There is some loose soderings in the horizontal output section of your Sony Tv. it is common to get the lead solderings of the components which get heated during working; and will caus loose soderings to occur there in long run. Take out the printed circuit board out of your TV, turn it upside down, and resolder most of the suspected points at horizontal output section by applying a little more solder, without making any solder bridge in between adjecent solder point. This must solve your TVs problem. OK.
Hello melanie Hi, in my experience as a TV technician, that would usually be a shorted part, the horizontal output transistor, that part powers the HIGH Voltage section. Very Lethal, the power supply detects this bad part which in turn makes the unit go in standby so as not to damage the TV much further. mMy advice is go seek a tv tech to repair the part.
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.
try to plug in again...if there's no reaction at all, then the power suply section may checked...(I.C. regulator str.... followed the horizontal output transistor or some of the zener diodes regulator or broken PCB line
You Probably have a bad flyback transformer(The HI VOLTAGE) and a defective horizontal output transistor. I you have training in the tv repair , then you can go to http://www.partstore.com and getthese parts. they arte soldered in so your gonna have to know how to solder and unsolder as well. You should also know all the safety issues regarding the HI voltage in these sets. If you dont I highly advise that you take this set to a pro for repair as theres hi voltage inside these sets even when they are unplugged. Good Luck
The blinking light means almost 100% that the high voltage circuit has failed. Probably need a new horizontal output transistor and flyback. Perhaps an associated resistor or diode. If you have the expertise go for it, otherwise take it to a professional. In any case be extremely careful and safe. Good luck.
oh an easy one LOL That part # is 1-453-268-21 and available at http://www.partstore.com at a price of $82.12. One thing though Make sure you check the horizontal output transistor with all the leads disconnected from the curcuit as this part sometimes goes bad when the fly does. My regular practice with any flyback replacement is to automaticly replace the HOT(horiz. output transistor) as well as resoldering the hhorizontal driver transformer and the horiz. driver transistor. Hope this assist yout repair and makes a happy one. Thats what were here for! Good Luck.
