As soon as I turn my tv on, the light turns green and it acts like it is coming on. Then it turns right back off. it will do this several times before it will come on.

Seems to happen more when the tv is cold.

The capicitors could be failing on your power board. Have look at the power board and see if any are bulging at the top.

We have a Philips 4 BDS4231R/00 and it does not start. We can here the relay sound and if we turn it on and off say 7 - 10 times it works fine. Could anybody tell me how this can be fixed. Please


Hey John, I am experiencing a very similar problem. If I unplug the TV when it is on (green light) and plug it back in. It begins green, and clicks to red. I immediately turn the TV back on with the remote. Most of the time it seems to struggle for several seconds, sometimes with a little scratchy audio popping in and out. It will then go from green to red on the TV and if I try to turn it back on it will go green for a few seconds and back to red but without any click coming from the TV. No matter how many times I try after that, no TV. If, on the other hand, I unplug while green, plug it back in and with the remote turn it back on after it has come up green and then clicked to red, it will come on. It might take thee or five times but at least it comes on... If you hear of a real solution, please let me know (bennettkw@hotmail.com) in the meantime, best of luck.

Mitsubishi DLP overheating


Mitsubishi has problems with the thermal sensor going bad. They extended the warranty for several sets. The sensor is right by the lamp. Call mitsubishi and insist they do something for you. If you keep playing your set, the bulb could also be at risk. I would think your set is covered being a 62" set. Good-luck and be sure to act ASAP.

Right out of the box. doesnt work


Don't feel bad - these are cheap TV's and there are lots of problems with them. Just be glad it failed so soon that you can take it right back and get something more name brand this time.
Remember - always google the model number you are looking to buy (with either "repair" or "complaint" in the search) and you'll be less likely to buy an TV industry land mine.
