Big-Screen TV Related Questions

The Big Screen TV’s are developing fast with the rise of new technologies like LCD, plasma display, projections televisions and so on. These televisions are flat screened and use high definition technology. Moreover, the television industry is changing the aspect ratio to 16:9 which could conveniently be used by these televisions. Below are frequent asked questions on issues relating to Big-Screen TV that has been answered by the Experts.

How to remove the white dots on the screen of my Mitsubishi Big Screen TV?

To begin with, the DLP chip is an electronic device located inside a television set. It not only produces an image but also projects it on the front screen of a television using the projection lamp and the light engine. In this case, the reason these white dots are appearing on your screen is because the DLP chip inside your TV is failing. Therefore, to fix this problem, you would need to replace the chip. However, it is always best to have it fixed by an expert if you want to prevent your TV from any further damage. You could visit various electronic retail stores like ShopJimmy.com to get a required DLP chip. Moreover, you may want to click on http://www.tvrepairpros.com/ to find a TV repair shop in your locality for getting the chip replaced. Usually, you could expect to pay around three hundred and fifty to four hundred dollars for a repair like this.

How can I replace the lamp of my Mitsubishi Big Screen TV. It got burned out.

In this case, you would need the owner’s manual to replace the lamp. You can download the manual by clicking on http://www.mitsubishi-tv.com/support.html. Once it’s downloaded, you should go to page one hundred and twelve on the manual to get information on how to replace the lamp. You would need to remove a particular door to replace the lamp. You would find that door on the back of your TV. Now, after you have visited the website, you would have to click on the ‘Product Documents’ option to enter your TV’s model number. You must know that lamp replacement is considered a consumer replaceable item. However, before replacing the lamp, you must ensure that the TV was off for an hour. You should also avoid touching it as the oil on your skin might damage the lamp.

How can I get my Mitsubishi Big Screen TV to switch on? The green light appears but then immediately lights off. What do I do?

In this case, the first thing you could do is perform a soft reset on the TV’s internals by disconnecting the TV for thirty seconds and then connecting it back. However, if the reset procedure doesn’t fix the problem, all you would need is a technician to look at the TV and disassemble its parts. They would find the faulty capacitors and replace them. An average capacitor would cost you around one dollar each. Usually, such problems are likely to occur because of failing capacitors. A capacitor is an electronic component that looks like a battery. With time and heat, these electronic parts can go faulty and may dry up. Normally, there are cases when multiple capacitors can become defective even before the TV is dead completely. However, there is no error code in this. Therefore, it looks like the power supply cannot turn on from its standby mode because of these faulty capacitors.

How do I remove the reddish tint and blue convergence from the screen of my Phillips Big Screen TV? The blue convergence is hazy and I can’t view the night scenes properly.

Based on what you have stated, it looks like your TV has a convergence circuit failure. These problems are normally very common in these sets. In such cases, it is more than likely you would not find any reset procedure or button that you can push to cure this problem. However, if you could visit http://www.tvrepairkits.com/xcart/search.php?mode=search&page=1 you can purchase a kit that would have all the parts you need to fix this issue. Moreover, it would provide step by step instructions on how you can fix this problem by yourself. Now in case you are not very comfortable handling this issue on your own, you can contact a technician to repair the set for you. In that case, a repair like this would usually cost you around two hundred and fifty dollars for parts and labor. You would want to visit http://www.tvrepairpros.com/ to find a technician in your locality. The Big Screen TV’s have high resolutions. With many options available, they have a variety of technical specifications too. Therefore, every consumer should consider both the benefits and limitations before purchasing a Big Screen TV. If you need clarification about your specific situation with respect to issues related to Big-Screen TV, you may ask a TV Technician expert to evaluate your case details and provide a technical insight.

  • Hi, and happy Thanksgiving! I have a Philips Multisystem LCD

    Hi, and happy Thanksgiving!
    I have a Philips Multisystem LCD TV Monitor, Model 300WN5BV, 30 inch. I bought it in 2006 for about $2000 when I was moving to Switzerland. I am back in the US and it has worked well for all these years --- until recently. Now the picture goes out sometimes when I am watching TV. It can work fine for several hours and then BOOM - sound but no picture. I can go back the next day and it is fine again. This has been going on for a couple of weeks. When I go to turn the monitor off and on again, there can be a flash of picture for a second. Is this something that can be repaired relatively easily? Is it expensive and would it be worth it or should I give up and get a new TV?
  • sharp brand 42 inch tv is stuck on input 1 and it will not

    sharp brand 42 inch tv is stuck on input 1 and it will not turn off either remotely or manually and will not allow me to watch either tv or a dvd. I have tried working and fixing the problem via the remote and the section on input 1 and it will not even turn off the tv, much less allow me to do anything else. The tv was working perfectly switching back and forth between channels and dvd I was watching less than 5 minutes before it went into this state. Please assist at your convenience. Thank you
  • Hi Jeff! We have had a proview since 2005 and for the longest

    Hi Jeff! We have had a proview since 2005 and for the longest time we have barely been using it because it seems to need to warm up when turning it on. We turn on the power switch in the back, push the Power button on the top and it stays black. we leave it like that with the green light on for 5 min and turn it off and on again by the switch in the back and then press the power button again. if we are lucky and wait long enough it will come on (blue screen) if not we turn the switch on the back off and on again, and press the power button and wait. Is this fixable?
