Hi,
1st set Brightness and Contrast settings to 50% at tv menu.
You need to cover 2 CRTs with any thing like thick paper while adjusting 3rd CRT.
For example, lets adjust Red CRT G2 volts, Select audio-video input 1 and cover green and blue lens with paper note-book and rotate Screen control up to level where you see retrace lines on projection screen, now decrease screen volts (G2) so retrace lines disappear and projection screen should be blank.
Now do same process with green and blue adjustment while other lenses should be covered.
Im not sure I conveyed it to you properly or not because English is not my 1st language.
Thank you.

    Technically if one of three CRTs produce inaccurate "cathode signal", total of "IK signal" will assume as bad or wrong and TV goes to respond as error.

How can I turn the screen voltage up?


On many Sony CRTs, the Screen (G2) voltage pot is located on the neck board instead of on the flyback transformer.

SONY KP-53S75 tv problem


the four times is a code for what part of your tv is having issues. A Qualified Sony Service Shop should be able to give you an idea and or cost of what the repair is. 'Call around'
1) My thoughts is that there is either an HOT, 'High Output Transistor' that has gone out or maybe even a flyback that sends the High voltage to your 3 crts.

When i press the power button the stand-by light blinks orange about 10 times and goes red again. and the tv never comes on


The blinking light describes the nature of the problem to the service technician. The error message varies from manufacturer to manufacturer and model to model, so more information is necessary to provide an accurate solution.

If this is a Sony Projection Television, (for ex the KP51WS620,) 10 blinks, pause, 10 blinks, etc. means "Hgih Voltage Protection" and the probable cause locations listed are as follows:

1. Q8014 or Q8013 have shorted replace along with R8051 on D board.
2. IC8005 is damaged (D board).
3. G2 is improperly adjusted.

These are starting points for a qualified service technician. I hope that helps.

No picture


first of all sony uses blinks as a means of an error code, on older models like yours could be weak CRTs, try turning up the screen controls a little, if the picture comes on the CRts are weak and AKB is holding them dark. the controls are in the front behind the cover.
possibly you have no high voltage, D board or splitter is bad, bad convergence ICs will cause NP, check the 3.15amp fuses if any are blown replace ICs both stk392-110 and fuse to fix.

I have a SONY KP-53HS10 TV and the picture will blink on and off after it is on far a time. I have sound, but the picture go on and off. The red stand-by light at the bottom of the screen flashes before...


I have over 10 years experience in electronic tech support.

I know this isn't what you want to hear, but the problem you've described can't be fixed with troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. If you're still in warranty, the TV will be repaired at no charge to you. The warranty would likely be at least one year from the date of purchase from the manufacturer. If you purchased an extended service plan they will repair the TV at no charge as well.

If the TV is no longer in warranty, it will likely cost a minimum of $150 parts and labor. This is assuming that you only need one circuit board or small part. If the problem is more than one of the circuit boards, the price of repair could go much higher.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please let me know if I can be of further assistance.

Reducing voltage for Sony KP-51HW40


G2 = screen...On the screen controls behind the front grill, behind the hardboard. 6 pots, 2 rows of 3 pots. 3 for focus and 3 for screens. 1 for each of the the red, green and blue guns/crts.
To adjust: Run set, change to black screen with tv/video button. Dial each screen clockwise untill you see a color. Then counterclockwise slowly untill that color goes black, then stop. Do this for all 3 screen controls.
If you need to adjust the focus then bring up lettering. I use the QVC channel for this. Focus is done by eye.

Something is preventing the power supply from operating:
Possible causes in order of likelihood:
1) Convergence amps failed overloading the supply (See if you can disconnect them)
2) High Voltage circuit has died. (Right on schedule if your TV is 10 years old)
3) One of the CRTs has shorted
4) The power supply itself has died (Is there a lot of dust covering it?)
See if you can isolate the failure by working down the list.
Hope Ya Fix it!

Sony Trinitron KV35V36 Blinks Every Second


Picture blinks on/off and audio is still there?? If so it's the crt and a common thing for sonys to go out like that.. You can lower the G2 voltage a bit and that might help for awhile or have the tube rejuvenated by a technician - but either idea is only a temporary fix...
Sorry

TV fliockering on and off


Unfortunately that's an indication of the crt going bad in a Sony.
You can turn the G2 voltage down on the flyback or have a tech rejuvenate the picture tube but either of these are only a temporary fix..
The flyback is the rather large transformer with a red (anode) wire coming from it and attaching to the crt. (looks like a suction cup).
There are two adjustments on the back of the FBT, one is screen (or G2) the other is focus. With the unit on turn the G2 counter clockwise just a little and the picture will get slightly less bright. That should stop the picture from blinking out - or doing so as often. But again, it's only temporary!
Good thing Santa's almost here... :)
