Blinking led

You likely have bad convergence output IC's that have caused one of the supply fuses to blow. This repair will have to be performed by a qualified technician. If you were in our area and has us repair this the total cost of the repair would be about $340 if I am correct about the cause of your problem.

The key to this repair is "intermittant convergence issues".
1) Locate convergence amps ( large IC's mounted on large heatsinks.) On PCB in back.
2)Remove circuit board
3)solder any/all bad connects
4) reassemble - test run
Note:Fuses are not an issue at this time.
Note:Convergence amp IC's should be replaced for durable,
long-lasting repair.

Not an easy fix....requires chassis pull, careful soldering and
replacement of parts and fuses.....would you like step-by-step?

It could be the lamp went out and needs replacement. The Toshiba website states when this happens to unplug the televison for 10 minutes then plug back in. If that does not work then try another power outlet. If that does not work then call for service
