Question about Mitsubishi WS-55819 55" Rear Projection Television

1 Answer

HD Problem When watching HD programming sometimes notice a ripple in the screen the rolls through out the picture. Sometimes the picture is so clear that you can't notice it. Tested a newer HDTV on the same Directv HD reciever. No ripple at all. I only am noticing the ripple when watching HD. It is hooked up through the component video connection. Even when watching the HD channnels off my digital antenna, I notice the ripple effect on my screen. It is like there is some interference coming through. It is a minor distraction, but want to know if something needs to be fixed at some point.

    I just had the caps replaced a couple of weeks ago. Works great now.

    try connecting a dvd player to the same componant input and see if the ripple is still there. I suspect it will be. The 'formatter' module is suspect, or a bad regulator on the 'signal pcb'. Yes, this will eventually require repair.

Hi I pressed the wrong button turning the TV on, now I have no sound and can't get it back. please help.


Hi,

SAP (Second Audio Program) may be turned on. This used to be a widespread RCA problem maybe caused by incorrect conversion of analog signals for viewing as phony HD images. Costly class action lawsuits addressed the problem in USA. Most of the specific equipment causing the problem used by broadcast/production/satellite industries was either adjusted correctly or replaced. If the problem re-occurs, it may caused by specific TV channels or programs that you watch. Codes inserted in the signal are incorrect and confusing the RCA TV Guide and audio processing circuits. The error causes SAP to be incorrectly selected as default for all channels.

Remedies:

Change audio settings in customer adjust menu to Stereo from SAP. Sometimes the On screen TV Guide set-up must be cleared of location, etc., and set-up again.

Sometimes it is difficult to set correctly. Unplug TV for 12-24 hours and TV may reset to default stereo setting instead of SAP.

This was an active Class Action legal issue 10-15 years ago in the USA.

I just hooked up my new Samsung 55" LED LCD TV it has 1920 X 1080 resolution and 240Hz speed. Initially the picture quality was fantastic, sharp clear great colors...almost jumped off the screen at you....


Try the Direct TV connected to the TV via component cables and see if the picture is clear and stable at the same time. If it is normal check the Samsung website for support on your model of TV to see if there are ANY known issues and or software updates. Please take a moment to rate my answer. Thanks..

You will need to contact a Mitsubishi Authorized repair facility. The entire electronics package must be removed and sent back in to Mitsubishi. The problem is the Formatter circuit board which is no longer available as a replacement part. The repair cost is very expensive and must be quoted by the facility you contact not me. Expect 4-6 weeks turnaround.

The picture rolls vertically sometimes.


I would check the capacitors in the verticle deflection circuit. Also try resoldering the verticle output as well as the verticle yoke pins where they connect to the chassis. Mitsubishi has had some trouble with their capacitors, you may have one that is leaking. Let me know if I can help you further.
