Are u receiving any error messages via a blinking power light?

if so the blinking light signifies to a repair technician with capacitors or circuits are having an issue they can diagnose the problem via the amount of blinks in between pauses however it will require a technician and some specific tools and schematics to fix and it may be cheaper if its no longer under warranty to purchase a new one


Hope this helped

    Robb,

    Thanks for your reply. Not receiving any error blinking lites. No shut-downs or excessive currents.

    Jungle/Video IC601(LA76327) seems a little warm,but not excessive.Need IC pin-out. I'm a tooled

    technician without a schematic and your solution has not helped. Hit me back with another solution.

    O.K.?

Tip

White Raster with thin lines; Sound Ok.


White raster with retrace lines: No picture, Sound OK
(picture tube based telivisions.)

It is a common fault to occur in most of the CRT based telvisions, regardless of which brand it is. There will be sound OK, and a bright screen with thin white horizontal lines across; at about an inch space, all over the screen area. This fault may occur along with colur shades also, like blue screen with white retrace line, red screen with white retrace lines, green screen with white retrace lines. Let us take the first case. A white raster with white thin retrace line acorss the screen. These are call vertcial retrace lines technically. To make it mor understand, we have to go to some picture tube electrode details. There are three colour cathodes for a colour picture tube, Red, Blue and Green. Two girds are there called Focus and Screen. Focus grid is supplied with focus voltage which in turn determine the cocus of picture, and screen grid is supplied with screen volrage which determine the emission of the picture tube; in short. There is a final anode to all the picture tubes, which supplied with Extra High Tension voltage, can be located at the top side of the picture tube, to which the EHT voltage from LOT is connected with the help of rubber ****** and clip. Without these three voltages, EHT, Screen and Fcous, no raster will be produced. Therefore in our case, there is a raster, so, horizontal output section including Line Output Transformer [LOT] is functioning well, and as far as sound is there, tuner and video IF section are working well. In fact, all other section except, video output section is working properly.
There are three cathode points on the base card, marked as Bk, Rk and Gk. Check the voltages of these three cathodes. In our case, it will be very low or approximately equal to zero. When cathode voltages goes low, emission of the CRT increases, is the reason. There must be a voltage between 120 and 135VDC at these points. Find out the reason for this voltage drop is the next step. The video drive voltages in most TVs comes from LOT windings, after rectification and filtering. There will be one reisitor of low value, say one Ohms or so, will be connected series with this winding, in between diode and winding. Check the voltage at the cathode of this rectifier diode first. If found low replace the diode and the smoothin capcitor. The smoothing capacitor will be between 33 and 47MFD 250VDC rating. Replace both of them. If there is volatge, say 200VDC or so, check whether this voltage comes to the CRT base board or not, If not, check the conducting wire, serial resistors; if used for open. There is no chance of transistor shortage at this time as the raster we see is white. If raser we see have a specific colour predominent, that is green, blue or red, check the revalent video out transistors and replace it. It is best to replace all the three video output transisors at the same time with same batch and number.

Sound but no picture


if the screen is totally black you must need to check weather the heater light in the neck of the picture tube is working. if not, their might be a problem in the horizontal section or the FBT has defect. now if the screen has a white raster like a snow the cause would be a bad tuner board.

KP-61HS30 has sound but no video


1) the problem you have is lack of raster , the problem in tv has 4 phase 1) raster 2) picture 3) synch 4) sound.
2) test the power supply , check the horizontal output +125vdc ,vertical output from +80vdc, +al other circuit +12vdc, if there are missing fix it, see the diagram attached.
3) TEST the signal from tuner,i-f, detector, AGC
GOD BLESS YOU

HORIZONTAL TRANSISTOR BLOWOUT


If the "Chopper" transistor repeatedly "Blows" it is usually because the LOPTy (Line Output Transformer) is faulty, usually a short. OR a shorted Diode or Capacitor, in the driver or output.

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.

What universal remote will work on a ilo television model no dtv2784


This TV is made by Orion, some of the Orion codes may work with it. I had my Dish remote working with it. The mute and video imput functions did not work. If you can get a cable remote 1056B01 made by URC you can do a code scan. One of the codes works for this tv.

If you need the original remote that came with this TV email or call Orion support http://www.orionsalesinc.com . You can also find them on Ebay.

Check the bulbs. If one is burned out, you will get this problem. The bulb is easy to change but will run you about $300.

Pic Bleeding


this sympton is characterized by the presence of red, cyan, green, magenta, blue or yellow colour in a supposedly plain white raster. proper colour reproduction cannot be expected if the raster is coloured. this symptom is caused by a poor white balance adjustment of by a trouble in the CRT, colour amplifier, color demodulation or colour output circuits. if the raster has a tint of red or cyan, check the R-Y output circuits and the first grid, second grid and cathode circuits of the red electron gun. but if you dont know anything about this, just bring it to a qualified service technician. good luck!
