sanschargrin,

I hate to be the bearer of bad news but your unit has some optical engine problems. Here is a web site which explains it all and tells you where to apply for class action compensation. http://sites.google.com/site/sonylcdrptvproblems/

Thanks for using FixYa and for the great rating.

TV cuts itself off


It may be overheating. Check the temperature with your hand by placing it over the fans/slots to feel for any excessive heat. If it won't turn back on until it cools, then it's a heat issue. You could help that out by using fans to circulate the air around the unit, trying to keep it cool by moving the hot air released from it and pulling in cooler air. Other than that, there may be a short somewhere, or maybe even a broken fan.

TV powers on, then cuts off by itself. After many on-off tries, tv goes to menu and through it, then cuts off.

Tv cuts off and green light flashes


Yup, it seems a lamp problem can give a blinking green light over the 10 times (1 - 10 times for diagnostic codes), but in my case rather than replace the bulb if it works for a minute then resets with the green light blinking, do what I did.
Take the lamp out and inspect it, it has breather screens top and bottom, if it cant breath because there clogged with dust, clean them, and you can remove the screens, use q-tips and clean the inside. I saved the cost of a lamp and it's working fine!

Pioneer sd532hd5/kuxc/ca powers down on its own


Could be a few things.First check your sleep timer.Sounds like a fail safe mode that when the tvs left on accidentally it shuts itself down so it wont overheat and die prematurely.The last resort is to remove the circuit board and carefully inspect the solder joints near the power supply with a magnifying glass and a bright light.Then resolder those.
