Tv not comeing on

Sounds like a Power Board / Video Board issue - stand by power is still ok - and why you have a red light - but the set is unable to power up the panel to drive a picture. Or the video board is the issue an is no longer processing the image to your panel. Based on the clicking noise - I lean towards the power board as the issue.

if just only clicking sound that was mean the cause either the regulator in the power supply is bad or the horizontal output transistor get damaged.

okay that clicking is from the relay switch..its just because either the micro chip,regulator horizontal output..or some other component in the power supply is not working..so your tv cant come on that is the reason you are hearing the clicking sound.you need to take your tv to a tech so that it can be repaired.good luck.

BAD FAN MOTOR.......OR FAN SWITCH

Replace capacitors in power supply you will see that they are bulged on top

that is a indication that a fault is about to occur, dont force that tv take it to a technician before it switches off completely, a power supply is supposed to be checked.

clicking = power supply not coming up
bad power supply, or bad (shorted) part causing power supply to not come up
with a volt meter we can troubleshoot

Most likly it is a problem in the power supply regulator circuit. pretty common for Toshiba TV sets. If you know about TV serviceing, first thing to replace would be the regulator IC as that is the problem 80% of the time. if that does not help then you will need a schematic to trace out the regulator circuit. Good Luck PS please dont forget to rate this thread.
