Well, to what I know as my father told that there are secrets to those timing belt... He said "not too tight and not too loose" timing differs on every car... It's the secret of mechanics.

Have it placed by a mechanic and ask questions until you get the secret, keep watching what he does too, so you can fix it the next time you will replace it again.

Good luck... Happy Fixya ...

I have no image but sound had a tech to come look at it and said it was the main power supply board but i cant seem to find it any answer how to fix it r replace with another one......


There's a good chance you have failing electrolytic capacitors either in the power section or the inverter section or both.
Any caps in these sections that look bulged at the top, or bulged/leaking at the bottom (look for discoloration of the circuit board around the base of the capacitor) need to be replaced.
If you repeatedly turn it off and on, eventually it'll probably stay on, but every time you turn it off, the unit will get harder and harder to start up until one day it just won't.
Sometimes you have to do the opposite to start it up and unplug it for some time and then try again.

If you aren't tech savvy, don't worry, read the rest of this solution and watch the videos.

If you are handy with a soldering iron and can identify the power supply and/or inverter / FM section for the backlights, an inexpensive handful of capacitors will likely fix you right up.
Match the capacitance on the capacitors. Go over voltage if you can, and still have them fit.
IE - it's not a bad idea to replace a 10V cap with a 16V or 25V or even a 50V, but don't replace a 680uF cap with a 500uF or a 1000uF (unless you are SURE it's only doing supply output ripple filtering,
and even then, you should go OVER, not under the uF rating).

Most of the caps that go are 10V 1000uF or 3300uF.

I found some great videos of the procedure (for many Samsungs with the same issue) on youtube.

As you can see, this issue spans plasma TVs, as well as large and small LCD TVs and monitors, amplifiers, computer power supplies and motherboards, and other electronic equipment.
The parts are cheap, and skill required is minimal.
A great parts source is Digi-Key, and you can order the parts online at www.digikey.com
They typically cost under a dollar a piece plus a flat shipping rate.
The parts usually arrive one business day later.
If you watch the third video, you will see that even someone with no soldering experience can perform these repairs as demonstrated by the woman in the video.

Power button won't start


It is possible that your power supply unit went out and will need to be replaced. Also the power button itself may have gone bad as well. It is either one or the other. Power Supply Units are located inside the box of your computer

It may be a good idea to take this in to a local shop to have this done if you have never done this before. Power button switches look like this.

Depending on your computer the power supply unit and power switch may be different as well. If you know what you are doing you can replace these pretty easily the degree of difficulty is about a 3 on a scale of 10 so not that hard all you have to do is plug in everything that came out and remember where the wires go. Mark them so that you will not forget I use a b c d on and on for each part or wire.
You can obtain a new power supply unit pretty cheap. Just take the old with you when you go to buy one. If you go online to buy one just make sure that you have the same one match the case numbers and you should be fine. Most power supply units are ATX it will tell you on the old one. I would start there and change this out. Thanks for using FixYa! please vote for me. John

Dell Dimension 8300 power light flashes amber. Watched a move on it last night from an external hard drive, after which i shut down the computer eg start, turn off comp, turn off. It carried on installing...


Hi damos_turbo,

I wish I better news for you, but your going to be going into PC hell. What the amber light is telling you is that something on inside the case is bad. It could be the CPU, or the motherboard, or the PSU.
I would give you my normal advice with dealing with MO's but with the Dell 8300, it has a life of it's own.

Determining was is broken is like detective work. What I do, is take everything off the board to start. Then add the minimum to start a board to see if it will start. That's one drive (cd or otherwise) the CPU, and one bank of memory. (that's not a required eliminate, but it helps avoid beep codes) Also, if your going to load a ide drive, make sure you set your pin setting correctly on it. Now, you should get the power supply on, and the cpu. If those don't power up, it's then either one of the five elements. The CPU, Power supply, Ram, Drive, or the motherboard. The next step is to replace each one of the first four to see if you get any change. If no change, then I usually get another board that I can test the first four, and make sure that they work. After that, then I say you have a dead Board. As I said in the beginning, PC hell is here.

I sometimes just advise people to get a new computer, If you like dell's they have new ones for $300.00 to not only match what you have, but will have a whole lot more speed.

Good Luck and don't forget to leave a rating.
Thanks
Mark

I have customers overseas that have the EMACS HP2-6460P power supplies in their systems and they say that the systems do not shut down properly and they eventually unplug the power from the wall. What...


Hello,

I would ask the customer a few questions:

1. Do you have the computer connected to a power adaptor or is it a voltage switching pc?

2. Has the pc always done this? If not, have you changed any power setting in the control panel? (Or have the checked the power setting.)

3. When was the last time the pc shut down properly? Maybe the pc is trying to install updates and need time to finish the install. (If when powering off the pc you see a shield over the power icon from the start menu, let the pc run its course and it should power on/off correctly.)

Good Luck

One of my computers says that my "System Battery is dead" and I don't know what to do


system batery refers to a watch bater on the mother board used to keep time
it is as easy to eplace as a watch batery

Instructions Difficulty: Challenging Things You’ll Need:
  • Replacement Battery
  • Electronic Or Printed Backup Copy Of CMOS Settings
  • Backup Utility
  • Grounding Wrist Strap
  • Phillips Screwdriver
Restore the CMOS settings Step1If you've never made a backup copy of your CMOS settings (by using a backup utility program such as Norton Utilities or by printing a hardcopy out on paper), look them up in the printed documentation for your system or call the vendor of your PC. Restoring your CMOS settings from a backup will help determine whether the battery is the problem. Step2If you're using a backup utility to restore the CMOS settings, insert the emergency startup disk and follow the prompts. Step3Use the Setup utility that's built into your PC's BIOS to re-enter your CMOS settings manually. Restart your computer and wait for a screen that tells you what key or key combination to press for Setup. Step4If re-entering or restoring your CMOS settings solves your problem, then it's possible your battery is fine and the settings were corrupted by a virus or some other anomaly. If, however, your PC "forgets" the CMOS settings you just re-entered or restored after you turn the machine off (and then back on), you probably have a bad battery. Locate the dead battery Step1Turn off your PC. Step2Before opening your PC case, put on a grounding wrist strap to prevent discharging static electricity onto any sensitive components. In fact, throughout this procedure it's a good idea to frequently touch something metal (other than your PC) that's resting on the ground, to make sure you discharge any static electricity. Step3Open the PC. For most PCs, this entails removing a few screws with a Phillips screwdriver and sliding the case off. Step4Locate the battery on your PC's motherboard. This is trickier than it sounds because PC manufacturers have used many different types of batteries for CMOS settings. The most common are lithium, like the kind in watches, but they could also be a pair of AA batteries. Or they could look like two cylinders encased in red plastic: a silver box or a red and black box. Step5Draw a picture of the battery, showing its exact position on the motherboard. Remove and replace the battery Step1Examine the battery carefully to see how it's attached to the motherboard. Most likely, the battery is attached by a clip or with Velcro. Some older PCs might have the battery soldered to the motherboard. Unless you're confident with a soldering iron, don't attempt to replace one of these. Step2After you've removed the battery, take it to an electronics store to match it with a replacement. Step3Replace the new battery in exactly the same position as the old one, referring to your drawing (see Warning). Step4Restart your PC and re-enter or restore the CMOS settings.
