The tuner module is bad and would have to be replaced, the other concern is video 1 and 2 are now becoming snowy, at this point I would suggest replacing the tv set because there are two separate issues and the cost to repair in my view would not be cost effective, cheaper in the long run to buy new tv.
I am sure you had some strong static electricity. The static spark arced to inside of the TV in to the circuit board. Many of the low cost TV sets have poor static electricity protection.
In most cases there is damaged caused by static shock to electronic devices.
Just for curiosity, you can try unplugging the set from the AC mins and plugging it back in to do a simple reset, in case there is no damage and some logic device became hung up.
Last year I picked up my mobile phone and got a static shock from it. I had to get a new phone. This phone never worked again!
Without seeing it I would suspect a bad connection on the main board. As the board heats up the board expands and as it cools in contracts opening and closing a crack in the board. Sometimes a crack or bad solder joint both are sometimes hard to find and it is a lot of solder and wait and see.I have had some luck by tapping on the board with an insulated handel of a nut driver,.. the tv on and watching for any change. If i tapped around the board some areas were more sensitive than others. I then soldered that area. I would tap around again if the set did not react I assume the problem fixed
Most likely your Cathode Ray Tube or CRT is going bad. That model number reflects an older TV. What you are describing is a fairly common problem for that television. If you bump the TV and it improves or gets worse then you know there may be a short.. Either way, I would recommend that you use our Premium Service or use our online resources to find a repair person near you. Good luck.
that sound is comming from the tube anode it is leaking you have to discharge the high voltage from the anode cap,then take off the cap clean the area with alcohol and put some red or clear silicone on the cap and anode connection replace back the cap on the tube leave to dry for about half hour,this will remedy your problem,no more static.good luck.
The power regulators are famous for going bad. The big problem with this TV set is that unless you use the exact regulator from Toshiba, this set will fail time and time again. Even if the regulator IC has the exact same number, it will not hold up. We used to have a shop that was authorized by Toshiba, and we seen this problem many times when customers would say that they had their TV fixed by some local shop and the same problem occured several times. Good Luck
Try hitting the side of the set while you are waiting for the pix to turn on,dont over do it and see if the set reacts,if it does you will be looking for loose conections in the main board or crt board,these solder points need to be resoldered,if you are familiar with tv service it will be something you can do but if not be safe and call for help,the repair should not be expensive right now.
