A few days ago, I heard administrative colleagues say that they are going to update the projection equipment in the conference room. The colleagues who have been tortured by the old projections can’t help but rush around. Shouldn’t the old projections be thrown into the waste pile?
Before our meeting room, we used a Sony VPL-EX130 business education projector that was released in 2009 and purchased that year. Its 3000 lumens brightness allows us to see the projection screen clearly without turning on the lights in the meeting room, which really helped us complete one. Another meeting.
In ten years, the brightness of the new products of that year has gradually become lower, and the resolution of 1024*768 is not in line with the current mainstream 1080P display. When I saw this Sony EX130 with dust on the bottom due to hoisting, a bold idea came to my mind-I want to return it to the battlefield!
The biggest problem with old projectors is the aging of their bulbs over time. Although the decrease in brightness can be solved by reducing the ambient light for a while, in the final analysis, it is necessary to change the bulb. In the summer, the scorching heat and buzzing noise of the Sony EX130 makes it difficult for the participants to start a brainstorm at the same time.
What is the projection that has been used for ten years?
I believe that many netizens’ companies have such a long-used projection product. Over time, the dust on the fuselage gradually increases and the brightness decreases.
Our ten-year-old Sony EX130 uses a ceiling-mounted projection method, and its top is basically kept clean, and the bottom is heavily dusty.
Connect to the computer and turn on the projection, we can see that the brightness of this ten-year Sony EX130 can no longer meet the needs of general meetings, and it has a color cast.
Through the side and front noise tests, we can see that the side noise of this ten-year Sony EX130 reaches 57.8dB, and the frontal noise reaches 68.4dB, which can be said to be very "noisy".
What do we need to refurbish the projection?
Let's first summarize the current problems of this Sony EX130 that has been used for ten years. The first is the brightness of the bulb, and the second is the noise. So how to solve it?
For the problem of bulb brightness, we can easily find the bulb of this product from the Internet. After all, Sony EX130 has been discontinued for more than five years, so we had to choose a bulb from a third-party brand.
The noise of projection products is mainly caused by the congestion of the filter and the accumulation of dust inside the fuselage. We only need to replace the filter and clean the dust inside the fuselage after disassembly.
Just do it! Let the ten-year-old projection return to the battlefield!
When I bought the bulbs online, I found that I also presented a dust-proof filter, which saved me a lot of energy.
Everything is difficult at the beginning. Let's start with the simple things and replace the dust filter at the bottom of the fuselage. Because of the "concave" design, we need to cut the new filter sponge according to the ed
ge of the original filter sponge.Put a new dust-proof filter sponge into the filter screen.
Next, unscrew the cover plate of the light source part at the bottom of the Sony EX130 fuselage, and lift the light bulb assembly out.
When removing the bulb from the module, be careful not to touch the lens part on the module.
Of course, the power connector of the fragile bulb needs to be carefully opened and removed.
Comparing the new and old bulbs, we can clearly see the difference between the two. The first is the two filaments. The old bulb's filament obviously has a dark oxide film on the surface due to the high temperature, while the new bulb's filament is bright metal luster.
Install the new bulb on the bulb assembly according to the disassembly steps, and the replacement of the bulb has now been completed.
The rest is to clean up the dust inside the fuselage. The Sony EX130 fuselage adopts a barrel-shaped design, and the sides are more difficult to disassemble. We start to disassemble the fuselage shell from the top of the front of the fuselage.
After disassembling the top casing, first disassemble the side dial part casing, and then disassemble it along the rear end of the fuselage, then the top casing of the product can be completely removed in a relatively simple manner.
A surprising scene appeared. After opening the casing, we can clearly see that there is little dust on the main circuit board inside the fuselage. We only use a brush to gently sweep away the dust.
The less dust accumulation on the motherboard is mainly due to the excellent design of the Sony EX130's cooling air duct, which makes the motherboard very tightly protected, which also saves us a lot of cleaning time.
After wiping the inside and outside of the body shell, reinstall the Sony EX130 in the order of disassembly.
It stands up!
The most tense lighting link has arrived. After checking the power and data cables, press the power button on the top of the fuselage. After waiting for ten seconds, this Sony EX130 that has been working for ten years is re-lit by us. .
Through observation, we can see that the brightness of the Sony EX130 after replacing the bulb has been significantly improved.
Through the noise test, it can be seen that the noise on the side and the front of the Sony EX130 has been significantly reduced, and the front noise has dropped from 68.6dB to 56.7dB, which is very obvious.
Tribute to the ten-year veteran!
Through the replacement of the bulb and dust-proof components of the Sony EX130, we can see that even a projector product that has been working for ten years can continue to shine and heat the company after replacing important components.
On the other hand, we have also seen the solid materials and design of this product ten years ago, so that this product does not affect the daily use of the company due to the quality of the product components.
but! We still regard this refurbished Sony EX130 as the company's backup projection. After all, its function, interface, and resolution can no longer meet the needs of modern conference projection.
