Lcd screen too reddish

I recently replaced several capacitors on the power regulator of my MAG 19" lcd monitor as it would not turn on. It worked awesome for a few months, but now when it is turned on it has a severe reddish tint to it. Any ideas?

    I forgot to mention that it started at first by beginning as reddish then it would settle into a more normal mode during boot up. Now it is constant.

Hi

Have you tried using a diffrent power socket as ststic can also cause this to happen. Use a power socket with earthed connection. Also check the HDMI cable and change them. If you are not using HDMI cable then try using it and see if there is any diffrence.
Also check if there are any speakers or a cordles phone kept near your monitor.


Please do accept this solution and revert for further assistance.

Thanks
Rylee

Your LCD has something bad but some solution is provided here :
sounds like your LCD backlight has blown. if you shine a bright torch against the screen can you see images on it? if yes then it is your back light.

if on the other hand there is no image to be seen then the problem will lie within the wiring connections between your LCD and the motherboard and graphics. could be that a wire might have become worn and therefor broken off.

LCD monitor works on RGB, if color is red, you have lost blue, green or both channels. This can happen because of a bad video cable, then double check.

If the cable is OK, then test the ribbon cable to LCD, and the input signal board, where you connect the video cable.

If you do not find anything in there , then it is usually the LCD controller board, in that case you usually replace it after testing, as troubleshooting and repairing a complex board like LCD controller may be difficult.

You find parts for several monitor here : Replacement Parts: Plasma TVs, LCD

Alternatively order parts from manufacturer.

Standby light stays on and does not allow me to turn screen on


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

Have a Mag 19" monitor, model LT916s. Screen is


Sounds like a silly question but have you checked the fuse? If it isn't that then it sounds like a problem with the power board. Check it for burn marks and bulging electrolytic capacitors (they're the little round tube like things that stick up), also check any fuses on the board. If it's the caps or a fuse then just replace them, if something else is burnt out then you'd have to replace the board but you might not be able to find a replacement since it's old.

Screen goes black but power light stays on


Hello. I had the same problem with my X2gen 19" (model MW19R)monitor. In my case, the monitor would turn off after 20 seconds or so but the blue power light would stay on as well. I had to replace a high voltage capacitor located in the backlight power supply board. There are 4 blue capacitors on the board which are identical and they are marked as 27J 3KV. Fortunately, I only had to replace one of these capacitors ( it was turning a yellowish brownish color ). Hope this helps.

Black screen


It is most likely that the filter capacitors on the power inverter board have failed. I took mine apart and found seven swollen capacitors on the this board, they fail prematurely and seem to be the only thing wrong with the unit. I replaced them and now it is working just fine.

six 470uf 25v electrolytic capacitors and one 220uf 25v Capacitor.

you should not attempt to repair this yourself unless you have some electronics training since there is a shock hazzard involved and also these capacitors will blow apart if they are installed incorrectly (very messy experience).

Dead monitor,,,,,,,,,,,,,,,,,,,lcd viewsonic


If the power supply is not wqrking then it is the invertor unit that has dies.
Replace the monitor is the best advice- If it that recent out of warranty may be worth contacting 'viewsonic to see if they will discount you one.

Hi..there,
The lamps has nothing to do with it... what you need a new backlight inverter or repaired it by replaced a couples of bad capacitors... Sound easy... right! Not so... It's not always the caps problems.

Monitor went Blank / Black (MAG Inov...lt916s)


Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!
