Lcd light problm disply


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

In some models of LCD displays; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should be troubleshooted. Contact any service technician. The circuit will differ with models and versions.
Type in the brand name of your device, in the search box [at the top right] of the display window and the Search will start at once as you type in, and will show you all the related posts. It will make surf easy.

How do i change bulb in tv


Hello
Your Samsung tV is LCD type. It has no bulb to replace as in DLP projection televisions. there is CCFL [Cold Cathode Flourocent Lamps] are the lighting devices, which are fitted just behind the LCD screen There will be more than 12 numbers of them, accroding to screen size. If these lamps do not light up; that is; if you do not get any backlight with your LCD TV, the backlight inverter board should be troubleshooted. This is the board that supplies high frequency high voltage to these lamps to light up. Check this inverter baord first. Repalcing backlight CCFL lamps is really a skilled work, as they are fitted inside the panel, and to replace them, you have to disassable the panel itself.

My LCD model L1510S ,problem is the lcd light not wrking. starting time light is coming after 5 seconds light is going


Hi,
The problem is the inverter in the LCD monitor.
If you have experience in replacing parts inside that LCD monitor, you could repair it by replacing the capacitor on the inverter. If not, you have to bring it in your nearest technician to have them repair it.
Additional info in actual repair could be seen in YouTube( type "LCD Repair" ).
Hope that helps you out!

Monitor black Replaced lcd inverter


Hi,
The Inverter just proved that the power up is just fine, and Video Card are just in perfect shape. Try to see if you can finde a replacement for the ccfl in the screen.

CCFL is Cold Cathode Flouroscent Lamp, a type of lighting LCD screens use to ulluminate the screen.

Try to turn on you laptop, you will then flash a light on the screen, you will notice there is display, only dimmed. This should work after you replace them just fine. :)

Projector lamps


Good Day,

You are correct when you say it produces a brighter light for their size.

According to the training meetings, all manufactures, they will replace this type of lighting in the future. Samsung already has on their newer units with led/lcd type lamps.

DLP's/LCD Projection TV's need a very bright light to project the image.

Good question.
