Question about Televison & Video
The picture is to dark I canot get it to lighten up
If the TV is the conventional CRT type, normally, all you would need to adjust would be the brightness level and occasionally the picture (contrast).
In some instances when both settings are at the maximum but the picture is still dark indicates a hardware fault inside the TV. Often, this would be a simple resistor that has opened up in the G1 or G2 located at a squarish PCB at the rear of the CRT. This is relatively an easy repair job and low cost.
The worst possible scenario, this could possibly be a major component failure such as the tube itself or some other part(s).
Should you venture a DIY, you would need familiarity with electronic components and circuitry, use of a DVM and a soldering iron as well as access to a service manual or at the very least a schematic diagram. Should you be uncomfortable going this route, perhaps your best bet would be to seek the services of a qualified professional.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
