    You can also get a new power circuit board from Encompass parts. I found they had one for $91 + shipping.

First, this is not a projection TV.

Faulty parts on PS board , bad press for Samsung

Because the Samsung LNS4051D would not turn on and the power LED would blink 4 times and the relay would click and this would repeat again and again. I replaced power supply board parts CM806, 811, 812 & 817, all 1000 uf 10v capacitors, three had their tops bulged up slightly that I missed on initial visual inspection. After seeing the reports of problems with these caps on http://www.fixya.com/support/t1336881-will_not_turn_or_off , I replaced them with Radio Shack part 272-1032, 1000 uf, 35v. They are slightly bigger, but fit OK. TV is working fine now. Cost was 4 x $1.59 = $6.36 plus the time. I saved between $100 to 300 in the process of either replacing the board or getting the unit serviced. If you are not comfortable replacing components which means using a soldering iron, you can replace the power circuit board, available from discount-merchant.com.

1992 mazda protege dx 4 dr won't start. Battery is only 2 months old. Makes a fast ticking sound from inside car similar to turn signal light out.


Hi Robin, As the battery is new and presumably not defective, I think you should suspect the soloniod fitted to the starter motor. If that component has become defective it will give the sound you're reporting. Depending on where you live in the world and the labour charges, you can have the contacter's replaced or the starter motor (if labour charges are high) Regards John

Why is my samsung clp making a clicking noise?


Is the printer making a clicking sound when it is printing? Or is it just making a clicking sound but there are no light and the printer appears to be dead except making a clicking sound?

I know of a cause for either case.

Case 1. It is clicking when printing. Sometimes the toner cartridges are not seated properly in the imaging unit, and causes the gear on the cartridge to slip making a clicking sound as the gear is being turned. Try pulling out the cartridges and try turning the gear. It should turn smoothly without binding. If it binds, there is not much you can do about it except replace it when it goes empty. Reinsert the cartridge and check that it inserted completely into the imaging unit.

Case 2. Printer is dead, not printing except making a clicking sound. This is due to the power supply board failure. Usually the failure is due to a blown filter capacitor on the power supply board. The power supply is located on the right side of the printer. Remove the right side panel to get access to the board. The board can be either repaired or replaced. Hope this helps you.

Hi,. I own Asus Xonar DX two years ago without problems... I formatted my PC (Win7 x64) yesterday, and now i have sound issues when i use 5.1 feature... The sound turns slow and distorted... I uninstalled...


if your computer came with a motherboard disc the sound drivers could be on it
you might have to uninstall then restart your computer then reinstall both the sound drivers and the sound card make sure you have both of these devices backed up to a disc before uninstalling
a yellow? question mark means you need to install/update driver to do this
right click to install driver also
click start control panel administrive tools computer management device manager scroll to sound,video and game controllers you might see a yellow question mark? Right click to reinstall drivers
click start control panel sounds and audio,volume,advanced,speakers select appropriate speakers also audio you will find 3 drop down lists make sure you have the correct settings there
also
click start control panel sounds and audio devices you can adjust the volume there also select speaker volume you can change your settings there you can also tick in the box place icon in taskbar
if his does not fix the problem

have you tried this control panel sounds and audio,volume,advanced,speakers select the appropriate speakers from the drop down list or navigate to the device manager scroll to system devices + to expand,system speaker right click properties then select use this device (enable) also you might check
the speakers plug/outlet is usually at the back of the computer you will have to open up the computer to check the lead attached to the rear of the input plug make sure the connection is good
try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the sound card and the CPU central processing unit dust causes static to build up in a computer
hope this helps

My Samsung LNS4051 has sound but no picture. I replaced 2 bulging capacitors (CM807 and 808), and it worked for less than 1 day. The other 4 caps frequently mentioned on this site appear to be good, but...


When you replace obviously bad capacitors (bulging, leaking), make sure you also replace any adjacent similar capacitors even if they look ok because they are almost certainly bad too.

If you find 2 bulging ones in a group of 6, don't skimp, just replace all 6 while you have it open.

Good luck and please post back with how you make out.
