The TV picture became about 5 cm less then normal on the top and 2 cm on the right side of screen. It became gradually. Looks like some kind of capasitor has been loosing its capasity. TV set SHARP 70GS-64SC quite old but the pcture is OK, without the problem discribed here above.

Re: SHARP TV SET
Check the power supply circuit. Typical voltage at B+ is 105V. Chances are that it is much lower. Check (as you say), capacitors on the primary circuit of the SMPS. Better still, replace all low voltage capacitors within the power supply.

You can go to TV 1 to make sure TV 2 is suppose to be set to channel 60. Did you run the auto setup on your TV? If you have already run the auto setup on your TV, unplug the receiver from the electrical outlet for 10 seconds and then plug it back in. This will make the receiver reboot and re-acquire satellite signal. Then see if you get a picture on your TV 2. If not, the last thing you can try is changing the channel from 60 to 73 through the receiver.
With your DISH remote at TV 1, press the Menu button - Main Menu will display on the TV 1. Then press 6 (System Setup), 1 (Installation), and 5 (Modulator Setup). On the Modulator Setup screen, move over to TV 2 Out and select Cable, then press select on the remote. This will automatically change the channel from 60 to 73. Highlight Done on the right and press select. Cancel out of each screen till you get back to the TV screen. Go to TV 2 and put the TV on channel 73. You should get a picture. I hope this helps.
A good tech can find out what is wrong with the set. The power supply has a protection mode which causes the shutdown. Also, there is a memory chip that a Sharp repair center can connect to and read out the fault history. A shop that talks about replacing a board is not a good place to go to. You need a shop that can isolate the malfunctioning parts and replace the part at the circuit level, not at the board level.

Pls rate my suggestion.........
I think you mean ' switch ' and ' only the red light ' ( power ) comes on.
It could be an internal trip on your tv set that needs looking at by a tv engineer ( normally parts required ) or if you have a tv with a ' factory settings button ' on it ( normally on the side or top if it's a flat screen tv ) press and hold for 10 seconds then the intial ' tv setup ' will appear on the screen ; after that, just follow the guide.
Hope this helps.
It depends, the center line you speak of, does it go from side to side? Or top to bottom? Side to side you have problems in the vertical circuit. Top to bottom you have a problem in the horizontal circuit. Not picture tube problem. If it is an analog tv and depending on how old it is. What an estimate and the actual repair would be you are better off buying a new one.
I too have an Aurex TV ..and have to adjust the screen size regularly .I do this by the hand control.at the bottom of the handset are two rows of buttons..3 on the bottom row and 4 on the next row up..the on furthest on the right on the row with 4 buttons is the button for screen size change.
Did the cable person take a reading on the signal level at the cable outlet on the wall and did the cable person check the TV setting to make sure they are correct. TV could be set on the wrong channel also.
Witch part of the screen you loose?if is the bottom or the top it could be a problem in the vertical IC circuit if is the left side or the right side is a problem on the horizontal deflection circuit(very rare),try taping on the set when it does it and see if the pix reacts ,if it does one way or the other you have loose conections and some resoldering need to be done.If you are familiar with tv circuitry you will have no problem.If you are not be safe and call for help.
