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.

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.

2 tv's when I try to cut them on they make a clicking noise

The TV is on protect mode. The clicking sound is the protection switch that keep turning the TV off to prevent further damage, this happens when a fault had been detected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.

If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

If you want to DIY you find parts here, a common fault is PSU, but part must be tested before replacement.

My Toshiba 27A62 Tv keeps clicking on and off, but the set won't turn on it just keeps clicking on and off. Help!?

When working with my Toshiba 27A62 TV with the same problem, we found that if we replaced the capacitor C520 on the main board it fixed that problem. It was a 25V 470uF cap located in the middle more towards the front 3rd of the board.

TV won't turn on immediately

Right now it should not be expensive to repair,the symptoms point to loose solder conection and it has gradually become worst,if you take the set to the shop it should cost less.What happens is the 10 legs the vertical ic has get overheated and loose,to prove this tap on the side of the set just to see if it reacts,it should also be check for other overheated areas while in service.If the quality of the picture is good then is worh repairing.
