Question about Westinghouse SK-26H240S Television

1 Answer

I have a Westinghouse SK-26H240S LCD TV. It is about 3 years old. I never had a problem with it until a few days ago. It turns on but I get no picture or sound. The screen sometimes has some horizontal lines on it and sometimes is just white. I can not even get it to show the channel or input it is set on.

This is definitely a problem with the LCD controller of the tv or the LCD panel itself. However if I were you I would hope that its just the controller(which costs about 50$) and go ahead with the replacement to see if that resolves the problem

Westinghouse 32 inch tv just turns off after 2 or 3 days of use


Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

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:

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

Westinghouse SK26H240S - Sound works but no picture?


There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

White Westinghouse flat screenTV freezes up and hums.


Sometimes if you just press on your overscan button on the remote and make the picture a little bigger or smaller the humming noise and freezing of the picture will actually stop.
