Samsung DLP - Model HLR4667WAX/XAA

Your lamp is burnt definitely (lamp makes that sound ,take lamp out and You will see inside lamp) no sound ,because unit goes to protect mode and shouts down power

It could be you color wheel try to go bad, however when it does you will lose the picture. If you can repair or fix a computer you can change your color wheel if it goes. Cost Appox $100 you can search by your TV model #

Good Luck!

It might be the dmd board. You may be able to call samsung tech support and they may be able to diagnose over the phone. Good luck.

Failing DMD board or it is also possible it has bad ribbon cables

It is likely the color wheel motor making noise

This TV is horrible. I have the same one and not even a year replaced the light bulb twice. Very disappointing for a Samsung.

check your uhp lamp.

IT'S YOUR DMD MODULE IT'S PART OF LIGHT ENGINE IN THIS PATICULAR MODEL WHEN THAT GOES BAD YOU HAVE TO REPLACE WHOLE LIGHT ENGINE CONTACT DISCOUNT MERCHANT OR RIVER VALLEY ELECTRONICS THEY HAVE THEN FOR PRETTY CHEAP.

This is a possible fault in the power supply, and can be a problem with some decoupler caps on some of the boards. The vertical bars and unstability are usually attributed to having high frequency noise and or clocking pulses crosstalking on to the power distribution lines that run through the boards. This can be switching power supply noise, or cross-talk from clocking pulses.

Another thing that can cause your described fault is unstable clocking between the devices that are reading and writing to the data busses. There are a number of data busses running through the set for the boards to be able to communicate with each other.

The tech will use the process of board swapping to service the set, and then do the adjustments as necessary to make sure the new boards match up.

Yes... DLP sets are fairly expensive to service!

This is my personal opinion. If the set is out of warranty, I would change for a Plasma or LCD set. If you compare the performance of these to ther DLP, the difference is very big. From what I am seeing from a service point of view, the DLP's are lower in reliability.
