Sharp sheo only reed light model21Q-FG1F
Not many easy answers: set is having either power supply problem or a problem in the high voltage area.To be honest a repair in a set of this size and type could cost as much or more than a new set would cost.
Hi I have a 27
hit your TV lightly on left side or right side or on top & then observe ..........you will get normal picture or it comes & again it goes....if it is happening like that then following is the situation..........after 4 or 5 yrs in some TVs on main board ( also on CRT circuit board ) at some soldering joints crack develops....then due to loose contact picture becomes small in size or abnormal width, or rolls etc ...........when we hit that lightly then those loose contacts joins temporarly & again picture appears normally for some time............so solution is .....TV main board & CRT circuit board should be observed carefully & most of the joints should be re-soldered.......only a good service engineer can do that........even after hitting TV lightly if there is no response then main board has to be checked completely........in your case iam sure it is loose connection problem.........joints should be re - soldered ...100% it works again ................this problem cannot be solved by user unless user has idea about components( resisitors, transisitors, diodes,...etc) , have soldering iron , multimeter & other tools....................so contact good TV service engineer .............iam from bangalore - 09986222774 - [email protected] ( computers, laptop, printers, etc ).

Contact Switches are either dirty or bad and need to be replaced the ones in front of TV vol- vol+
first try cleaning them with contact cleaner all of the Front contact switches.
Upon initially turning on power
Hello,
The television is having a power problem, that is why it is no turning on, it most likely is as a result of a bad capacitor on the power panel of the television.
Have the power panel replaced the assess the main panel for any problems.
Take care and good luck.
Also check the sound ic, it might hsve been burnt due to some bad power problem.
