I'm a consumer (non-technician) and have had this Toshiba TV for a little over 4 years with absolutely no problems with it up until now. Yesterday (while watching the TV), the screen suddenly went blank and the power button on the front of the TV start flashing on and off. Pushing the button does nothing, and I tried unplugging it and then plugging it back in, but the flashing power button simply returns. I'm just trying to get an idea of what might be the source of the problem here and to get a rough estimate of what it might cost to repair it. If the cost will likely be more than $200, then I may just want to look into buying a new TV. Thanks in advance to anyone who can assist here...
This symptom is usually caused by a breakdown in the power-supply circuit. in most modern receivers (transistorised and/or ic), it may also be caused by a breakdown in the horizontal deflection circuits (horizontal oscillator, pre-drive or drive circuits.). this is because the supply volatages for the tuner, video intermidiate frequency(VIF), video amplifier, sound intermediate frequency(SIF) and vertical output circuit are usually supplied by the horizontal output circuit. since you are not inclined with this kind of job, better bring it to a qualified tv technician. with regards to the cost of repair, i cannot tell you the price since my location is different from yours. but to give you and idea, here in philippines $100 is enough for this kind of trouble!

Thanks so much for the help!
Before my TV went out, it had white flashes about 7 - 8 seconds apart - horizontal lines too.
I'm looking for a solution as well.
When I push the power button on the tv, it flashes to turn on but nothing comes up and the red power button light flashes over and over.
