Please my tv with on the standby mode when i try to put it back it couldn't the indicator now goes on and off with picture show please help

Depends on what is causing it...

Vertical bands of faint black are generally caused by filtering capacitors and can be found in the power supply or the 5 volt supply or even the Video processing circuit...it is not an easy task to identify the source of Video hum bars.....we also call them Jailbars.

Another problem seen is faint black lines caused by the TV set being in 4:3 mode all the time....right at the edge of where the picture ends and the black pillars begin, we see a faint black line that never goes away and is normally seen with a full screen....

That is actually image retention, but it's caused by the crystals that create the picture becoming polarized or ionized over a very long period of time....and it's not easy to DE-Polarize them !

But there are some theories out on how to do that....
Certain people suggest running the TV overnight with an ALL-WHITE picture and some suggest an ALL BLACK PICTURE...and some suggest alternating between both !!

Now, a black picture is easy to make, you just deactivate the Video Mute (blue screen) and set it to an unused Video INPUT overnight....

About the only way to make a white screen is to use the USB port for pictures and take a very bright outdoor shot of a piece of white paper that hopefully is out of focus too....That would create an all-white picture that you can plug into your TV set overnight....

Now if you decide to try this, deactivate any displays on your TV set...all you do is press the display button until the Video and/or USB input numbers disappear....

Next day , set it back to normal TV and see if it's gone or if it's REDUCED....try it again if needed, or try the exact opposite if you see NO RESULTS....

Look for swollen caps on the power supply and replace if needed. If caps look good, then replace your main board

Hi beinhauert,

The symptoms you've mentioned indicated that the unit turned to standby mode. This is an indication that there's something wrong on the TV. To help us narrow down where the fault came from, please access the built in "Self diagnostic Screen". Follow the steps below.
In standby mode (red light is on), press the button on the remote control in sequence "Display", "5", "Volume (-)", "Power". Self diagnostic screen's displays its log of error. Please let me know the error code with corresponding numerical value "1" means error has been detected, "0" means no error.

Whenever a television starts doing this the motherboard/main board and or power supply is usually at fault. The power supply can usually be rebuilt for around $150 depending upon the knowledge and skill of your local television repair shop. To replace the parts is usally more expensive then it would be to purchase another television ($300 and up). Are you sure this is the model number of your television because this model number is not for a CRT television. For troubleshooting you can unplug it overnight to try and power cycle it but it sounds like your problem is beyond doing any type of power cycle to get the television back going again. It would need the repair shop or to be discarded for another.

Hi.

The TV stays in standby because protection circuit kicked in.

Protection kicks in when an internal fault had been detected.

In your case the SCART cable may have caused a short.

When on protection the TV will stay in standby, will not respond to buttons or remote, and will not start up.
All higher voltages from PSU get shut down by controller board, and only the +5V remains on.

To attempt resetting the TV, disconnect all video cables, disconnect the power cord, wait about one hour and plug it back.

If TV does not restart, then there may be an internal fault.

In that case leave TV unplugged for longer, just in case.

If still no luck, then call Sony to discuss a repair. The number is listed on your owner manual.

If instead TV will restart, do not use the faulty video cable again, this can damage your TV.

Regards

helloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

hello if the lamp cover is not mounted securely the self diagnostic function works and the power /standby indicator flashes 3 times when you've corrected it power/standby indicator goes out the tv enters standby mode

Picture goes to high green with retrace lines that shows picture tube is defective and requires replacement.
Usually in above symptom, TV goes to standby mode and standby light blinks when green raster problem occurred.
New TV is better option because picture tube of KV-34XBR960 would not be available any more.
Thanks.

All symptoms in your TV shows that you need to replace its Lamp as it has been consumed its life hours and TV requires new lamp. Lamp can be obtained from Sony Website. Price is $200, Hope this info will help you to enjoy your Sony TV in coming days.

The curved picture indicates failing parts in the pin amp section and probably some faulty parts in the scan amplifier sections. The set is being turned off by the uPC because there is a fault indicated, and it is going in to protect mode.

The set will have to be properly serviced.
