Question about Toshiba 32A33 32" TV

2 Answers

Toshiba CRT Hi - I have a 5 year old 36" Toshiba CRT wired up with surround sound. Not knowing what i was doing tried wiring my hi fi to the same speakers !! I seem to be hearing the laughs now. Turning up the sound on the hi fi, I heard a 'crack' noise from the tv and a 'electrical' smell. Now I cant get the surround sound from my tv. Have i blown the tv amplifier ? If so can i get a replacement and at what sort of cost ? Keith.

Re: Toshiba CRT

Hello krs001,
At best you have brunt out the audio power amplifier of your TV. At worst you have also taken out you power supply that is technically connected to every section in your TV. This right now, is not about replacing a part, it is about finding all of the damage that was done and repairing those items (you notice I said items). I say this because if you caught a break on this you will only have one damaged part and that is the final Audio amplification stage, but I don't believe in breaks or in luck so assume the worst. I would suggest that you take the TV to a repair shop for an estimate, if the estimate is over what you expect, get a new TV and try to repair this one as you look at your new TV. Its good for practice.
I hope this helps, Thank you, Shuttle83

Re: Toshiba CRT

Hi Keith,

Your Hi-Fi is designed to produce many watts of audio power. It would be a fair assumption that you took out the output section of the audio amplifier of the CRT.

The best way to accomplish sharing the speakers between the CRT and Hi-Fi would have been to use a switch box, that way both audio sources would be isolated from each other and whatever source was not being used would be put into a dummy load.

You need to find the Part number of the damaged part. If you open the CRT (power unplugged) you will probably be able to find it with your nose, since it was damaged and burned up.

Call MCM Electronics with the part number and see if they can cross reference a replacement for you.

Good Luck,
- Jim

I bought a 3 year old Sony FD Trinitron WEGA KV SW29M50 29 and it did not come with a manual question thereare 5 jacks above the video jacks what are they for i have surround sound speakers how do...

The inputs you refer to should be colored as follows.
(not necessarily in this order)
These are what are called Component Video inputs and is one of the way that HD capable equipment connect to your television. It will not get true HD picture but this input will provide you with a crisper clearer picture.

Good Luck and Happy New Year.....

Red light blinking no picture no sound

tart checking the cable connection to receiver, try moving or replacing cables.

If you have a surround with external speakers check surround connection cable and speakers wiring.

If the cables are OK, then the unit may be faulty.

In that case the fault can be either the audio board (often audio circuit is integrated on the main board) , or the sinput output signal board.
Also a contact on connection to internal speakers can give you same problem.

Who said it cannot be fixed? You can try and hook an external speaker to wires and test for sound. Maybe audio outs have sound?
