Mitsubishi WS-55315 no video present

I have a Mitsubishi WS-55315 Rear Projection TV audio is present but video is not. I have tried tapping on the side of it that didn't solve the problem. Also tried unplugging it for over an hour and that didn't correct the problem either. How or what can I do to try correcting this problem? ( The menu shows up fine but when I try to watch a tv show it is not showing a picture I can only hear the audio)

Hi,

Appreciate the direct "Ask Me".

You description of "...no video but with audio..." could indicate a number of possibilities:

  • power supply section;
  • tuner
  • video amplifier/selector;
  • vertical section;
  • horizontal section .
Other ideas are:
  • Since it has still sound, then the power supply is a least likely possibility;
  • Since it has still sound, then the tuner is a secondary suspect;
  • Since the menu shows, then the vertical and horizontal would be highly unlikely.
  • which eaves us the video amplifier or electronic/soft selector as the most likely culprit.
Further diagnosis would of course would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

Ws-55315, screen turned to fuzz


If it was the lamp there should be nothing. press the menu button if the menu does not come up the issue is with the tv. If the menu does come up try a second source a dvd player or game system. If the issue is only with the original source than the original source needs to be replaced.

Mitsubishi WS-55315 audio no picture


Good Day;

More than likely your TV has "COOLANT" (ethylene glycol) on the circuit boards. This fluid comes from the CRT's (picture tube) this fluid is used to keep the CRT's cool, such the name. This fluid from the CRT's leak when TV is on for long periods of time, the chamber expands and the seals leak.

One can remove this fluid by using "acetone" & small brush. The fluid is hard to see, use bright light, they spots can be smaller then a DIME. Also, the fluid can corrode the parts and traces on the boards. To protect the TV in future place heavy plastic or thick cardboard over affective area, make sure TV has proper air flow around TV.

If after the fluid has been removed and TV still does not work, call an Authorized Service Center to come out and repair TV after giving you an Written Estimate. The boards are not available.

Always try resetting the TV by unplugging it for one minute then plug back into A/C outlet and ALWAYS UNPLUG TV BEFORE ATTEMPTING ANY REPAIR ON THE TV.

Good Luck, big IRISH.

Audio but no picture


Try first unplugging the tv for one hour,
you can also try also a whack test, tapping gently the TV on the side , if you get picture then it is a wiring or a bad connection.

If you have no picture it can be the lamp, if the lamp is fine is either an internal board or the light engine, but this is uncommon.


here you can buy replacements.

If you need a technician call the number listed on the owner manual.

Pink horizontal line when the tv is powered on.


1. White raster with no signal, washed out looking video with signal. Access the service menu, "menu 0357" use the audio button to select "video chroma" adjustments, use the video button to select item "40 - AGIW", use the adjust button to change the setting to 0, then press the enter button to store the change.
