Make sure the set is unplugged, find the screws for the cover nearest the electric input cord. You will need to take a look at the power supply that it plugs in to and all the wires coming out of the power supply. make sure you are still comfortable with this job. If you feel you are, then we will need to get a part number and see how much the part will cost. While you have the set open make sure you look carefully at the inside of the television to make sure nothing appears to be burned or damaged. Let me know when you get this far. Remember, we are not responsible for any damage you do to your own tv. Please be careful.

My tv cuts off after 5 minutes

Could be the power supply overheating and going into protection mode. If it is under warranty use it. If not then you could take it apart (this will void warranty) and check for swolen or leaking capacitors on the power supply.

Hi Brenda,
This kind of symptoms is an indication of faulty sustain boards inside. The unit must take apart and need to troubleshoot the boards to determine where the fault came from.
Yes this is fixable but needs to check by a qualified TV technician. Since it is only a few months old, this is under warranty period, avail it because the manufacturer will fix it for free. Don't attempt to open the back cover because it will void the warranty.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

This is so retarded I have written whats wrong 8000 times and all I get is bs!!! The flippen disc wont eject on my 2 mnth old dp26670 tv/dvd combo. What is wrong???????

I am not sure what others have told you, but I can only guess as they did. There can be many issues that can cause this and without having it in my hands I can only guess.
It could be a bad ejector motor that activated the eject mechanism, a bad mother board that does not tell the system to eject the disc, or something could be physically jammed in the unit! A belt to the mechanism could have come off as well. The eject button may not be working. If this is only 2 months old, why havent you contacted the place of purchase or at least the manufacture for warranty on this. If you take it apart and attempt a repair, then this will void any warranty you have.
I can only suggest you do a reset on the set and its memory. Unplug the unit and let it set for several hours, maybe over night and the plug it back in and see if there was something in the memory locking up the player. If this does not work, then you can take it in for warranty work, or get back with us on how to take it apart and look for causes.

While watching tv on my 2 day old Samsung 46c650 the picture went black. Audio was still playing.

If it's only 2 days old then take it back to the store where you got it while it's still under warranty.

It is most likely a loose connection inside the tv, or a bad component on the power supply or inverter circuit board.

But, if you take it apart to check, then you will void your warranty.

Return it right away and get a new one.

Good luck and please comment back if this was helpful.

Vizio with terrible color

YES. Take it back. Also take your DVD and cables also. Have the store try the tv with their DVD and cables and see if you get the same problems. It it good, then try your cables. Or try your DVD with their cable. It's under warranty now so resolved it now. If you bought by credit card, that may have a brief warranty also.

Password lock unknown

If everything works fine and you're able to change settings (picture, sound etc.) why do you want to go into the lock setting? That's the service menu. The manufacture put it there for a reason and only qualified techs with the proper equipment should be in there. Also know if you decide to start typing in random numbers you run the risk of locking your tv and voiding any warranty you may or may not have.

How do you repair the or check the Back lamp?

This is not something you should do yourself unless you are experienced at doing this type of service.

If you call the parts supplier for the manufacture of your set, you have to find out the part numbers for the backpane lamp and power supply for them.

Some sets use 2 sets of lamps and power supplies together, or a common supply for multiple lamps. This is model and design dependent.

In some models the lamps are not able to be replaced. They replace the complete screen assembly.

In some models of screens, the complete screen assembly must be taken apart like a wafer system. Taking the screen apart is not too bad. It is getting it back together, and having the lamps installed to not give shading errors.

You will most likely have to undo a number of ribbon cables. If the cables are heat sealed to the circuit board, they will have to be replaced, and re-sealed back on. If the ribbon cables are on connectors, then this will be easier.

My suggestion is to give the set to the Philips service rep to evaluate and replace the lamp system if it is feasible or able to be done. If they make an error or accidentally damage something, they will be responsible. When they do the work they should warranty their job.
