Tv dead. bad power supply for 17lcd tv model ch hgl 1710 ps 12v 130 watts

Hello Anvar, hi, to run the power supply on its own, you need to short the green wire with the black wire. (plug in the unit)
using a Volt meter, select a range of DC 50V. put the black probe of the voltmeter to any black wire, and the red probe to the ff:

red is 5V
Yellow is 12V
orange is around 3.3V
Blue is negative 12 (switch or interchange the probe to properly read 12V on the voltmeter)
White is negative 5.

Check that the power supply fan is operating. If not, take it back under warranty.

No, it indicates a bad power supply.

1) ALL the lights use less than 1 Watt
2) EACH fan uses 2 to 3 Watts

3) A typical processor uses 55 to 125 WATTS.

The base model of the HP Pavilion a1620n Desktop PC, comes with an Intel Pentium D 925
(Operates at a maximum of 3.0GHz)

The Intel Pentium D 925 uses 95 Watts,

In most cases the inside of the computer is dirty, as well as the inside of the Power Supply, and it's fan.

Heat = Wasted Energy
When the Heatsinks inside a power supply, and it's Fan, (To include the fan blades, fan center hub, and surrounding fan cage), become clogged with gunk, the cooling capacity of the power supply drops tremendously.

Since Heat = Wasted Energy the power supply tries to keep up with the power load demands.
Eventually components inside the power supply fail.

(Usually the Electrolytic Capacitors are the first to go)

The power supply inside a Pavilion a1620n is a common SMPS. Switched Mode Power Supply.

The style is the common ATX, that is used in over 90 percent of desktop computers. (ATX 12V)

The Wattage is 300 Watts.

Should you like help in finding a replacement power supply that is affordable, and reliable, just state so in an additional comment.

I do advise staying away from the cheap generic models, as they can fail in 6 days to 6 months. ($20 to $25 range)

Any power supply will do as long as it has the same specs as the dead one, which will be:

Input : x Volts AC
Output: x Volts AC or DC
Watts: x
Amps: in millamps
Polarity: (for power supply with DC output only) Center pin = plus or Center pin = minus

You should be able to find the matching transformer/adapter/power supply at Radio Shack.

More info, let me know.

P.S. The power supply you received may be the correct one -- check to see if the specs match the old one.

Best place on the planet / if they don't have it they can also repair for a flat fee of $23.00

see this article http://web2.murraystate.edu/andy.batts/ps/powersupply.htm

It looks like a standard size case. Any power supply should fit. I doubt you'll find anything under 400 watts nowadays.

Heres a place with great prices on power supplies.. the prices jump around, so browse slowly:

yes PWR SPLY must be connected to MB and MB must be grounded when bench testing. thats the quickest easiest way to check..
