Question about Sony Grand WEGA KF60XBR800 60" Rear Projection Television

1 Answer

Turns off turns on standby light flashes

The same others describe. I read your solution and wonder how much it will cost to have the horizontal sweep adjusted or the vertical power supply replaced. Thank you.

    Hello,

    Yes I have the same problem, after 2 minutes the Sony will turn off, if I do nothing it will eventually come on then off again and repeat the same thing. When it goes off and I turn the power off the power light will blink 5 times and will do this a few times then the set will shut off. The picture is as bright as usual when on and I can hear the fan running.

    Is it possible the light can be drawing too much current, or some kind of sensor for the fan that can be plugged?

Horizontal sweep absent, is the fault. Vertical sweep is OK. Check for any loose solder terminals or loose connection at the connection goes to deflection yoke. Check all the capacitors related to horizontal scan output. google.com/+GopakumarGopalan

My pioneer vsx 815 amplifier has a flashing blue standby light. Have tried resetting by pressing enter and advanced surround keys. All it does is flash a few other LEDs and then goes back to the flashing...

"enter and advanced surround keys"? I don't see that documented as a special function in the manual.

BTW: other than the Flashing light, is there a malfunction?

Page 72 describes how it REALLY resets...

Resetting the main unit

Use this procedure to reset all the receiver's settings to the factory default. Use the front

panel controls to do this.


1 Switch the receiver into standby.


2 While holding down the TONE button, press and hold the STANDBY/ON button for about three seconds.


3 When you see RESET? appear in the display, press ENTER .

OK? shows in the display.


4 Press SYSTEM SETUP to confirm.

OK appears in the display to indicate that the receiver has been reset to the factory default
settings.

Flashing green light and black screen


Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Pull up older posts.

My KV-36HS500 won't turn on it sounds like it wants to,but no picture,and standby light flashes 7 times,pauses and flashes 7 times again


The 7 blinks indicate that the horizontal deflection has stopped. This can be because the horizontal output transistor has shorted (common) or other defecive parts. If you are familiar with working inside of sets where potentially dangerous high voltages exist and can solder, let me know and additional details and instructions will be provided.

RE: Flashing "Standby" light


LED blinking Seven times. High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.

Sony blinking standby light


This is Sony's way of telling you that there is a short in you set.Probably the horizontal deflection circuit.(Horizontal output transistor shorted??). Also any other short. You need to take it to a techincian and have it checked out. It would be wise to get an estimate! Stargazer

Doesn't turn on, but LED blinks 5 times


The flashing light is an indication of the sweep falure. Most of the time it is in the sweep output section, like the flyback transformer and or the horizontal output transistor. Most of the time it is the flyback that causes all the problems and componet blowouts in these sony TV sets, but it is also sometimes the vertical output IC that shorts out the sweep power supply. In any case a solid state set is no where to be experimenting around with and should only be worked on by a trained service tech. Good Luck

The unit powers on and off.


There is a short somewhere in the sweep Horizontal, or vertical, or the sweep power supply has a fault. not really a job for the consumer , unless you know about solid state electronics.
