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.

Power light is on but no picture


you did not mentioned if you have raster or none, if your tv has raster but no picture your problem is in your I.F. section and your tuner, now if no raster, you can check your power supply, check your 5volts, 9volts, and 12volts check any alternatives that cause of no picture..

Sony KV-27HFR TV, no picture no sound; but got HV


The high voltage transformer may be the problem, because it feeds back secondary voltages to different parts of the set, for example is the vertical deflection voltage present at the ic, if memory serves me there should be around 26volts, if it's missing it means the fuse is open or the flyback pin is not generating the voltage.

Sony KV- 20FV12 get no signal on screen. Same cable outlet works on other TV as a test. Cable ON in menu. Auto Set search produces search but still no signal.


Hello

If auto search is going on smoothly, and there is no stations on air is memorized, and display no signal, there are tow possibilities. The first one is antenna is not connected properly. Check the antenna connection for firm. The second one is tuner fault. If the tuner inside the tV is faulty, or it does not gets proper voltage to work, this type of fault land display will see on screen. Check if proper voltages are comming to the tuner section in circuit board. If voltages are ok, and still there is no signal display, just check it with external video input. That is, connect it to any dvd or cd with AV connector, and set the TV to AV mode and play a disc. If there is picture, the video side of your TV is OK. If not, Video-chroma-RF jungle IC is faulty, and not the tuner. OK.

I have a sony lcd kf-60xbr800 no picture in any input or raster no picture in component only menu. i reset the set and still no picture. all tuner voltages ok. help sergioaguirre0182@hotmail.com. thanks


(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.

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.

Dell Ultrasharp 2005fpw


The problem you are describing is definitely a bad picture tube.please replace it or the problem you are describing sounds like high voltage regulation problems. The easiest way to tell is by changing from a black raster to a white raster. If the size changes quite noticeably or jumps alot then you have a regulation problem. The first thing to do is check your high voltage while changing the raster from black to white. If the HV varies by a large margin, then you have a flyback problem. If it doesn't, check the voltage at the collector of the HOT while varying the raster again. If the voltage changes alot then check your B+ line. Typically what goes out in this case is a capacitor(typically 100uf-350v or so) or the B+ regulator. Hope this helps.

No raster no audio,Zenith SJ 2065S5


as horizontal transistor gets very hot so no eht so no raster &no sound due to nosupply to vif & tuner. as hor output is getting hot please isolate supply to hor. section & check power supply output is ok as due to high voltage h/outout may get hot & demaged. if supply is ok check for leaky or short parts in hor output. 1 hor. output transistor itself if it is replaced that may not be of proper matching. 2 diode& cap.in eht section. 3 clean print near eht. 4 moisture near yoke due to rain in rainy season only. so keep it hot for few hours. 5 at last if all are ok eht or fly back transformer. re connect power to hor output after rectification
