Help...Sony KV32S20 won't turn on

mallik: Who are we to argue with a tech that was actually at your home and took the back off of the television and performed testing and troubleshooting? The quoted repair price does indeed sound reasonable since it includes repairing the television in your home or pick up and delivery to and from the shop. You might want to get some references for your chosen shop. Talk to previous customers. If you are in doubt, get a second shop to give you a repair cost estimate.

Hello,

It's stranger that both circuits go out at the same time....

Be aware Sony is known to have bad solder...

Ask a second repairman to see if he tell you that these circuit are gone... If he tell you another thing...be aware...

Ciao

Rifo!

Why? If regulation goes out on the B+ for the HOT, it'll often take the HOT out as well.

Tom

Fabri: Not strange at all. As you know, both the power regulator and the high voltage circuits are interconnected with each other. If the high voltage circuitry shorts out it will then take out the power regulator circuitry that feeds it......... or if the power regulator circuitry fails it can send too much voltage to the high voltage circuitry and make it have component failures. This is "standard stuff" with all television circuitry.

gone...

news:

Pippy!! Sounds like you have Zero experience with these Sony,s

Pippy..... and your quoted price to replace would INCLUDE the home service call or transporting the television to and from the shop ???? .... and you are certain that the other components in the SMPS are OK.... and HOT, flyback, etc are OK ? Get real.

h- output shorting and blowing power supply transistors, and resistor very common issue with that TV. price sounds about right.

Yes sure...

But what I want to say, it is stranger that both circuit completely gone.. Because if High circuitry shorts there are fuse resistance or some protection on the principal alimentation that avoid the complete falling of the circuitry..

So I'm ok with you, some components on both circuits can be out of order... but i doubt that all the high voltage stage AND the Power stage are out..

This is why i think that a second estimate could be useful...

Have a nice day! "sofie" a écrit dans le message de news: snipped-for-privacy@corp.supernews.com...

voltage

You did notice that it is $285 Cdn, right? :-)

Tom

I repair those sony TV's all the time. the power supply is ALWAYS blown when the h- output goes. I have also seen no protection for the power supply from the h drive circuitry

pippy: I take it from your comments that you do not work in, manage, or own a repair shop. By the time you pay for the shop overhead, vehicles & gasoline to go to and from the customer's home, wages, insurance, etc...... $285 Cdn is just about right for that type of repair that will undoubtedly involve more than just one area of the circuitry. $285 Cdn = 213 USD
