Question about Akai CF2791 27" TV
I have sound but no picture,picture flashes for second then go's out can you tell me whats i need to do to fix my t.v.
This may be a problem in the HV section of your TV. My question is do you have raster, or is the screen totally black? If you have raster then this is a video problem, if the screen is totally black then it is a HV problem. In either case if you do not have a background in electronics I would suggest that you take your TV to a qualified TV technician. If you do have a background you will need the following items:
A schematic diagram of your TV set to know where the test points are and to see what voltages and or signals should be at what point in your TV set
A multimeter to measure AC voltages. DC voltages, and Resistance when needed.
An Oscilloscope to measure signals that should be present in various sections of the TV as shown by the schematic.
A signal generator to create the proper input signal for testing.
These are the major tools needed, not to mention a soldering iron, and a de-soldering tool
I hope this helps you,
