1st check +200Volt are at RGB Board (mounted at CRT gun) if volts are correct, picture tube (CRT) is defective and need to be replaced. Regarding Schematic (service manaul), its available on charge basis.

    at neck board (its R-G-B board mounted at CRT neck) check +200 volts. In my opinion, +200 volts are not available at neck board.

Turn on my Sony FD Trinitron WEGA KV-32HS510 32" TV, you hear a click, and then it blinks 3 times pauses and repeats.


Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672. This is the fault with 3 blinks. If you wish to get more, check the site linked here.http://electronicshelponline.blogspot.com/ Pull up previous posts, either by brand search, or view it in Mosaic / Timeslide / Flipcard option.

My tv sony wega dont turn on an the standby light blinks 16 times model KV-32FV310


Hello
Standby light on Sony TVs blinks 16 times is abnormal I thiks. It may come up to 8 blinks or so. You jsut switch off the set by AC mains switch at the front panel, switch it again with it and count the exact numbers. Never switch it On_Off by remote hanset.
If it happens even after this process, you just do the following
Press the following button on your remote control as stated
"Display"_"Channel"_"5"_"Vol Minus" [not plus] then "Power".
You may get "OVP" "OCP" "V STOP" etc displayed on the screen.
Just report the result to me through Fixya. Ok.

Retrace green, relay on/off..when turn on the screen is green and after a few seconds it turns off by itself


Oh dear ! I fear my answer may not be what you want hear but my advise is free. Bright green raster with Flyback (retrace) lines may indicate a heater cathode short in the tube (crt) this causes a sharp increase in beam current and the power supply shuts down into standby mode. To prove the point isolate the red and green cathode pins on the tube base and cross couple the red video output stage to the green cathode pin and the green output to red cathode pin using wire links. If set now comes on with bright red raster the fault is in the green video output stage and not the tube. If still bright green then tube is most likely cause. Gently tapping the tube neck may prove the point, but take care the tube neck is thin glass and if hit too hard will break compounding your problems. WARNING if you do not feel totaly confident to attempt this level of repair there is no shame in seeking the advice of your local service technician. Safety first always

IM A TV TECH. I HAVE A SONY LCD KP-60XBR800 I HAVE NO RASTER. POWER OK, MENU OK BUT NO RASTER ON TUNER, TUNER VOLTS OK,CAN YOU HELP ME PLEASE. THANKS my email sergioaguirre0182@hotmail.com


check the high voltage with the screen control turned up high where there is no raster. suspect problem within the video circuit where there is no high voltage or defective picture tube.some time when the screen is black and the screen control advanced,you can see if the tv has video or vertical or horizontal problems on the screen.service the high voltage circuit if there is no raster or high voltage is seen.no raster can be caused by the no heater or filament in the CRT.---- a defective picture tube can cause many problems, such as, poor brightness ,missing colors,intermittent picture,poor focus,a single-colored raster,arching in the gun assembly,retrace lines in the picture,negative picture,chassis shutdown,noheater or filament lit and no raster to name a few.an open filament or heater can cause no picture or no raster symptom.a defective CRT can have an extremely bright screen.loose particles of the cathode element can lodge between the grids and cause an intermittent black and white picture. simply tap the ends of the CRT gun assembly and notice if the picture begins to flash off and on.---- with a leaky picture tube after turn on the raster dims and get extremely bright.a dim picture with no green in the raster can result from a bad green assembly. a heater-to-cathode short can cause a raster to change colour or a result in no raster at all.replace the picture tube if there is severe arching in the neck of CRT. excessive brightness with retrace lines and a vertical collapse to a thin line can be caused by a bad coil on the neck board of the picture tube.rejuvenate the picture tube when there is very bright green screen. check for the resistance change on the resistors of the CRT neck board for an excessively bright picture with retrace lines.excessive dust inside the CRT spark gaps within the picture tube socket can cause the very bright raster and the chassis shutdown.a defective video amp,luminance buffer,or reference transistor can cause a bright picture with retrace lines. -------- for getting any required parts to replace you can get it from www.radioshack.com or from www.partstore.com or from www.shopjimmy.com --------- thanks.please do rate the solution.thank you for using fixya.keep updated.

SONY TV PICTURE TURN GREEN WITHOUT RETRACE


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.

Phillips/Magnavox 9P5544C102 white raster and shuts down


This denotes a problem called blooming the horizontal lines you see are called retrace lines this is caused by the increase in anode voltage which could be caused by an increase in HV section current which trips the overcurrent protection dircuit and turns the TV off.If you do not have electronics experience I would suggest taking the set to a TV repair shop.
