When the power switch is turned on, the red power light blinks but the picture doesnot come on the screen. Please tell me what the problem is and how much it may cost to fix it. Thanks.

Re:
The symptom is usually caused by a breakdown in the power supply circuit. in most modern receivers (transistorized and/or ic), it may also be caused by a breakdown in the horizontal deflection circuits (hor. oscillator, pre-drive, or drive circuits). supply voltages for the tuner, video if,sound if, and vertical output are usually supplied by the horizontal output circuit. but if you doesnt know anything about these stuffs, better bring it to a qualified service tecnhician.
i cannot tell you the cost to fix your tv coz my location is in the Philippines.

The blinking light means almost 100% that the high voltage circuit has failed. Probably need a new horizontal output transistor and flyback. Perhaps an associated resistor or diode. If you have the expertise go for it, otherwise take it to a professional. In any case be extremely careful and safe. Good luck.
this problem would be in your power spply or the sweep derived power supply. probably a bad capacitor or regulator IC/transistor. Unless you know how to trouble shoot electronics them please have this set looked at by a pro. Good Luck
