Re: Why is the pitcher So Dark?
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.

Check resistors in the small PCB connected to picture tube. Check picture tube grid voltages. Check brightness control swing on the IC out put. Note down the IC no and search in the Google for pin configuration.
Are you really sure , your set has video? How dark is it ? As if really nothing visible? Am, sure you can hear sounds. You can adjust the brightness + button to increase the brightness. But if nothing happens , you have problem with your TV set. The problem might be in the Video section. Please let an expert technician to check it. Please don't do it by yourself, it's risky.
Please send feedback whatever comes up. So we can help you further in the future.
Apparently you have a possible component failure with your Panasonic PVQ-2510.
This would involve the circuitry at the back/neck of the picture tube. Diagnosis would require familiarity with discreet components, use of a VOM, soldering and general component knowledge. In as much as it is possible that your red drive transistor (or an IC) would require replacement or resoldering, your best bet is to seek the services of a qualified professional.
Should you venture to do a do-it-yourself, pls post back.
Good luck and kind regards.
You might've done this already, but first I would try the "Magic Focus" The button can be found all the way to the left of the buttons panel on the tv itself. If that has no effect, try playing around with the settings within the tv. Click menu on the remote and see what happens when you try settings like color, balance, and contrast.
