SOURCE: I am missing red color on my samsung 61" dlp tv

I bought this tv March of 2008, and Feb 2009 light engine went out, confirmed by TV repairman. Went through samsung directly.. WORST COMPANY EVER!!! No longer make this part, took 6 months to tell me that, after order went to 4 different repair companies. Finally, they offered $1770 to replace tv.. and weeks later, received a call that it was not approved so they offerred $1200. Still waiting for this check.. paid $2399 for this tv, still owe $1100!!! Samsung has worst customer service ever and do not stand behind their products. If you find replacement part for this tv, please post.. the part is expected to cost $850 and has to be professionally installed at $300.

I have a Samsung HLN437W DLP TV I turn it on and in about a minute there is no picture or sound and you have to turn it off you have to unplug it

That problem is usually have 2 causes..Its either power supply board or main board..

Please take this steps on how to determine the problem:
1. Open the back cover.
2. Check the power supply output...It should have 5vdc for the main board..12vdc or 16vdc for the audio and 24vdc for the back-light inverter..
3. If those 3 voltage supplies have encountered voltage drop...The problem could be on power supply board..
4. If the power supply output is normal..The problem could be on the main board...
5. If the problem is power supply you should check if the capacitors are bulged on the top and try to replaced it..If you can't do that you can purchased new power supply board..
6. If the problem is on main board there is no D.I.Y repair on that so you need to buy a new main board that fits to your TV..
Hope this solution will be helpful..

Thanks for using fixya...

My screen went black but I can still hear everything I removed the back panel and the lamp does come on but still no picture

If there is lamp ON and there is no picture at all, the DLP drive IC on the main board has damaged. Normally, damage to this IC will also couse to DLP [Digital Light Processor] also may get damaged. A thorough check to your Tv is needed. As it is DLP based one, proper care should be taken to repair this set. If DLP drive has damaged, it will be best o repalce the porcessor board as card basis. Anyway, keep in mind that the circuit for this tV is very complicated, such that even an expereinced service technician will also take time to pinpoint the exact fault point. A very high quality multimeter is needed to measure the voltages at the DLP board. Moreover experience is a must to do work with this TV. As far as lamp il ON, there is no fault to its power supply board. The fault lied in the main board itself. If you are aware in electronics, inform me. I'll assist you firther. Otherwise get this TV repaired by any experienced service parsonal or by the authorised service center for Samsung at your town. Authorised service center will have all sophisticated testing equipements ot do this service and it will be perfect in all respect. OK

Samsung DLP TV won't turn on

This sounds to me like one of two possibilities. First, check your ballast. If you're going through bulbs faster than you think you ought to be, you may have a ballast that is overloading. Its the 3" x 8" circuit board that connects directly to the bulb. They are plentiful and often cheap. Thats what I'd try first. If that doesnt' do it, I would invest in a new power supply board. That the board that the tv power cable hooks directly in to. This should give you a start, Comment back if you still need further help. Good luck.
