Fading screen


If you're seeing a shadow either vertically or at an angle the most common/probable cause is the light tunnel in the light engine. I have this same problem with my ru-44sz51d and have found many people with similar problems. For reference search "dlp light tunnel" as many samsung dlp's are suffering from the same problem and have been since they were purchased. You should be able to repair this yourself, but only if you feel comfortable and are knowledgable in such a situation. The repair may consist of replacing any number of the 4 or so mirrors or just reapplying the silicone adhesive to the original mirror. As I have not done this yet myself I can only speculate and refer to topics I've read about. Good luck

Shadow down left hand side of screen


Is it an LCD or DLP? The Model below suggests it is an DLP. Sounds as if you have the dreaded light tunnel collapse common to all LG DLP TV's. Inside the light engine there is a square tube made up of four mirrors. These mirrors deform and crack with the heat of the lamp. They fall down over the light aperture and cause a shadow of varying degrees. It is fixable now at a realistic price ( used to have to replace engine) as LG have made the parts available. It would take a competent tech around three hours to complete or if you are technically minded you could do it yourself. I hope this helps. Good Luck.

Lg plasma flatscreen


Hi,
The boards responsible for sending signals to your plasma screen has gone bad. Technically speaking, the Y SUS, Z SUS and the Y Buffers are suspect. Sometimes, owners heard a popping sound then the display will go away leaving only sound. It's an expensive repair that can go upwards of $500. Fortunately, LG typically has two (2) years parts and labor warranty for their big screen TVs. LG has a strict repair turn-around time so call it in and you'll have your TV fixed in no time... (realistically, 5-7 days). Best Regards

Proview pl926wbi 19 inch monitor case removal


Hey Bob,
I just did this and the following worked for me.
1. Orient the monitor so the base is facing towards you and the top is facing away from your. Make sure the monitor is LCD up.

2. Grip the gray plastics just above the buttons and flex it up and towards you. You should be able to see the button control panel.
It should flex enough for you to rest the bezel and screw holes on top of the underside bezel. When doing this you have to wedge your finger tips between the LCD panel and the gray plastics to separate it. The trick is not to apply too much pressure to the LCD panel itself so you don't damage it. Almost all your pressure should be applied to the gray plastics as you lift "upwards" away from the LCD.

3. Once you have done this, you need to slide the bezel away from you towards the top of the monitor in order to release the side tabs and the top tabs. I found the best way to do this is to push upwards or away from you along the bottom left and right corners of the monitor and move upwards along the side of the monitor.

4. Once you have release the side latches the whole bezel should just slide upwards or away from you.

Note: When replacing the bezel you need to start from the top and insert the top tabs first. Then align the side tabs and last align the bottom button portion of the bezel.
