coax coupler to connect the two wires directly). If the signal is fine, replace the amplifier. If you were using a switch, either replace it with a direct replacement or with an amplified switch (in case the signal was reduced beyond the level that the tuner can receive). Also check if the fuse has been damaged, if you have a surge protection/grounding system on the antenna system. Replace the fuse if needed (this can also be the issue for satellite and some cable installs).

If your source is a computer, try a different video cable. Turn off everything before connecting the TV to the computer and turn on the TV first when ready to restart. Make sure that the video port that you are using is active. (Desktops often have on-board video and separate video cards. Only one set of ports is live.) Depending on the computer, you may need access the BIOS with the computer connected to a different monitor to change the active port. (Press Esc, F1, F2 or F10 depending on the machine immediately after turning on the computer. Sometimes I miss the timing and have to shut down the computer a second time and repeatedly hit the key to access the BIOS.) Make sure that the computer is sending a resolution of 1360x768 at 60 Hz.

If you are connecting a computer to the TV with an HDMI cable, try using the VGA (RGB) port instead. The computer's signal is not the same as that of other video set top boxes. This TV does not support a computer on HDMI.

For a laptop, you also may need to enable the external video port. Then set the OS to use the external port. (On my HP laptop with Windows 7, I can do this by right-clicking on the Display and choosing Graphics Properties. Then I can set the monitors to Dual, Extended (mode) and Laptop monitor or External Monitor (display). Then click Apply followed by OK (in a second window) to accept the changes. For other laptops, you probably have a shortcut or can do it in the OS.

If the problem occurs on all sources, the input board may be damaged on the TV. (A power surge (lightning strike) could cause the damage.) If the TV is under warranty, you should contact Vizio.

Since the inputs are directly soldered to the main board on this TV, unless you are skilled at soldering, you would need to replace the entire board. Disassemble the TV and check the current board before replacing. There are several main boards available for the TV. Shopjimmy.com lists the VA220E parts as out of stock. Partstore.com has some of the boards in limited numbers: http://www.partstore.com/Model/Vizio/Vizio/VA220E.aspx .

I hope this helps.

When i go to hook up a hdmi cable to my philips flat screen it wont recognize that i have a hdmi plugged into it. so what could that be the tv? the hdmi works with my other tv though


Hi,
This model has 4 HDMI inputs, do you get same problem in each HDMI input?
Did you checked HDMI input with any other video source like dvd player or PS3 etc instead of cable box?
Below are few helpful tips to connect HDMI input..
1. Ensure that your HDMI cable is certified.
2. Press SOURCE on the remote control to switch to another source and then switch back to the HDMI source.
3. Reset the accessory device and the TV.
• Turn on the TV
• Select the HDMI channel
• Turn on the accessory device
4. While the TV and the accessory device are powered on, unplug either end of the HDMI cable and then reinsert the cable.
Try above options and if tv still does not show picture of any video source through HDMI then it seems problem of HDMI processor located on main board, visual check is needed by qualified tech or call Philips if tv is under warranty.
Hope these info will help you.
Thanks.

Can hear volume on tv but cannot see picture...tv flickers like it wants to come on but it does not....screen is dark and continually shows hdmi like it wants to come on. the tv before would turn on after...


Many people who use A/V receivers use them to switch only the audio. ie, hook up all your video sources to the TV, and switch between these sources using the TV remote. Just connect the audio cables from your video gear to the Onkyo. The reason is that video signals are more susceptible to problems in A/V receivers than audio signals. better to connect the video sources directly to the TV.

You may want to ask for more clarification about this.

TV displays RGB code and then displays, no signal and then shuts off. What does the RGB code mean?


It means the source is not set correctly. Switch the source to input 0 (cable or antenna depending on your particular set up).

I have a 19" phillips lcd tv and when i turn the tv on the phillips screen comes up but when it is going the show the channel it shut off by itself how can i fix this problem?


Hello. I may be able to assist you. If you are using a direct cable connection from the wall outlet;
  • Check the incoming cable or antenna signal connection to ensure that it is properly secured to the TV's antenna input.
  • If the connection is good, perform the automatic installation again to search for all available channels.
If you are using a coaxial connection from the Cable or Satellite box to the TV;
  • Set the TV to the channel specified by the service provider.
  • Change the channels at the Cable or Satellite box to view the program.
If you are using a video connection (CVBS, S-Video, YPbPr, HDMI) from the source (DVD, Cable or Satellite box) to the TV;
  • You do not need to perform automatic installation to search for the channels.
  • Press the 'SOURCE' 071218044349_22024.gif button on the remote control repeatedly to select the correct input source.
If you are using an HDMI connection from the source (DVD, Cable or Satellite box) to the TV;
  1. Reset the TV and source by unplugging it from the power outlet for 30 seconds.
  2. Turn on the TV and press the play button on your source device. If the source is HDMI CEC compliant, the TV will automatically switch to the HDMI input.
  3. If your source is not HDMI CEC compliant, turn on the TV and switch to the HDMI input.
  4. Turn on your source.
If you are sure you have selected the correct input or channel but still have no picture or sound;
  • Try resetting the TV by unplugging it from the power outlet for 30 seconds.
  • Press the 'SOURCE' 071218044349_22024.gif button to select the correct input source.
  • Check the connection cables.
  • Try the connected source with another TV.
  • Connect a different source on the same connection of your TV.

No picture but can hear volume


Try unplugging the TV cable from the mains and leave it off for a few hours. The longer you leave it disconnected from the mains ( i recommend overnight) the better the chance it will reset the TV.

When you switch the TV on, try pressing the SOURCE button until you get a picture from the cable/sat box or whatever connected to the TV.

If this fails you may have a problem with the power circuit board. This will cost approx £150 for parts and labour from you local TV repair man.

Good Luck

No Signal from cable setting.


check settings on your source...make sure you are not plugging into a DVI/HDMI port on your TV unless you are in fact converting from DVI to HDMI (there a connector to buy) if thats not it replace the cable with a different one. There are several varities of HDMI cable and the signal is faster as you increase in price normally. I have Monster cables that work Perfectly....I would also check TV settings on the port you are plugging into and try a different one to see if the result is the same. If the result is the same you may have a bad source. Always rule out the cable too.

Sony a/v reciever not sending video to tv.....


I don´t know if I´ve understood, but the best way to "pass" video signals to TV through receivers is using a stereo VCR, where you plug in any antenna. Then you connect VCR´s audio and video channels to the receiver. Turning on all equipment, select video1 source. You will hear sound through the system and watch video signal on TV. Hope this may help.
