Question about Sony KP-51WS510 51" Rear Projection HDTV-Ready Television

1 Answer

Sony Trinitron Model KV-2654R, Manufactured 1983

Sentimental reasons keep me hanging on. There is a blown capacitor on the main circuit board @ C-566. I'm trying to identify the replacement part without purchasing a schematic. Did I also mention I was cheap!

Sony kv 32hs500 after blinking does not work.it makes a ticks noise and after 7 blinking does not turn on.


1st POSSIBILITY - usually after 4 or 5 yrs EHT ( transformer that supplies voltage to tube ) becomes weak - then TV won't get ON.. means no picture no sound ( in some TVs ''garrrr'' like sound comes - but it is rare) ..... but LED blinks - in some TVs along with EHT 1 or 2 components like resistor, transistors, etc will also gets deffective

2nd POSSIBILITY - main capacitor (very big in size) is blowing off


i think in your case main capacitor is blown

- so solution is TV circuit board has to be checked to find whether only EHT is deffective or other components are also deffective - price of EHT will be between Rs.250 (US$ 5) to Rs.600 (US$ 12) & price of capacitor will be between Rs.50 (US$1 ) to Rs.150 (US$3)

- iam service engineer (computers, laptops, printers,etc) - bangalore - domlur - 09986222774 - sathyavijayasarathibabu@ymail.com - if you are in bangalore then you can call me for service


I think you are in america/australia...side ----------- i don't have any idea about EHT transformer's price & service charge in your place..............

My sony wega trinitron 32: kv-32fv16 will not come on any it was manufactured in 2000 can it be repaired?


hi,
Yes, it is repairable. Check the power switch and fuse. If the fuse is blown, try to replace it with same value. But if it blows on second time it means that there is a short circuit..You need a service technician to have it repaired.

Sony Trinitron Wega TV keeps shutting off and red


There are two Ic's that need replacing on the Deflection Board (D) board.. These regulate power for the High Voltage and Chopper PWM circuits. The IC location on the board are IC6501 and IC8002

Standby lighy blinks tv won't turn on


error code 4 is vertical deflecton failure . replace the vertical deflection ic. and the electrolytic capacitors in the vertical circuit. Or if you are lucky just resolder the vetical IC and resolder th horizontal section too.

How to turn standby off


The TV circuit may have detected a problem within its parts. You may have to check some leaking capacitors in the board or loose solders or burned components just to make sure. Normally leaving the TV unplugged overnight should reset it.

Tv clicks then turns off red blinking light blikns 7 times


The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

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 FD Trinitron Wega KV-34HS430 TV


Since this seems to recover for a while, I'd first look for poor solder connections on the board. If you can solder, resolder any connection that appears grainy or has rings. Let me know if that resolves the problem. If not, the likely part is a bad capacitor in the kine bias circuit. I'll look up your specific model in that case and get you specifics.
