How do I repair the Sony Bravia LCD HDTV?


Hi... If it is a power board problem it is most likely capacitors that fail. Look for any electrolytic capacitors that are bulging on top. They are normally round with an aluminium top with a cross marked in the metal. They fail over time if they are low quality or high ESR with high transient voltages.

Make sure that you replace them with same or higher voltage ratings but with the same capacitance.

If you do buy them for stock in your repair shop look for high quality low ESR variety that will not a cause comebacks.

Hope this helps!

Kdl40v2500 red led blink 4 times


In most cases the standby light might blink with different rapidity to indicate a fault relevant to the processor. It is possible that most of these indicate that there are errors in the processing section . Since there is a possible short or leak in the circuit the output driver section can take in huge current to trip the SMPS or from advice from the micro processor. Remove the power plugs and make sure that high voltage sections are discharged of the potential stored in capacitors. Look for visible signs of leak or of busted capacitors. Look for bulged capacitors or damaged components- burnt or busted. Use a multimeter to check the continuity or shorting in components, if so detach from circuit and test . If the voltage builds up and the set power ON and then shuts up then the suspected section must be checked in detail.

The processor must have the +5 voltage to the function properly , the +B and secondary voltages also must be checked to infer the fault. Trace with caution and in running through the signal path , circuit trail.

Check for tips to check the SMPS unit:

I have a Sony Bravia Model KDL40v2500, Serial #8057846, manufactured November 2006, that does not give any picture or sound. When we turn it on it clicks a few times and then goes into some sort of standby...


could be blown caps on your power board. if you dont know what they are i dont recommend doing the work yourself. take it to a repair shop. if you feel comfortable taking it apart you can check and see if any are buldged on your power board.

Hope this helped/ Please take a moment to rate :] Thanks!
