What colour raster it seem like you got the coolling oil inside the picture tube leaked out is typical from Samsung to confirme your problem you should open the back of your rear projector and look if you see any sight oil or liquide on the PCB printer circuit board if yes it require an technician to remove the PCB and clean this oil if not too much damged and install 1 modifications kit if no oil leaked you might have problem in high voltage it call deflection PCB part No.BP94-01259G or L you still need to adjust convergence after replace a new DEF PCB require Technician level 1

Sound but no picture on samsung 51e440a plasma. Experienced tech but new to plasma technology.


You've done a very good and exhaustive check of the TV electronics. It appears that the boards are all doing their jobs and you are getting sound and can control the TV. Do a thorough check of the glass panel with a flashlight. Look for fine cracks, particularly in the corners.

When tv is powered on tv only displaying channel number and sound -no raster. using video mode displays are ok. sound is also ok


Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

Picture tube


what kind of display have, totally black or only a raster?. if you are watching a local channel then only a raster with sound, it could be a tuner problem. now if totally black screen you need to check if the flyback transformer has high voltage coming out at the anode cap. and then the tube has heater light. this case can be hand held with a trained technician if you don'y have an idea on how to deal with it just leave it to the tv technician for safety reason. however at least you have an idea what to expect if you decide to hire for somebody to fix.

Sharp 32'' tv -no raster showing channel numbers only


since you have sound and display it's not the hivoltage. You're electron guns are not being turned on. Most likely the IC which biases the guns or the IC which contains the biasing resistors.

No raster, No sound, No channel number


wepu, Buddy it sounds like you got a power supply problem. As you say the picture is all blue?? With no video or sound and the fact that the channel display is out is the first indication that i would guess this. Do you still have the owners manual that you got when you first got the set? Good, cause thats the only place i can think of where to look in case of service over in your part of the world as I did try!! Man I tryed but to no avail. No one has heard of this model but that dosent mean that it dos'ent exsit!.. If your a tech or know your way around solid state circuitry then you should have no problem finding the fault once you get a service manual from the service location in your owners manual. Now if your not a tech and a handy man ?? If I were you I wouldnt mess with the tv as theres over 25000 volts inside the set and i've seen it make a grown man cry. Man dont attempt the repair or troubleshooting if you dont have the right or proper tools and equipment!!! Good Luck
