Westinghouse SK-32H240S Television - Answered Questions & Fixed issues


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.

Is it under warranty? Have you tried to contact Westinghouse? Or the place you bought it? Did you register the TV? Those are all places to ask.

b7d051c6-2386-46f1-9de1-bf708dde078e.jpgThis is often caused by failing or failed capacitors in the power supply unit (PSU). In my case I had a Lexsor 32 inch LCD flat screen (psu part number KAS200-5S241812XS VER A2.1) but these notes probably also apply to any number of similar LCD flat screen TVs with similar problems. Make sure and double check the values of any components you replace against your own TV's. The component values I have given are just for my make and model of TV.

Naturally these instructions should only be used by fully competent persons who know what they are doing and anything you do is entirely at your own risk. If you do not feel competent to look inside your TV and do the repairs yourself then maybe consider printing these notes and giving them together with your TV to a fully qualified and certified TV repair specialist.

Here's what happened to my TV and how I fixed it:

The blue front light came on when my TV was turned on but there was no display or sound. Sometimes repeatedly pressing the on/off button many times finally got the TV to turn on but it made a buzzing / hissing / static crackly noise and it took many minutes until the LCD display and sound came to life. Eventually even repeatedly pressing the on/off button failed to work and only the blue light on the front panel came on with no other activity.

CAUTION: MAKE SURE YOUR TV IS UNPLUGGED FROM THE MAINS AND *NOTE* THERE ARE VERY HIGH VOLTAGES THAT MAY STILL BE PRESENT INSIDE THE TV EVEN AFTER IT IS SWITCHED OFF AND UNPLUGGED FROM THE MINS POWER SOCKET. TAKE VERY GREAT CARE NOT TO RECEIVE AN ELECTRIC SHOCK. MAKE SURE YOU REALLY KNOW WHAT YOU ARE DOING *BEFORE YOU DO ANYTHING*!
I opened the TV and located the PSU board (see photo). Six of the electrolytic capacitors were clearly puffed at the top (your TV may have a different number of capacitors that need replacing). They should all have flat tops so if they look "puffed up" (a bit like a bottle of fizzy pop that's been shaken) then they need replacing.
Please note that in my PSU three of the capacitors were orange 25v 680uF electrolytic radials and three were black 35v 680uF electrolytic radials. I un-soldered the capacitors from the board and replaced them all with 35v black 680 uF electrolytic capacitors (I reckon the few extra pence the 35v ones cost instead of the 25v ones is money well spent!)

Re-assemble the whole thing and - there you go - I hope you are as lucky as me and your TV is as good (or better) than new!

Happy viewing!

yes, it has pip. Use the menu to select the pip setting.

It seems that your unit has some sort of Video side, PSU fault, or a problem to the Video section that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur.
You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.

Its not on or you cannot see it?

Possibly it is just the input that has been changed. Find the input and press that a few times to cycle through. If that does not work I will check back and ask some other questions to get this resolved.

problem in the vertical section, check for burnt vertical ic or bad capacitor near the ic.

Switch off TV, switch off power, remove plug and wait for 48 hours and retry.
If problem persists, I suggest it is better to refer it to a qualified service
technician, since the back cover has to be opened for investigation/rectification.

the board will be hard to locate but run between 80- 150 if you can find them. However your symptom is most likley cause by one of the Transformers. Which you can get replacement transformers from www.tvrepairworld.com send them a email from their website by hitting the contact button on the right side.

The voltage source to back light inverteres are from the main power supply regulator board. Check it.

Either the lens on the front of the set for the remote receiver is dirty etc or the infrared receiver in the set is bad.

The having to get very close and the fact more than one remote reacts this way means the trouble is the receiver is bad.

I have seen this a few HUNDRED times in my career.
