Westinghouse Notebook power supply

I have a westinghouse notebook. I have had it for about 1 year. I keeps shutting off. Even if I have the electrical chord plugged in all the time. The longest it stays on is 15 minutes. The power light keeps flipping from grren to orange. Is my power supply dying and where would I get it serviced?

    Laptop runs fine for 12 - 15 minutes, then shuts off. I loaded Speedfan to monitor temperatures, thinking a thermal shutdown was causing the problem, but the Core and HD are running within parameters. Another possibility was an old graphics driver, but it is up to date. I took the back off and cleaned out the heat sink and fan area, but that didn't help. The only thing left seems to be the power supply, and I have no way of checking it without the help of a pro. Since it's a cheap laptop, I doubt I will invest more than about $50 in it. I'd rather find a good 2 year old IBM Thinkpad for $250. I'll let you know if I find the issue.

If it is under a year old it should be covered by warranty,so contact the seller or manufacturer,

It sounds very much like a power pack is on its way out, and they are a sealed unit ,

try it in another power point. if power point is working fine, but you still have the problem,

and its over the warranty period.

take it to your local computer store and have them test it for you ,they will also be able to order one in and sell you a new one ,if it is the problem.

good luck with that

I have a Westinghouse Sk-26h240s TV and it doesn't start, that was before a shut down of electricity of the house, how can we fix it? It has 4 years with us

I see so many here with no sound/nopicture issues:


1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.4_23_2012_6_21_35_pm.jpg

My westinghouse 19H210S quit working 1 year 3

I also just changed the bulging capacitor and also it still does not work. Even though it was bulged when I tested it after changing it the capacitor tested normal. Not much help but clearly the 2200 capacitor is not the only problem.

Westinghouse ltv 32w The power shuts off by

I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

Westinghouse ltv32w6hd power supply

One of two symptoms on this model (LTV-32W6HD) Blue light comes on but cannot shut off. No picture; OR No picture but sound is OK. 1: In both cases replace ALL the electrolytic capacitors onthe output side of the power supply. This should get the power switch to worknormally. 2: Replace the small tiny wee little tiny small 2.0A fuse onthe inverter board labeled F1. This is the small black fuse, not the slightly bigger whiteones labeled F2 and F3.Ta Da...all fixed.

Keyboard heats up to touch. shuts down frequently. I take out and reinsert battery

This overheating problem is due to the bad connection with the power supply. Check the jack on the machine to see if it's cracked, broken, or loose. If it is, then you need to have it fixed imediately. A broken or loose jack can cause an electrical arch and do severe damage to the machine. If the jack is good check the supply. if the supply is worn out, loose, and not making a good connection it can do damage as well.
