#021 pattern generator for LCD | Led TV Repairing | RT809f ISP Programmer



Published
This TV pattern generator RT809f ISP Programmer is useful for fault finding in TV sets and in LCD LED TV sets too. You can correct the alignment of the timing circuits of the TV set with the help of this Pattern. The Horizontal stripes (Lines) produced by the pattern generator on the TV screen help you align the Horizontal scanning synchronisation circuit of the receiver.

To test the TV set, you need to connect the video and audio outputs of the circuit to the respective inputs of the TV set one by one. If the video section of the TV set is working the circuit generates Horizontal stripes white lines on the TV screen, and if the audio section is working you hear sound from the TV’s speakers. You can also adjust the width of Horizontal lines.
