Normalmente cuando falla la fuente se dañan los transistores convertidores, la resistencia 607 de 0.1 ohmios los condensadores C609, C610 de 0.47 mf. C611, C612 de 0.22 mf.
En nuestro caso basto con cambiar el MX0841 y R607, ya que el daño se debió a una sobrecorriente provocada por la salida horizontal, esta fuente e mas robusta que la de otros modelos ya que accidentalmente se provoco un corto en la salida del B+134 y simplemente solo se daño el MX0841 y la resistencia R607, se cambiaron y la fuente volvió a funcionar perfecto

Check the H.O.T. as well, probably the 2sc5148, this is usually what causes the pwr supply failure on the sonys. chk out www.acme-sales.net, they have kits with everythng u need for that repair

No Display, no sound- not working, showing dead. But input Power is ok. Picture tube filamment not getting power. model sony KV-2192M3

Hello
Check the input fuse first. If it is blown, there will be some short inside the power regulator circuit. Usually Sony sets uses STR regulated power supply. You can see this STR, and Ic, screwed onto a heatsink. Replace it with a same type and number. Before replacing the STR, check the diodes used in that section for damage, mainlu zener diodes. They might get shorted along the blowing of the STR. Check that section throughly before resoldering the new STR.
If any further assistance you needs, get me through Fixya. Ok.

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.

Power button doesn't do anything, remote doesn't work, 4 blinking lights. Sony kv 36fs120.

you have power issue. short the prongs for a minute. then remove the short wire. then test. if not succesful go to your nearest service center.

I have a Sony KV-32S20 32" TV and the red standby led flashes constantly. From what Ive read does that mean an an I.C. tv chip # mcz 3001d is bad? I also read that replacing the R-536 with 1 ohm resistor...

you first must verify you have horizontal deflection. do the crt fillaments light up? if they dont you probably have a shorted horiz. output transistor short or a bad solder joint in the drive circuit. i would solder this anyway it is a common issue. it can blow up the power supply if it fails. if they do light up turn up the screen control, the bottom control on the flyback transformer, do you have a flat vertical line? if so you lost vertical deflection. that could also be a bad connection on the ic or it failed.

6 horizontal lines

I would look for a Vertical circuit failure. Most likely is the vertical output IC and or open resistor off the hv transformer. Definitely look for any loose solder connections around the Vertical output IC.
Hope this helps,

Help me to resolve the problem

The problem of resistor of keep blowing caused by surge voltage,look for capacitor associated that resistor.The capacitor hold the voltage and distribute the exact volatage to that resistor if that capacitor is shorted or leaky,that is the caused of abnormal distribution. Also check the diode there and transistor.What is the number of IC driver you replaced,and do you have already schematic diagram?If not,i help you to give a links where you can avail.

Hope it may help you;

Sony CRT Tv (KV-T29SZ8)

When you see white lines at the top of the screen, it means that the pump-up capacitor next to the vertical output IC is bad and the IC is about to quit. When the output finally quits, you get a black screen with possible dim spots. The vertical output IC and its pump-up cap will have to be replaced, and the little fuse resistors next to the flyback in the + and - supplies to the vertical output IC must be checked too. If you have experience working on TV's then you can do it yourself, but if not then have the set serviced by a tech experienced in Sony sets.

Black screen

If the power supply IC (MX0842) shorts out, it blows the Sony 0.1 ohm fuse resistor. The set will click but have no sound or picture and the LED will blink 5 times. The power supply should be repaired by someone with experience with Sony TV's.
