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.

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?
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.
the tv is fault, there is a lekage to ground, cause 5 amps is avery high current. plse take your tv to a w/shop and have the following checked
i rectifier diodes
ii power transistor, driver transistors, diodes, zener diodes
iii fusable resistors near the power transistor
iv making sure that a 90-110volts is getting out of the power supply to a line transistor, near the line trasformer.
the problem will be over
two things can be affected, a tuner if you were using out door
the other one is the power supply. the tv sensed a high voltage (surge)
firstly you need to repair a supply, check the following.
i rectifier diodes at the power supply
ii power trasistor, driver trasistors diodes, zener diodes
ii fusable resistor near a power transistor
after the tv will come on ----if they will be light on the tube then test a tuner, by putting in signal.
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
