Toshiba CX32D60 Problem

When I turn the TV on, it immediately shuts off. I used to be able to fix the problem by unplugging the unit for a while, then plugging it back in. That doesn't even work now. Is it the switch or wiring? Someone suggested it may be some sort of tube issue?

Not a tube issue...........It is going into shutdown mode...

1) Pull chassis...solder any /all bad connects in horiz,vert,power
circuits....look for evidence of over-heating....

2)Check for weak electrolytic capacitor in horiz driver circuit..use ESR meter..................................................T.

Re: Toshiba CX32D60 Problem

Fix this exact TV today with the same symptoms of shutting off immediately when it comes on for a split second. Removing the cover showed a filter capacitor that showed it had excessive heat on it for some time as the plastic wrapper is recessed from the top. Unfortunalte I forgot to write down the
capacitor designator but it is hard to miss as it is relatively big about 2 inches tall and has a diameter
of around 1 inch. The value of the capacitor is 330uF, 160V. It is near the control IC801.
It is also a good idea to replace C863 (4.7uF, 50V) a startup capacitor as someone else already
suggested since you are already have the unit open.
I replaced the 330uF, 160V cap with one that is 470uF, 200V of the same size. This TV was manufactured in 1994 so it is understandable this cap has reduced in value and has its ESR
parameter increased due to the high ripple current. Replacement of this cap should give you yet
another 10 years of service unless something is broken with it.

Check the capacitor C863 (4.7MF-50V) that is located in the start up circuit and it is connected to pin 2 of IC Q801.

I have a Toshiba TV model 36A43 that won't power on. The same thing happened yeaterday as this morning. The tv will not power on via remote, or the manual power button. Yesterday, the same thing occurred...

It sounds like you have a switch problem at the front panel of the set. If a switch gets stuck internally the micro is trying to process the command and won't respond to any other commands. The only way to find out is to go into the set and desolder all the manual switches and see if the remote will work the set. It has a seperate detector for the remote. Thanks for using fixya. Good luck

Will not turn on. Shuts off immediately after turning on.

Sounds like the vetical deflection went out. Most likely have a leaking picture tube and the cooling fluid has goton on the board so you would be beter to replace if that is it.

No color when turned on, after a while it color returns.

This is a cold solder joint in the signal section of the set. After it heats up, that problem area conducts better. Have an experienced electronic person reflow some solder on the board.

On/off switch Toshiba model CX32D60

what i have done in the past is use one of the other buttons, if it's a push switch what ive done is hard soldered and then use a wall switch to turn it off.
