Power light blinking mean that the internal power supply is not working correctly. Often the internal power supply itself need to be repaired ( usually a one hour work if spare parts available).
Another basic circuit in the TV can be short circuited due to a component failure and consequently cause the internal power supply to block everything.
A routined pro must be able to tell you within short time cost of repair and spare parts. Up to you to then decide wether or not have this set repaired. Be aware a pro will ask you a fee for this service, even you don't want the set to be repaired.You can save some cost if you bring your TV set yourself to the repair-shop.
The kind of problem is not really age-related; if your TV is running daily 16 hours, with many on/off switching, and particularly in a cool place can degrade some components within warranty time.

VIZIO flickering Tv screen easy fix( no money ) .... I left town unplugged the Tv. When I came home home ...
sounds like somebody set the timer. normally this only makes the set enter standby mode and pressing the power button or a channel button usually wakes the set normally.
Just a longshot but have you tried pressing 09 while the light is blinking?
Ballast Board! Go to Encompass Parts Distr online find out what your Part# is! or Call 1-800-638-3328 also try UED 1-800-648-6657 This TV has alot of fuses over 20 of them!You didnt say have you replaced Lamp thats what goes first 9/10 unless you get power surge or Bad capacitors on the power supply Board caps are bad if they are puffed up on top 1000uf25v caps!
I had a similar problem, except I could make the screen and sound come back by banging on the the TV. I opened the TV and poked around on the circuit card and found a loose pin on one of the regulators, labeled C3852. I resoldered the pins and its working fine now.
If you are getting static on screen you dont necessarily rule out the FBT, but if there is a fusible resistor by the FBT that is blowing it may be supplying current to the vert IC, the IC may be shorted internally or externally, check your connections and try replacing IC. Also check the pump up cap and if it is powered off the FBT the rectifier diode.
if you have not gotten this fixed get it to a repair shop your problem is intermittent there might be lose solders or component in the power supply is failing and needs to be replaced.good luck blessing from belize
We had the same problem, for the same model of Toshiba TV. Had it repaired yesterday. Turns out the problem was the power supply (P.C.B).
The total cost was $192.66 Canadian funds (taxes and labour all in). Our model was 6 years old, buts its playing like a brand new unit now. Hope this helped ...... Good luck
