How to Replace Lamp on Mitsubishi TV
A TV Lamp is a type of fluorescent light that comes with the TV set. The lamp generally lives for the life of the TV set. Normal TV life is 10,000 hours of use. It means that the light must be replaced after 10,000 hours.
When the color bars appear to look like rainbows or there are dark patches on-screen (blocking a portion of the image) at any time during operation – Replace the Lamp immediately as it is likely you have already passed 10,000 hours without replacement and therefore will continue getting worse until it fails to cause picture failure and possible serious damage to Television Set which may include possible startup problems etc. In this article, I will discuss how to replace lamps on Mitsubishi TV.
Features and Functions of TV Lamp
- The lamp is used to illuminate the whole screen to produce excellent picture quality.
- The lamp provides optimum color balance on the screen. Therefore, it plays an important role in producing images.
- The LED backlighting in this TV provides for a better contrast ratio, as the bulb glows brighter or dimmer depending upon the incoming image signal level from your device/display card. This results in crystal clear pictures without any distortion or noise, unlike CCFL-based LCDs used in some other brands of TVs where text may have slight blurriness around edges due to incorrect illumination caused by the wrong polarized CCFL voltage being applied for their panel.
- The lamp comprises a fluorescent tube that converts electrical energy into light. It is called a cold-cathode fluorescent lamp.
- It also requires a steady and stable power supply for long hours of operation while playing movies etc. Also, it does not require lifetime replacement like in the case of CCFL-based LCDs.
Why Does the Lamp Need to Be Replaced?
As you use your TV, the lamp slowly loses brightness because of usage and time, which results in the darkening or dimming of images on the screen over a few months. So it is necessary to replace your TV’s lamp after various periods of usage depending upon its brand/model/age etc.:
- For most brands, a typical lifetime of a TV bulb is 1000 – 1500 hrs (which means 1.5 – 2.5 years for 8 hrs/day viewership). But it might also depend on the brand and model of your TV. For example, a new LED TV can have a lamp life of up to 25000 hours which is 5 – 6 years for 8 hrs/day usage!
- If you leave the brightness always setting at Full or 100% all the time (correspondingly decrease its contrast settings) without reducing brightness manually from time to time along with day-night light changes etc., then it may reduce its lifetime sooner than expected because of high temps, as well as the use of bright screens, harms any lamp faster than low temp and lower screen background lighting conditions;
- if you view programs mostly through cable TV signal (cable operator box) or using DVD player, VCR, etc. with higher color settings, then it may reduce the lamp’s lifetime faster than expected because of higher colors as compared to normal programs;
- If you use your TV for watching movies mostly during late-night hours (10 PM -12 AM) and/or don’t dim the screen brightness manually from time to time during the daytime, then also it may reduce your lamp’s lifetime; d) Also if you use your set for gaming or PC viewing most of the time then again it can reduce its life due to more usage, high temps and brighter screens.
