Samsung DLP HLP5663WX/XAA

[Eric]

This DLP TV has a beautiful picture when it works properly. At first
the picture would get distorted and ghosting would appear, the color
was wrong etc. I never heard any buzzing but all indications was the
color wheel was failing. I purchased a new color wheel from Samsung's
Parts Store. I replaced the color wheel , vacuumed some dust out from
the back of the set. When I turned the unit on, the picture had a blue
tint. I remembered reading about the possibility of this occurring and
pulled the jumper . After powering the unit, the picture was beautiful
like new....for about 7 minutes when the lights on the front panel
indicated a lamp failure. THe lamp was only a few months old but I
happened to have had a new ballast on hand so I replaced the ballast.
This didnt solve the problem of the unit . I purchased a new Phillips
lamp from Discount Merchant, installed the new lamp and re-set the
lamp hours from the service menu. Now I have intermittant picture issues.
At times the picture will have hot spots.
At times the unit will not power up after the automatic 3 attempts.
I'll have to unplug the unit for a few hours. Other times I can watch
the set for several hours (12 hours or more) without incident. Also,
the remote control always displays a red light when in TV mode and a
green light in any other mode. The remote will not always operate the
TV. Your thoughts?
