SOURCE: brightness sometime too light and sometime too dark

I would say there is a problem in the horizontal / high voltage section, but I have no information on this model.

My LG 700E crt monitor has stop functining to control brightness and contrast ,Any other way to increase or decrease brightness and contrast. pls let me know thanks


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.

The brightness/contrast window pop up randomly and frequently. Brightness level keep on increasing automatically. Pls help.


A 15-inch CRT monitor? It's time to responsibly recycle it, and buy a 17-inch LCD monitor, because _nobody_ fixes CRT monitors any more.

bcollier696, You did not state how many hours of use this small screen monitor has on it!! You may need to replace the CRT if it has been in use for a long time. Can you approximate the total "ON" time of said unit? Is it >10k hrs. Multiply hrs/day x 300 days x yrs of use. If u come up with 15k hrs or more replace the unit with an LCD if possible.

Snowy Raster on display


Hi mcuyg,

Hope this will give you hint in solving this problem. Try configuring monitor settings in OSD mode; contrast; brightness; etc.. other special settings can be accessed using combination of buttons to minimize the raster intensity. On hardware side try resoldering cold soldered points and check the SMPS side.

Best regards,

Check TRC heater voltage (6,3 V., pins 3-4 of TRC socket counting counterclockwise) when picture goes off; if there's no voltage but it appears when picture comes back, look for bad solder joints tracing the circuit backwards to the power supply. Usually, the 6,3 V. tension comes from a single diode-electrolitic cap circuit at the secondary of the power supply transformer.or check this
Pin assignment for a monochrome 9-pin D connector are:
1, 2: Ground
3, 4, 5: not connected
6: intensity control (contrast)
7: video signal input
8: horizontal sync.
9: vertical sync.
Video monochrome cards usable are:MDA (monochrome display adapter) HGA (Hercules graphics adapter) -Some CGA (Color graphics adapter) and EGA (enhanced graphics adapter) cards that have a switch mono-color can also be used.
