The utility model discloses a circuit for eliminating a shutdown bright spot of a CRT display. The circuit comprises a line sweep circuit, an oscillight, a red signal amplifying circuit, a green signal amplifying circuit, a blue signal amplifying circuit and a video decoding chip, wherein the red signal amplifying circuit, the green signal amplifying circuit and the blue signal amplifying circuit are used for respectively amplifying red, green and blue signals and sending the signals to a KR terminal, a KG terminal and a KB terminal of the oscillight connected with the circuits, the video decoding chip is used for decoding video signals, the red signals, the green signals and the blue signals are output from an R pin, a G pin and a B pin of the video decoding chip respectively, an HOUT pin outputs line drive signals to the line sweep circuit, an RGBVCC pin is connected with a drive power supply of the red signals, the green signals and the blue signals, and an HVCC pin is connected with a drive power supply of the line drive signals; and a control grid G1 of the oscillight is grounded. The utility model not only achieves the ideal effect of complete blank screen after the shutdown which is identical to cut-off bright spot elimination, but also decreases part of circuits, thereby lowering the material cost and the computer plug cost.
