Picture too dark

The picture is too dark. Is there a "brightness" adjustment or is the set just getting old? The only possibilities I see are on the back (Tech adjustments) "Screen" & "Focus". What does "Screen" do? Thanks

Brightness Problem

On some of the hitachi's the spark gaps will get dirty and cause this, they are located on each crt board 2 on each they are small white and retangular, remove the caps and spray tech cleaner into them and wait for a long time before plugging the set back in, see if this fixes it, if not then you have somting else going on. If you don't have any experience with electronics i would leave it to a pro though.

Adjusting darkness

Hi Angel,
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.

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.

Good luck and kind regards.

Thank you for using FixYa.

If you promise not to touch the wrong thing, you can adjust the screen and focus knobs on the high-voltage transformer (what we call the flyback). Do you see the big red wire going to the CRT tube? That is the anode lead of the high voltage (around 25,000 volts). The thing that it goes to on the circuit board has 2 little knobs coming out the back of it. Try adjusting those (use a tool with insulated handle if you please) to increase the brightness and improve the focus. When the screen adjustment is all the way up and it is still too dark - then its time for a new TV.

Picture suddenly went dark

Hi, 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.
