Question about Sony KV-35S65 35" TV

1 Answer

Works fine 30 minutes then no picture

Hi , I had no power at all. So I replaced the IC601- MX0841 , R607 - 0.01 ohm resistor, Q502 - C5148, and flyback. When I powered up everthing was great for the first 30 minutes then the picture went out but the sound was still working. I unplugged it and plugged it back in. The picture came back and stayed for about 10 minutes then went out again. I resoldered the driver transfromer and most everthing else on both boards

It will stay on for about 30 minutes from a cold start and 10 minutes when warm. Any Ideas?

Q502 must be top-shelf , first-quality only = no generic.
Use RCA 237470 or Sony 8-729-035-75 Both are first quality,
but RCA much less expensive..............................T.

Please rate this solution......................

Note:Blow-up caused by bad connects in horizontal driver
circuitry.Therefore,save your good,used flyback!

    After further consideration, the reason your pix blanks out is

    a bad CRT......common on S and V line Sony.........T.

TV won't power up after surge


Try this: unplug the set and wait about 10 or 20 minutes. This is to make sure that the main power supply filter caps completely discharge. Look on the power supply board, close to where the AC cord attaches to the board. Look for a white resistor labeled "0.1 OHM" (the symbol for OHM, like an upside-down U) and measure it with your ohm meter. If it is open then your switching transistors in the main power supply are most certainly shorted. Older sets had 2 separate transistors on little heat sinks labeled "C4834", then they switched to 2 transistors in one package labeled "MX0841" or "MX0842", and then some sets went to two separate MOSFET transistors. Measure those parts and post your results and we will guide you from there.

Sony KV-35S42 35" keep blowing MX0841 and .1 fuse resistor


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

KV27S42 dead - 4 blinks


the +13 and -13 are generated by the flyback transformer as well as the 200 volts. the 135 is your B+ voltage and sould be there at start up. check the HOT and the Flyback. if there is no 135v check IC1751 on the C board sometimes if bad it loads down the 135v line. and can give a faulse vertical error.

Clicks - but no picture!


According to the manual... Problem: 'a red light keeps flashing on the tv for more than a few seconds', What it could be: 'your tv may need service', What you can do: 'Call your local Sony Service center'
