Re: ok from the back of the tv!!
I am at work where I do online tech support for servicemanuals.vstore.ca customers so I dont have access to a remote but if you look on the board that has the 4 large red wires
Look for a black IC with 9 pins it will have the numbers TDA36540 stamped on it and the board location will be 7555

You need to give more info. Try putting you tv set to channel 3 or 4. Try your tv in all modes. Check the back also to see if in the right spots with the wires. Check your channel scan status, try it on anntena and try it on cable, run channel scan on both. good luck. Try vcr wires if cable wires dont work. vcr wires are yellow red and white. Try another cable cord sometimes they get old. Try looking at your remote and setting it to tv.
This is generally the case when the Horizontal Yoke Coil is defective.A defective Hor. Deflection Coil bad is very very rare. 9 cases out of 10 it is a dry / bad solder.If you are versed in Solid State Electronics, I advise you to Unplug the TV and carefully open the back panel. There will be a Coil mounted on the neck of the Picture tube. It will have 4 connections and there will be 4 wires leading from it to the Main PCB. Check these connections - both on the Coil and on the Main PCB.
If these are OK, then call in a qualified Technician.Nothing more you can do.
The noise is coming from the fly-back transformer. By moving the cable connector you move the main board. Unplug the TV and remove the back. The transformer has a red wire going to a rubber cup at the top of the picture tube. Looking at the transformer you will see a dough nut shape with a metal piece going through it .. Drive some tooth picks between the dough nut and the metal core. That should reduce or stop the ringing.
i had the same problem with my tv i got a sodering gun its the board like the power supply open the tv and look on the board and look for ic801 on the bottom of the tv board then look in box line it has numbers from 1-7 get a sodering gun then soder number 4 i tryd it it worked on the board but be care full it will mess up quick if your not i had the same problem with this tv the soder on the board probly came off on no.4 but after your done and you have to pick the tv up becareful and do it slow because number 4 might come off again then you have to do it again and if that aint it just look on the bottom of the board and make shore nothing is loose and use the sodering gun to put back on that should be it ok then
ok this is a bit complex but im going to describe to you what you have to do\
1) TAKE THE BACK COVER OFF
2) LOOK FOR WHERE THE SWICJ IS LOCATED
3) LOOSEN THE SCREW WHICH HOLDS THE BUTTON
4) CARRY ON LOOSEINNING BUTTON UNTIL YOU CAN PRESS IT
5) THEN CHEC IF IT WORKS IF IT DOES TITEN THE SCREW AND PUT COVER BACK ON IF NOT THEN CONTACK ME
Ok your going to need a VOM meter and a soldering iron (25 to 53 watt, not a soldering gun). By no sign of power Im guessing that there is no click or any kind of "electronic" noise from inside the set. Ok, safety first, unplug the set and once you open it stay away from the high voltage anode wire that goes to the CRT (picture tube). In side by the power supply locate a resistor that should be at location R607, it is colored white and has a value of 0.1 ohm. It is most likely open, if so then most likely Q601 and Q602 are shorted as well, you will have to replace them and it is very important to also replace the following (shorted or not) R644 6.8ohm I think 1/4 watt and VDR601 VDR602 and VDR603 One of them is color black and the other two are green. I think VDR601 is the black one but dont quoat me on that. Next go to the Flyback transformer largest transformer in there (roundish in shape) near it is the Horz out transister I think it is location Q591, check with your VOM to see if it is shorted, if so replace it. Once you have that done solder the pins on the flyback and the Horz drive transformer, again dont quoat me but I think it is location T503. If you have a ESR meter check the electrolytic capcapscitors.
Hope this helps! Good luck!
When you have the back off, look for the flyback (high voltage) transformer. This is the part that has the thick red wire protruding from its top which attaches to the top of the picture tube with a suction cup. On the flyback there are 2 controls, the bottom one is screen and the top one is focus. Turn the bottom control (screen) down (counterclockwise) until the white lines go away and the brightness looks normal. Then turn the top control (focus) until the picture is nice and sharp. If the F connector has been pulled out and the TV has RCA (red, white, yellow) jacks, use those jacks and set the TV to INPUT.
Did you change the resistor by yourself? I am not sure if your TV has manual adjust on the back of the TV that you can adjust. Some times turning the TV Off and unplug it from the wall helps because it resets the TV. Check your Back ground color and see what is the dominating color. Blue, Green or Red. If this doesn't work please call a professional to look at it.
