Neighbors power supply went out I put in a new one that I already had and when I try and power up all it does give me the blinking light. Is the mother board may be screwed up also? Any chance of resetting the mother board some how?

    Thanks for the quick responce.I actually had an older atx motherboard that I had down in the basement for 3 years and I pulled it out and hooked it up. and everything came up just like it should. Good thing I still had the old mobo.The neighbor decided to get a new computer already anyway,but I get the old one. It is a decent set up so I thought I would get a new mother board to put in. How about a suggestion on a new mobo.Don't know enough about them but I can put one in and take them out. Don't know anything about clock speed that a lot of you guys talk about. I guess it speeds up your computer but you can also overclock, which is not a good thing. Is that right.

Were the power supplies compatible (ATX etc)? If they are try pulling out the ram and see if you generate any beep codes. If your pc bots add them back one at a time. And yes I have seen power supplies wipe out processors and or motherboards.

Panasonic Viera. The TV went off & I got 4 blinking red lights. Installed new power supply. I plugged it in & it made 2 clicks but still will not turn on. I'm still getting 4 blinking lights.Any ideas


Great set - you were on the right track but ........
U will have to do what I did on these new sets. Google has dynamite blogs on the workings of these sets, what each board does, and what are the symptoms of a problematic board. Knowing exactly what your tv is doing and not doing you can use these guides as a wonderful way of finding out what other boards could be at fault besides just your power supply. U have nothing to lose and all to gain with the free info. Good luck.

No panel lights, no fan, flashing front left light


the blinking lights means power issue. If you already plugged the computers power cable directly to the wall and stll get the blinking power light then your probably looking at a bad power supply in the computer.
Just for measures go into the system and if you have a video card remove it and start the system up. Also take out the memory stick and put them back in just incase during the move some components got loose. Put on your detective hat and check all connects. if problem still persist replace the power supply. In Computers terms thats called the PSU (power supply unit)

I turned on my Dell Dimension 4700 computer,but the amber light started to blink . I held the start up button for 5 seconds and the light went out. I tried to start it up again and got the same thing,...


Vaughn it sounds like the power supply is going bad, try another known good working power supply. If that doesn't work then the motherboard would need to be replaced. If the power supply isn't giving the correct voltages that could cause the computer not to turn on. If the motheboard isn't able to convert the voltages properly then the motherboard could be faulty.

Turned it on a minute later went black


Good day sir/ma'am hi, if you monitor turns black, here are the more common probable reasons;
  1. Your PC went to standby the screen saver kicks in, just reset your PC then the monitor will power on again.
  2. If not, your PC is not giving you video signal, check to see if another monitor will work, we then know what part is bad, the monitor or the PC.
  3. If the monitor is the culprit, then your monitor's back light or inverter board just went bad. you need to replace it.
There are usually two main circuit board on your monitor, the power supply board and the main board, at this point, you need a professional to do the work.
The process is opening the monitor and locate the LCD screen connection to the main board, to check if the contact is snug. we then test. if still nothing happens, Then we go to the power supply board, to check for connection problem, It would help if there are light signs, like blinking, orange, red, green and the likes? Anyway, if the power supply board is not the faulty one, we substitute the main board with a good one and test to see if it will work, test again. If still no respond, we test a new LCD unit, then test, at this point the monitor is working already, if not, we then replace the power supply board. Huh, very expensive, we already have a new monitor. Reminders, these are to be done by a trained personnel. If you attempt to service this, its expensive, so I suggest you let the service shop do this for you to replace only the faulty part.

TV picture went out. stand by/timer light blinks when I turn on the TV. no other response from TV.


The timer light blinks representing the fault on the tv. If the tv blinks in an orderly fashion then the number of blinks before pausing is used to indicate the fault. This can only be determined by looking at the service manual for that set. If the blinking is continuous without pauses after a number of blinks, then it indicates there is a problem and the first place to look would be in the power supply. Either the power supply isnt supplying power to the Line output transformer i.e an open circuit or short circuit..OR the line output circuit has a short. Without a diagram i cannot guide you which components to check..but..swollen topped capacitors in the power supply are a give away :)

No Picture - Lamp Indicator Blinking


This may be the main power supply, or the lamp supply. This is providing that the new lamp is okay.

The service tech will swap out the modules to service the set.
