Question about Televison & Video

Toshiba TV Mod. 32D60 will only turn on by disconecting and re conecting power supply many times. Light on switch flashes each time but instantly goes off until finally TV turns on. Is this a swirtch problem or more serious. Set is 14 years old but is otherwise perfect.

    The solutions you have offered is really of no help as they are quite obvious.

    What I am anxious to know is if the switch is the problem, then is a new switch available and if so would I be capable of installing it. I have opened the TV back and observed the switch is held by 2 screws easily accessable and with 4 wires attached. As an alternative can the wires be crossed and the switch bypassed as I would be content to turn the set on and off manually.

    Thanks for your help.

    If it is the switch, can the switch be bypassed by crossing wires. If not, is new switch available. The previous suggestion I received to check power cord or switch is of no help as these ckecks are the obvious.I will appreciate your help. Thanks

Hi and welcome to FixYa,

With the indulgence of the others...
Being a 14 yr old unit, then it could still be using a hard switch and not a soft switch. A hard switch is electro-mechanical similar to plain wall switch of a room lamp/light. A soft switch is like the key/button of your mobile phone. A soft switch only requires a momentary contact but would continuously be activated until triggered off. The actual switching is done by another component.

Having said the above, then the decision to hardwire a jumper or even installing a remote/external switch would depend whether the TV's existing switch is a hard switch or a soft switch. If it is a hard switch, then yes, it is possible.

Another indicator that it is a hard switch is the presence of a spring and a latching mechanism. Incidentally, your description of 4 wires makes me think that it is a hard switch. If you could determine that the two of the 4 goes to the AC cord/powerline, then it would be a two-way hard switch.

Good luck and Thank you for using FixYa. Happy Holidays.

Hi 
There will be an electronic  problem somewhere in the set that is preventing the power supply from powering up. It may even be the supply itself . 14 years is getting on for this type of set. I do not think it would be worth pursuing

    There are some things you can do to isolate the problem. There is a trick we do in the workshop to determine if the power supply capacitors are failing, we heat up the power supply area with a hairdryer to raise the temperature to the point where things will fire up. If the set can run with things warmed up, then it is a fair bet that the supply will need to be reconditioned, mostly replacing capacitors. There can be other power sections of the set that may be affected the same way. The real outlook when things get to this point  is that the set may be getting a little too old to continue in service. Happy to answer any questions you may have.

    Hi again.I understand that because you are operating the switch,you are perhaps relating it to being the problematic part in the set. I do not suspect the switch.  I have repaired a lot of TV's over the years, and modern sets using SMPS type power supplies that are generally turned on and off by remote control do not tend to have "switch" failures. It is kind of like suggesting(to use another example) that "the car wont start, then it must be the keyswitch causing the problem".  You can replace the switch if you want, would be easier to test its function first.  Bridging out the contacts would tell you if that was causing the problem, or using a volt meter to check for primary DC  supply across the rectifier. Should be in the area of 150 volts for USA, and 300 v the rest of the world.   Be careful here. MAINS VOLTAGE CAN KILL YOU. Be sure to disconnect the power before you do any work. Be aware also that the power supply may still have charged components in the rectifier stages that can give you a nasty boot also. 
    Let me know how you get on doing this.

It is not a superficial problem, if the TV keep going in protect mode after unplugging power cord, that means that there is an internal fault, and must be repaired.

Posted on Dec 19, 2008

    Ginko Dec 19, 2008

    This happens because The TV set detects an internal fault, like a blown capacitor, broken solder joint, or bad voltage or any bad component inside, and will activate protect mode, that will prevent TV from starting.

    If the TV starts after unplugging power cord many times the problem is likely to be the PSU board, to find out, the parts must be inspected by a technician.
    However, if the TV is nearly 15 years old , it may be getting to the end of its service life, and may be wise buying a new tv.

    A thing that you can do at home is leaving the TV unplugged overnight, and see if this improves the situation, by draining power completely, if not, replace the TV.

Why won't it turn on?


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

The TV will not turn on. When the switch at the lower left corner is pressed the light in the switch flashs green for about 4 seconds as the TV seems to go through a start up procedure. Then the light...


The red flashing light is the service code. My guess is the power supply is bad now, but it could be something else. If the TV is under warranty, take it in and get if fixed. If it is not, then you may try to check the power supply first. Count the flashes of the red light and check online for the issues when this model flashes, 4 times or 6 times... or 9 times, etc.

Good luck!

Toshiba TV Mod. TV32D60


The problem is not likely to be a switch. I believe that your set has what is called a "switch mode" power supply. This requires oscillation to occur. The oscillation is started by a capacitor circuit. If the cap becomes defective, the oscillation may not start and thus the TV won't come on. Unfortunately this is not a set with which I am intimately familiar so I can not tell you what part to replace. This should be a simple repair however. Check around at a few service shops to see if you can have it examined without a large expense. In the meantime, I'll see if I can find a service manual for it.

One other thing you can try (fi you can solder) is to look for poor solder joints on the main board. If some exist, they can change the circuit characteristics enough to cause what you are seeing. Look for and resolder any joints that appear to be grainy or have rings.


Keep me posted.

TV LED Flashes then TV shuts itself off


capacitor problems in power supply or a regulater isolate the power suppley by disconecting the line output stage/unplug scan coils for example and run a 60w bulb as a dummy load one wire to earth and the other to rail voltage colecter of line output transister if the bulb glows steady the power supplys fine

TV is not powering up and red light keeps flashing


I had the same red blinking led problem on my Toshiba Theaterview tv. I resolved by:
- Unplugging the tv.
- Press several times (3 or 4 times) the tv Power button.
- Plug the tv back in and press the Power button once to turn the tv on....tv worked!!!

I've had the problem before and tried unplugging the tv for a couple of days and that had also worked, but I this recent solution seems to be faster.
Good luck!
