(i) Make sure that the power cable from the TV is securely plugged into a functional wall outlet.
(ii) Then, check to see if the TV/Video setting is correct: when watching TV, it's set to TV, and when watching connected equipment, it's set to video 1,2,3, etc.
(iii) Check if the Parental control feature is activated. You can check it using the Parent menu.
(iv) If the LCD projection TV's power is ON, and LAMP indicator is flashing red then the lamp for the light source burns out. Replace the lamp with new Sony XL-2000U replacement lamp.
(v) If the LCD projection TV doesn't turn ON and a red light keeps flashing then the TV needs service.

This is a common problem especially with newer televisions. The capacitors on the boards like convergance board and other boards like y-sus have been going out.

Have you tried a hard reset (unplug the set from the wall power for MORE THAN 4 hours)? It sometimes works.
-----------------
If still the same problem then --- It seems most likely that the problem is either the backlight itself or the power supply for it.First check the power supply if it seems ok then its confirmed back light.in the tv on the main board there is a chip beside called inverter board get this inverter board replaced to solve the problem.the cost of the board is near to $100 and you can get it from

I would re check your steps. If you have a harness that is not hooked up, that is bad. It goes some where.

Sony lcd kp60xbr800 no raster in tuner all voltages ok. in tuner power ok, menu ok, but no raster please help sergioaguirre0182@hotmail.com thanks


You have a lamp driver error that can be and most likely is faulty and has to be replaced,Also i would not recommend you putting a bigger lamp unless the part numbers are the same to the lamp you are replacing.Moreover most of sony's error codes are the same from crt to lamp tv set like your lcd model tv set, the same concept was used to built your lcd tv set just with different features.

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.

The first thing to check is for dry solder joints on all parts of the circuit board you are having problems with, but as for that popping sound more often than not it is caused by a faulty capacitor somewhere. Hope this helps.

hey i just found out the problem on the my LCD tv model number kf60dx100. My brother is a technician and repairs all the big tv's like Plasmas, LCD's, CRT's,PTV's, and DLP's. He said that if you change inputs and the backround is like a blue ish color you'd have to replace the whole "light engine".......which is like the most expensive part in the tv....
