Hello,
The Horizontal Output transistor needs to be changed as it is most likely shorted. The current transistor on this set is a 2SD3402 (no longer available) it's new replacement part number is the 2SC5902.
Order 2 2SC5902 Horiz Output transistors.Replace the transistor by it self once and if all is ok then fine.
If not replace it again and also the the Flyback HV transformer. The HOT transistor is probably shorted again and the transformer is causing it.

I have a sony wega trinitron, when the tv is turned on, (no visual, or sound) the red stand by light blinks 7 times, and you hear the tv click off? Please help


Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.

No picture or sound when powered up. Red Standby light flashes continually. My Sony KV 36 XBR250 Wega Trinitron XBR is about 10 years old and has worked perfectly up to this point. What could be the...


Did you get your set fixed or did you replace it? My same set did the same thing. Turned it off for 2-3hrs after watching it and when I tried to power it up- nothing but the sound it would normally make just before the major power up, sort of a relay click sound. No picture or sound but the red light blinks non-stop.

Power red light comes on and blinks off you can hear it click but doesn`t have picture come on. i must unpug my tv other wise it keeps on clicking.


Greetings!

You have a great little set. These made a great picture. It is impossible to tell without inspecting it myself, but the most common things we found on this era of Toshiba was open flyback transformers and shorted horizontal outputs. Neither of these do I recommend you attempt, because you will be working in the high voltage circuit and can subject your self to unhealthy voltages (in excess of 30,000 volts). Refer this to a qualified technician, but a fair and honest one who will charge you a fee that will make it worth repairing. Make sure he/she checks the socket on the picture tube, too.

Good luck,
Rob

Our sony will not turn on, we hear the click but nothing.


The 7 blinks usually indicate a high voltage problem (voltage too high). It can be a simple regulator problem or something more complex. Please update this to confirm your model as KV-32FS120 and some indication of whether or not you wish to attempt the repair yourself.

Thanks,

No picture


This mogiht be a problem in the High Voltage power supply. Or the Horizontal output section of the TV. I would start off by checking the Horizontal Output Transistor and the using a high voltage probe check the CRT anode voltage to make sure it is proper. If you do not have a background in electronics I would not suggest that you attempt to work on this set.

No sound or picture now


The set may have shorted the horizontal out put transistor since it kept coming on sometimes. This could be cause by the driver transformer arcing causing a "spike" in voltage going to you horizoltal out put transistor. Stargazer

Power up then off, no picture, blinking red LED


The high voltage does come up but the set goes into shutdown because is sensing a problem somewhere in the set,the shutdown circuit gets activated when the high voltage is too high, a problem in the horizontal deflection circuit or because there is a problem in the secondary of the output transformer,this transformer helps develop voltages supplies and if one is missing the set senses the problem and shutsdown,there is another possibility and is related to the picture tube,there is a resistor in the crt board ,it should measure 51 ohms only ,sometimes it opens up and gives you same symptom.If you are familiar with tv service you can check this resistor and be alert of the other possibilities,if you are not too familiar be safe and get assistance from a servicer. Let Us know how it goes,or if you need more information.
