Repair lcd

If the lamp is broken of course - replace it. Otherwise a bad lamp will still light. It just won't be a nice white color. More of a reddish orange, only lit on the ends or flickering just like any other fluorescent lamp. You can, of course, try to measure the output of the inverter but with the loading effect of the meter/scope and the fact that it's a high freq AC output I wouldn't know what to look for. Lamps are only about $10 so that's where I start. Even if it doesn't solve the problem you can still charge the customer, you just tell them there was no sense putting a new inverter onto an old lamp so you replaced it while you were "in there". I personally wouldn't want to warrantee a laptop with a new inverter and a used lamp. If it comes back next month with the old lamp burnt out you'll be replacing it for free under warrantee. The customer doesn't know invertors from lamps so they'll assume because the display went black last time and the symptom is the same that you'll cover it. Lamps and invertors can both be had from JKL through Digikey. The biggest problem with invertors is their physical size and mounting holes. I read the warrantee card on a KDS LCD screen a few months ago, in fine print down at the bottom it said that the lamps AREN'T covered by the warrantee. This means that if the lamps go out while it's under warrantee the unit goes to an authorized service center and they change them but they get to bill the customer for the work. This may increase the revenue of those that are authorized because they will now get paid for a lot more units by the customer instead of KDS but it's also going to make for a LOT of very unhappy customers. I currently get $135 Cdn to change the two lamps in an LCD. We always change both, no cheapskate onsies thank you very much. Lamps are about $10US - $15Cdn ea so labor shows $100 which is comparable to what I used to get for a monitor repair. My advice is to go to the places that sell these and get in touch with the manager, show/explain to the manager that the lamps aren't covered and that if his customers come in with this symptom they will be better served by sending them to your shop for faster service. A lot of the big box outlet stores take the returns and send them off to a depot. This could leave the customer without his unit for up to a week and they'll still get a bill. In the next 5 years a lot of these will be failing, the lamps only last a couple of years if left on all the time. Although I strongly disagree with the idea that LCDs will replace the monitor any time soon (read in the next 10-15 years) I don't let opportunities slip by either.

no picture on my samsung 61" dlp.

The color wheel if bad enough, will cause the lamp not to light. If the lamp is truly bad, you can't usually tell by just looking at it unless of course it is broken.

pictures reddish or orange

Although normal room lights (tungsten lights) appear white to our eyes, their light is actually much "warmer" than daylight, giving a reddish or orange color to pictures. This happens with digital and film cameras. To prevent or lessen this reddish or orange color: If your digital camera has a selectable White Balance mode (check your camera's User's Guide) and you are not using the camera or external flash, set the White Balance mode for "Tungsten" light. If your pictures are reddish even when you use the camera flash or external flash, the room lighting is overpowering the flash. Try setting the White Balance mode for "Tungsten" and continue to use the flash. If your camera does not have a selectable White Balance mode, use the camera flash or external flash when taking pictures in lighting that makes your pictures turn out reddish or orange. If you can, turn down or turn off one of the room lights (without making the room too dark), or move your subject so that it is not being hit directly by the room lights. If you can, when taking pictures in the daytime, try opening any drapes that might be covering windows. Letting in natural daylight improves the color quality of the lighting.
