Mitsubishi HDTV Help

Archived from groups: alt.tv.tech.hdtv (More info?)

I have a 5 year old Mits HD model number WS55807. Recently I have had
some reception problems and had them fixed. Now when I change the input
to show 1080i, I get what looks like a horizontal hold problem. When I
look in setup I am only able to show RGB, I can't get the YPrPb to
show. I have had a local TV repair guy try to attemp but no idea as of
yet. Does anyone have any ideas as to what might be causing this. I
have tried numerous wiring combination to no avail.

Be more specific and someone might be able to help. What kind of reception
problems and what was done to fix? How does that relate to this problem?
What source are you using? Setup menu in what device, the TV? Does the set
give a display that indicates it is in 1080i mode?

What do you mean by the statement "In HD Mode I am not able to set to YPrPb
only RGB?"

It sounds like your cable box is set to something other than 1080i. The
tech who repaired the set may have set the option menu to force the DTV
input to 1080i to adjust the convergence and did not set it back to auto.
Press MENU then the sequence 8,7,2,0. Set the DTV port to auto, hit menu to
exit.

Leonard, thanks for the input. I was able to perform the above,
although the sequence was 8,2,7,0. It was set to 1080i. It fixed the
Horizontal hold problem. Now I can't get any audio or video when
changing the input to HD and going to the HD channels. Everthing else
is working fine.

Thanks in advance,
Jim

Try re-initializing the set. Sometimes the microprocessor register gets
trashed and it doesn't know how to talk to the other serial controlled chips
in the set. The (SONY) chip that switches inputs is one of those that I've
seen have problems.

I have a Mitsubishi WS-55859. I cannot turn the tv on and the green flashing light will not stop flashing
