LG 45V model

28-02-2007

Dear sir,

I have LG 45V model monitor.

Problem was Characters and video both vibrating and sine waves like both sides of screen. I have changed 150 uF / 400V capacitor in SMPS. Vibration problem was solved, but new problem starts that black lines/bars moving from top to bottom. If I adjust Voltage adj. port VR901, Black lines goes but Shhh... Shhh... sound starts.

Lines increases with sub brightness adjustment or screen voltages changes from FBT.

Pl. guide me,
Thanks,
Atul

Generator burning my electronics up


take you generator in and have the output tested for correct voltage and sine wave configuration
electronics rely on a perfect sine wave ac current as a manufactured sine wave affects electronic components such as capacitors, transistors and diodes
generator sets that run an alternator ( not an inverter ) have a pure sine wave and have less affect on electronics.
go google and type in search headings like ---sine wave, inverter sine wave, sine wave affects on electronics, alternator operation and inverter operations and then you may get a pointer as to why your inverter gen set is affecting your electronics

Your monitor supports a maximum resolution of 1280 x 1024. If windows fails to give you the option of changing to this resolution and those below it then please follow these suggestions:

Update your video card drivers, if you don't know the manufacturer of your video card try windows update.

Install the latest drivers for your monitor as well.

My husband hard wired an inverter for our RV to run the TV & associated equipment. It powers them fine but the reception has lines and dots running through it when on the inverter. We purchased a sine...


It is becaus the inverter erradiate EMI (Eletro Mechanical Interference) and the EMI is picked up by the TV antenna, try moving them a part as far away as you can from each other (the inverter and the TV antenna), there are also some filters you can pusches, but enven with all that stuff you could end up with EMI any way so don't spend to much,

Good luck!

The manual states when running on AC, it is the same sine wave ouptput that comes in. When running on DC, it is a modified sine wave.

Is true sine wave better than modified sine wave.


I'm not sure what the application is but I will offer the following. As a retired electronics engineer i can say for sure that a true sine wave does not have any harmonics in it. A modified sine wave will have some harmonics and other what I would call " trash content" depending on how it is modified.

Out of range


Try lowering your refresh rate from 85hz (or higher) to a lower value around 70hz.
This usually will correct out of range issues.

Monitor problem


Your request for the exact problem will require a signal injector and use of an oscilloscope or even more test equipment. One possible cause is the contrast set to minimum.
