    My samsung tv tx-t2782 played fine all day today and then the tv just shut off by itself. When I turned the tv back on, the entire picture was wavy. Now it only stays on for 10 seconds and then it will shut off by itself. The red light will not come back on unless I unplug the tv and then plug it in again. What could be the problem? I bought this tv 8 months ago!

    We have the same TV and this has happened twice. The first time, the authorized Samsung TV service center replaced the entire inner workings of the set. The second time we called the repairman directly and we were told this is a chronic condition for this model - evidently Samsung has had so much trouble with this model they are no longer repairing the sets; instead, they will provide a brand new TV to anyone who has owned this model for less than 18 months. In short, Samsung made a real piece of ****!

    I was told by my repairman that the motherboard was bad.And is on backorder,6 to 8 weeks. They are in the process of replacing it through SAMSUNG. Apparently this model is a LEMON! I am glad I have a 5yr. warranty,finally it paid for itself. I am always leary of buying extended warranties, it seams like gamble. In this case it was worth it !!!!

Tv turns itself on and off

in general terms it means the microprocessor in the set is locked up, you have indicated a Samsung part number but NOT a brand and model number and those are needed to know if help can be given or not.

Sounds to me like the lamp may have failed on this LCD projection tv, You may have heard a pop from the tv. if so the lamp is gone. On the side where the lamp installs you will find a lamp code # orange tag. This BP96-***** is the lamp #. Ebay that number with niosales. Best pricing, free shipping excellent quality lamps assemblies.

I just fixed this very same problem. The capacitors are the problem. However, I think that if you have some minimal skills with soldering, you can fix this yourself. You just need to take out the system board, then the power supply parts are on the top right. The bad capacitor(s) will be bulging at the top and possibly have some brown stuff coming out. The ones that go bad are 1000microfarad, 10V, however you can replace them with higher voltage. I got 35V caps from radio shack for 1.59 each. You just need to solder out the bad ones and then put the new ones in and solder. Remember that the negative end goes on the side with the bold black part of the circle on the system board. Then just cut off the extra ends of the capacitors. If you are capable of doing this yourself, you will spend at most 6 dollars instead of however much a technician costs.

TV shuts off after 10-15 min.

Look through your owners manual for timers, and if the tv continues to shut off..... then there's a problem brewing in your power supply section and associated circuits......

I don't recommend working on the TV unless you have some experience and knowledge relating to the safety issues and electronic repair. Most rookies will not successfully complete the repair and probably do more harm than good.

Sometimes when the convergence chips fail, the TV senses the changed load condition and shuts down.

Unplugging the blue, red or green convergence connector on the convergence board removes the overload condition if the IC is shorted and allows the tv to run, with one color missing.

This is done with the tv unplugged. Then plugged in and turned on to see if it starts. Turn off immediately if you here it start.

Now you know if convergence failure caused the shutdown. You can repair the convergence circuit if that is the problem.

If this has no affect, then you could have a number of different faults in Vertical output, Power Supply or HV circuits that require the expertise of a qualified service person. This would be a bench repair in most shops.

If you live around Calgary, Alberta try me instead:

Or try to the find the repairperson part of this website (on the Homepage) and search postal code. Maybe you will be lucky and someone from your area is listed for Projection TV repair.

Most rookies doing this job will cause damage and not be successful. They will pay double for someone to fix their mess or end up scrapping the TV. It is not a simple task. It is more difficult than batteries on a remote.

Good Luck
