K3569 transistor not found, so tell me what is substitute this transistor?


Follow this link in order to get to the substitute for your transistor (2SK3569) from On Semiconductors. Check that your ...K3569 is also a Power MOSFET N-Channel transistor.

In case of a problem or clarification or further details needed, don't hesitate to post me a reply before rejecting my answer.

I need to know the datasheet for the horizontal's transistor for a tv RCA 32F531T, because I lost the replacement


Hello
The number of horizontal output transistor is [TL 035]. If this number is not available, you can use exact substitute after reffering it to transistor data book and equivalents. OK.

When i put my tv sony trinitron on, i hear the sound for 15sec en then the tv go out en de leds blanks


Hello
There is some sort of indirect short inside your TV. It is in the main circuit board. Most of this kind of fault in Sony Tvs are related with horizontal output stage. You just replace the horizontal output transitor [which drives the Line Output Transformer] of your TV first. If the transitor is leaky, the above said falult may occur. If it doesn't help Line Output Trnasformer [LOT] may need replacement. Check whether the replaced transistor overheats within seconds or minutes. If it overheats the LOT is faulty. Ok.

Unplug the PS-15KX 120V AC cord !! Then take cover off. DO NOT plug the AC cord in unless you are used to working around a lethal voltage and current !!!!!!!!!!

If you can use a Multimeter, then measure resistance across each pair of the 3 leads of the output transistors. You will probably find fractions of an ohm across a pair of leads. One or both may be shorted. NOTE: Do not ever measure resistance in a powered up circuit, kiss meter bye-bye and maybe burn you too.

By putting more robust transistors in this supply, you may not gain much reliability. The supply is rated at a continuous current draw, which is less than the intermittent current they advertise. Read the spec's of any power supply you get and look for continuous current ability.

There are several better transistors that will substitute for the 2N3055. You will need to look at a transistor substitution book and check specs. The internet is great for this. I used to use all kinds of data books, and still have them! But looking up info on-line is nice. Motorola has some that will fit and have higher current and voltage ratings,

Get someone who is a ham or geek if you aren't sure about sticking your fingers in the power supply.

Be Careful, Work Safe, it is a factor of longer life.

Horizontal cct transistor


Hi,

Specs for a 2SC1258 Si npn 28W 36V 18V 5V 3A 200>C 250MHz - 15/250 manufactured by NEC in a TO128-1 packaging.

Replacement/substitute or equivalent would be BLW15, 2N5938 or a KT934V.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
