I have a toshiba TP50F50/TP50F51 which has a red light on the front that just blinks. When you plug it in it makes a ticking noise as though the tubes are comming on, there is no picture/no sound. Just a little red light blinking.
Is this a dead set?

Hello,
Your TV must be at protect mode,try replace vertical IC &Horizontal output transistor.
I think this might help you.

Hi there,

Your TV's SMPS is doing a power cycling ie. It trys to power up & switch itself off due to component failure. Its doing it over & over again that's why u hear the ticking sound.

Could be HOT or SMPS problem... Vert problem unlikely to cause this symptom. Can be tricky & unsafe to fix if u don't have TV troubleshooting skills.

Hi there the common problème with the blinking red led is the convergence IC (2) p/n stk392-110 witch are quite large IC located on aluminum heat sink but after replacing these parts you may have to realign
convergence.

They've been waiting (patiently) all these many years for that solution.
