Question about Toshiba 27A62 27" TV

1 Answer

Toshiba 27A62 My Toshiba 27a62 will not cut on. It makes this clicking noise like it is trying to cut on,but never does. The TV is only 3yrs old. It order for it to work we have to unplug it for a couple of days, and then hopefully it'll cut on. What could be the cause of this? Is it something I can do myself? How much would it cost to have an expert work on it? Thanks

I do not know, but several people have said that Toshiba TVs make a clicking noise on switch on, this could be a relay, and not arcing. A power up circuit operates the relay. So two things could be going wrong. 1) The power up circuit input voltage is too low or weak to fully operate the relay, so the contacts do not close. Probably a faulty electrolytic capacitor. 2) The relay has bad contacts. Relays have become so miniature that you will probably find it is only slightly larger than an integrated circuit, and soldered on the circuit board. The long rest may allow a bad connection to oxidise due to dampness, and so conduct more, or allow a capacitor to recover some lost capacitance. If you know these parts of the circuit, you need a normal digital meter and a capacitance meter.

My TV keeps switching its self off, it makes a clicking noise as if its trying to switch on. Then cuts out.

Do to the clicking noise your tv makes is a very common idicator that your power supply in the tv is failing. Its an easy fix lots of DIY videos on youtube but may cost you a arm.

My tv keeps saying stand bye and it won't cut on all its doing is making the click noise and the red light keep blinking

Try unplugging it for 30 seconds and see if it resets. If not, take the model # and get on the internet for the manual and go to trouble shooting page. It should answer your questions

That model is an LCD that uses a backlight. Probably with CCFL tubes. They are known to have bad inverter supplies. Its an old TV though. Keep that in mind.

Our samsung le40r87bd is making a strange clicking noise wont come on can u help its about 3yrs old and has not given us any trouble before this!

The clicking sound is coming from the regulator in the power supply. It is trying to turn itself on, notices that the voltages are not correct and turns itself off to protect the rest of the TV and repeats. You need to replace the power supply.

Display IC seems to have gone. It will be a replaceable module. Only you have to figure out which one it is. Such thing happen in electronics. Look for any burnt or bulged IC.
