Re: toshiba model tp5581a
The problem lies within the unit.
You have a hardware failure within the board. Most likely the power supply board needs to be repaired or replaced. I hate to give you this bad news, but the cost to have the power supply board repair or replace will exceed the value of your rear projection television. Of course it all depends how much you want to invest in the television. Sorry, but I wish I had good news for you. Just being honest.

Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast. It's major symptoms are clicking,electrical sounds,shuts off and on and get the lamp indicator.But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs,It's major symptoms are clicking,electrical sounds,shuts off and on and get the lamp indicator, it could be time to replace the lamp.The lamp you need is XL2100 you can find it here: http://www.discount-merchant.com/Sony-XL-2100U-TV-Lamp-p/sony_xl-2100u_replacement_lamp.htm?Click=48173.Have a blessed one!
It sounds like your lamp is getting close to the end of its lifespan.The lamp is what gives your screen its brightness.With time they start losing this brightness.If you were to wait to replace it till it goes out completely you would have a black screen.You can purchase a quality lamp at discount-merchant.com
If the relay clicks you most likely have a leaky diode or bad transistor in the stand by or start up circuit. There is a manual available for that model called. Toshiba Power Supply and Shutdown circuit Troubleshooter. Its available at the following link. It gives step by step instructions so you can figure out exactly whats wrong with your set. The site emails it too you after you place your order and they also provide free unlimited tech support so you will have a resource for help if you need it. I am one of their on line support techs. I highly reccomend that Manual to any one with a toshiba that will not power up. Here is the link. http://servicemanuals.vstore.ca/
I have the same thing going on with mine. What it is the SLR main Reg. is bad. The only way you can fix it is you can't put just one part in it you have to replace one of the boards. When you open the back panel up you will see three boards in a roll the one that needs replacing is the power board you have to get the model number. My Tv is a 65 HD model 65h81 the board on mine has a part number of PD 7400 yours will have something like that. Well let me know how it's goes my E-Mail is firstname.lastname@example.org
