Question about Daewoo Televison & Video

1 Answer

Relay clicks, but No sound, No picture.

Re: Sony TV, Model #KV-32HS510, Chassis #DA4
When power button is pushed, relay clicks, standby light flashes six times, after a few moments of non flashing, light again flashes six times, and keeps repeating this.
Check voltages on different components in power supply, voltages would check normal, and then collapse when relay drops out.
Any help would be greatly appreciated

Hello, just try this first.

Unplugged the unit the power outlet for about 60 sec.Then power it on again. If you have surge strip along the line. You should directly switch in on power outlet only. If this doesn't help.

As the relay is working you have power in standby mode. Check its supply voltages if its ok. Secondly you can check the the B+ supply it is in DC, If this is a crt type tv, check its horizontal output transistor, Check its flyback for short circuit. Capacitor near to it rated almost 800V, and deflection coil.

Just for input, hope it helps

The primary power supply is good,maybe the horizontal output transistor is deffective thats why there is no high voltage supply in the picture tube because theflyback have no supply voltage and oscilation.So check the harizontal output transistor and replace if deffective.

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.

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 tv wont turn on, standby light just flashes


check for an open resistor on the power supply, it is actually a fusible resistor, (white) if open, then check the converter, some sets have two separate and some have it as one. it will be on a heat sink on the power supply. if shorted then check for a shorted horizontal output transistor and repair cold solder joints on the horizintal drive transformer which is the real cause of this problem

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.

This is usually an indication of a failure in the scan amplifier sections. When the scan amplifiers or high voltage sections fail, the main power supply will usually also require servicing.

It is very common that the fly-back and high voltage multiplier and also the horizontal output stage fails in these sets. Along with it, the power supply will usually require to be serviced. On rare occasions, the vertical deflection amp fails.
