The TV will not power on with remote or manual button
I purchased 2 years ago a 15 inch LCD from Target and it worked fine but now the AC/DC power supply cord has this annoying popping noise and it will not power on. I have unplugged every plug possible and sometimes it will power on after the annoying popping noise from the supply cord. Is it possible that the plug is faulty or is it time for a new TV? Thanks so much for your prompt attention to this matter.

Download the user manual to your TV. Clik here to download it. See whether audio options to it are set right. If all are right, check its speaker. If speaker is OK, the audio output circuit section should be troubleshooted. If you feel any difficulty in downloading the manual, send your email address to me. I'll send a copy of it to you by return mail.
You should buy a sodering kit and remove the buldging capacitors yourself. Find a local electronics store, I used Radioshack, and see if they can match the capacitors. I had this happen with my Samsung lcd about a year ago and just help another friend with the same issue yesterday. The sodering is not as hard as you'd think.
The capacitors should be under $5 v. paying a few hundred for the power board.
Found universal replacement remote for Viewsonic N2750 at Target for $15. Works perfectly. it's the Sony RM-V310A.
Tried all 5 remotes from Walmart, none worked even though it said would work on back of packaging..Target has about 5 Remotes only this one worked.
My original remote died after 2 years. ordered an original replacement. that one died after 2 years. They're ****.Manufacturer discontinued it. found one online for $50.
Just get the Sony RM-V310A at target.
Try leaving the TV unplugged for 30 minutes so theTV can reset itself.
If that doesn't work, most likely the TV has a power supply board is the problem. Or, it's just a fuse that blown inside the TV.
But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20. And most cases the new part cost less than $15.

Picture is not centered on monitor leaving a 2 1/2 inch; black border on Philips LCD By dmorrow54 on Nov 13, 2007 Again, nothing in manual for Philips LCD will correct the fact that the picture in HD-D mode will not center. The picture runs off the monitor on the left (facing the monitor) with a 2 1/2" black border on the right (facing the monitor). Using the format button on the remote of directional arrows will not correct the issue. The wide-screen/ full-screen function with format does nothing. Moving into TV mode, the format function works to display screen in several ways 4:3, 19:2, super-zoom, wide-screen, full-screen. Help, please. posted 3 years ago
I have a Philips 30 inch LCD and solved the problem by using the circular arrow button on the TV remote. Pointing it at the TV and clicking "right" (3 o'clock on the button), the picture moved right. Same thing on for "left". Worked for me. Add a comment

WOW! It works!! The picture on my Magnavox (aka Philips) 37MF321D had shifted to the right. I figured I had a big repair bill coming up soon. But hey! Just used the TV remote as described by "Guest', and re-centered the picture to the left. Wallah! Thanks ""Guest" whomever you are! Reply
It could be the AC adapter. That is easy enough to check with a DMM. Turn on the meter, set to volts dc, push red probe into the hole in the output power jack and touch the black probe to the outside of the same jack. Have someone plug the AC cord into a good outlet(one you know has power). If the adapter is working you should see 12 vdc displayed on the meter. There still could be a problem as I recently found an adapter which displayed the correct voltage with no load but little or no voltage with a load. Testing with a load is a problem if you are not familiar with the procedure. Odds are if you have 12 vdc the adapter is fine and you have a short somewhere in the monitor. If you are handy with tools and feel confident, remove the back of the unit and check the fuses in the power supply. If they check OK you probably can't do much more. Unless you are an electronic tech you will need to take the unit to a shop for repair by a qualified tech. Good luck.
