Samsung dlp 50" light engine

Samsung just told me they wouldn't fix my tv because it was produced in Nov. of '06 and the only ones they would fix were made in August of '06 or earlier. I am way too angry right now to call the service tech number they so very nicely provided.

First thing is look at the model number of the TV and make sure of the complete model number. For instance there are 2 versions of this model requiring 2 digital board numbers. If your model is just HLR5067W the part number is BP94-1858A if the model is HLR5067WAX the part number is BP94-02084A. I bet yours will be the later of the 2 since that is a high failure version. They are NOT cross compatible. The parts you can purchase from Samsung at http://www.samsungparts.com

There are several things in this set that will cause this. I have ran into this problem 40-50 times on that specific unit. Most common problem is the lamp. Next most common problem is the DMD board which is a very expensive repair. Next most common cause is the ballast which powers the lamp. Next is the color wheel but usually that gets noisey before it fails. These DLP televisions aren't easy to diagnose but they're easy to work on. Now here's the thing, all four of these problems can be solved by replacing the light engine. If you are willing to put some money into it, the engine assembly is real easy to change. Just google the exact and complete model number and search prices of the light engine. I'm pretty sure the part number is BP96-00305J. Sometimes you can actually ship the engine from your tv in to be rebuilt. This can save you money. Any repair on this tv will probably cost 200-500 but they get a great picture. I have a samsung DLP in my livingroom. Good luck, Russmann.

although the lamp may look ok your tv has all the signs of lamp fail they only need a slight bang. I know that it is cheaper to replace lamp than light engine

When the tech said light engine what he ment was DMD board, the DMD board is the most important component on the light engine and most expensive, but still a lot cheaper then the entire light engine.

The DMD board can definetly, and often does cause intermitant errors. Your problem is absolutely not the Ballast, all the ballast is supply the power to turn on the lamp.

Your tech was right to go to the DMD board, the only other option that it could be is a digital board, you would have to see if it is doing this on all inputs.

Bad news.  Mine did the same thing.  Mine is the 61", but the internals are basically the same.  I replaced the lamp and the problem was fixed.  Then after a couple days, it died again.  I replaced the ballast, to no avail.  Took it to the certified repair center and they said I needed a new DLP Light Engine.  They wanted $1250 to fix it, but I was able to order one online from partstore.com for $700 and fixed it myself.  No problems since.
Your certified repair center will charge a minimal fee to diagnose and then you can fix it yourself if you choose.
The easist fixes for the lamp problems are A) replacing the bulb and B) replacing the ballast.  Anything else, you'll want a certified tech to diagnose the problem.

You have to activate the closed caption option on your charter cable box. Power off your cable box and immediately push the menu button. A menu should appear where you can toggle captioning on/off. Good luck!

I have alot of access to samsung DLP parts if you need anything. The other site where I am a repair tech has a great DLP training manual for the sanmsung DLP units if you want I will post a link cause they provide free tech support to help you diagnose and repair your set.

The unit has a defective light tunnel contained within the light engine. This part is not easily replaced and you will a qualified tech to replace it. Many service centers condemn the light engine at a much hight cost. Do not buy or let someone tell you the light engine must be replaced. This repair requires only the light tunnel.

You will need to have it diagnosed if you do not have the service manual, or the knowledge of how these circuits work. I can tell you to replace this or that but it would be a guess! You need to start measuring the voltages on the ballast circuit, as I have seen door switches, fan sensors, heat sensors cause all of your symptoms as well. Good Luck
