I had the same problem, my telly was showing error code 5, led blinking 5 times and then the telly enters into standby mode. There is a great site with pictures of this telly and I found the answer here:

Error Code 5 - Tube Gone

Hope it helps.

My first guess is IC 702 in the crt drive circuit. You could open the back and unplug the "C" board from the back of the crt and then power it on. If the set comes up and you have good audio that will isolate the problem.
If IC 702 is the problem you'll have a couple of other things to check, R533 .47ohm 1/4 watt fusible resistor and C541 22uf 100v both on the "A" board because they tend to stress when IC 702 begins to leak. Replacing IC 702 and not the resistor and cap could cause 702 to fail again.
If IC 702 is not the problem then it could be the flyback.
Hope this helps!
Bill

SONY TV. STANBY TIMER FLASHING


Hi Frank,

Please let me know if it has a pattern of blinks (separated by a pause) or it will flash an exact number of times. Your unit (KV-34HS420) has a built in self diagnostic software that will indicate the probable caused of the fault by flashing of the LED at the front panel.

SONY TV MODEL kv-27s40 BLINKING RED LIGHT 2 BLINKS


The 2 blinks usually mea an over current problem. Perhaps the most common cause of this is a shortde Horizontal Output Transistor (HOT). If you can solder, you should be able to repair this yourself. Realize that there are potentially dangerous high voltages present inside the set even when unplugged. Look for a 3-legged ransistor attached to a heatsink close to the flyback (part with large red wire coming out the top). The part will be marked C5438 or something similar. Post that marking here nad I'll confirm the entire part number.

Keep us posted.

My sony TV wont turn on.


Un plug and let stand for one minute. If it still does blink then use the reset on the remote and press it while pressing the power button on the TV.

Sony Vega Service Codes


KV-32HS510 and KV-27HS420, seven times blink error code shows problem in Horizontal deflection circuit.

There are many possibilities like dry solder joints, weak capacitors, Horizontal transistor short or flyback transformer fried etc.

If you have little experience of TV repair and good solder skills and have necessary tools to test / check defective parts, then you can make it. you also need to have related service manual to see board location, schematics and part numbers.

Sony Trinitron KV-32FS320 5 blinks


Sony KP53HS10 5 blinks
Five blinks means "Video out abnormality detection". Possible problem areas are as follows:

Video out, IC7101, 7201, 7301 and others in C board circuit.
Q510, 516, 524 (A board).

There are actually three C boards, the CR, CG and CB boards. They are attached to the rear of the red, green and blue CRTs, respectively. I wouldnt attempt to repair the set myself. I would solicite the services of an authorized Sony servicenter.
