sony kv27v10 Can't Post
i have a sony tv model kv-27v10. <br>problem was it wont turn on.after testing i found q601,q602 shorted as well as q591.then the 607 fuse resistor was open. <br>q601 and q602=c4834 <br>q591=c4927. <br>i replace all this then tv turn on but after like 3minutes i so a thin black line on the right of the screen follow by a sound made by the fuse resistor which blow out. <br>then the same components went bad.what else could be causing this.thank you <br>
c4927 is the horizontal transistor and c4834 are switching regulators i think 7v regulators

Try telling us what these transistors do, you are on the ww web so for two reasons you want to give better details. !/ I may not have that circuit. 2/ I have the circuit, but blow you why should I search my files to find it. So be more specific and you may be a happier chappie.

Everytime,you have to resolder all power/horiz circuit..
also,check and replace VDR's in power supply.

Also R644,T605,Vdr601,did you use q591,q601,q602,only by Sony#8-729-0 missing some #'s.
