LG PJ350R how to have better contrast brightness etc. thanks

Check out your menu for color intensity, tint, brightness, contrast, etc.

Select menu, display settings, select brightness/contrast/sharpness etc. and adjust these to your likings.

Hi:
You may have a problem with the inverters in the unit, they are responsible for lighting up the back panel. Check or have checked the power supply voltage to the inverters, should be around 18-24 volts DC. Also leaky capacitors on the power supply will cause this issue as well as leaky or puffy capacitors on the inverter.

Dear amy mcioynt,

Welcome, and thank you for using FixYa!

The issue you describe it caused by the video board going bad. All of the controls for video display, clocking, brightness, contrast, and input source is handled by this card.
They are replaceable, if you have the part number. Most of the time they range from $50 - $75

Have a great evening!

Hello
Adjust the contrast to 55 to 70%; brightness to 45 to 55% and colour to your viewing taste. Now the brightness will be very low I thinks. Advance the brightness and contrast after setiing the colour to Zero. Adjust for a well defined B/W picture first. The advance the coulour. Take reference of the face colour of a news reader at studio. The picture will be perfect. OK.

It's time to RESPONSIBLY RECYCLE any 17-inch CRT monitor, and buy a LCD monitor;
used LCD monitors can be purchased for under $50.

It would cost you over $50 to take the CRT to a TV/Video repair shop, for trouble-shooting and repair.

On screen menu should have brightness and contrast, and other adjustment.
You can get user manual here:

The supplied software should allow you to set brightness and contrast if there are no front panel buttons to set it.
Check for LG or Flatron programs under the Programs listing available from the Start panel.

there is sometimes a subtle change in highlight when you have selected the brightness (or any manual change menu selection) you should then be able to make changes to the selection via the up or down buttons on the monitor

Sorry it's a fault :( You can try to open the monitor and reallocate the buttons making sure that they are not stuck to the receiver,if that is the problem you will solve it. If the receiver itself is faulty,however, better get a new monitor. Of course if the monitor is still in warranty you can call LG's call center.
