Cable from cable box into tv. tv goes to blue screen. works if cable is jiggled at tv, but then picture starts going snowy and then to blue screen again. seems to be intermittent. Opened up tv and can't visibly see any problem with the connection. Cable connecter in tv is soldered to circuit board. Good tv otherwise. Can't afford new one.

Looks like
1. A Cold solder in the Video Output stage power supply.
2. A bad Electrolytic Capacitor in the above Video Output stage.
I generally do not waste time in attempting to locate faulty capacitors. There will be only 6-8 pf them in the above stage / section,m and the klot of them would collectivelyt not cost more than 3-4 $ equivalent, in india. Just blindly replace the lot, and the set is ready in 30 mins.
Dunno how much they will cost in your country. Try to look for a 100mfd, 160V Capacitor. Close your eyes and replace. generally does the trick.

I had a toshiba like that where the digital convergence didn't get close enough. Worse case scenario - remote the screen and loosen the red crt (don't loosen lens for there is liquid coolant in there) and put a couple washers under it and reinsert the bolt or screw. Worked for me and saved a TV from the landfill!!

i am not sure these is going to work but give it a try. after useing the tv for a long time you can get a problem with the lineing of the three picture colors may drift away from each other causeing the problem you have, they move because of moveing the tv or the viberation of the tv. you can to one of two things if you have a remote for the tv go to the menu and look for the convergence adj. setting then you are going to get close to you tv and press the small but the says the same thing now on the screen you are going to see a grid the you can fix youself with the remote just by pressing the up, down,left, rigth buttons and the menu button to change the color, to aline the red line and blue line with the middle line till you get only a white line going up and down if the doesn't work just unplugg th power cord and what for about 4 hours and then plug it in and turn it on again. if after you do all these if you still have the problem then you either have two choices call to see how much it will cost to repair it or toss it out and get a new one
