Won't turn on - 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!

SOURCE: My Westinghouse won't turn on, please help!

I had the same problem...turned out it wasnt the TV at all. It was actually the wall socket. Seems I had to many things plugged into one wall supply. (i.e. xbox 360, wii, audio reciever, dvd player, vcr, etc...) after switching some other items to a different socket my TV works GREAT!! I hope your problem is this simple!

SOURCE: No power on Westinghouse LTV-46w1 Television

This kind of failure is very common; that is why I suggest that one should keep the old CRT TV, buy a converter and put them both in the garage or basement so they are handy when our s*e*x*y new sets go belly up.
With fair confidence I can say that the main power supply has failed.
If you want to try this on your own, it only will require the removal of a few screws and a flashlight.
- Unplug the set overnight. - Remove the rear housing  - Use some logic and these tips; look for a separate board with larger than average parts on it and seems closer to the power cord than others. This will be the power supply.
Check the board over for something that looks like a part number and record it. If you find more than one, one of them will be the bare board number, the second (sometimes on a sticker instead of printed directly on the board) should be the part number for the assembly.
Search for the Westinghouse service company nearest you and call them with this info. Ask if they repair these or just sell new ones. If it is the latter, don't pitch the old one, continue to look for a repair service that will take it on after you have the new one in place and can watch your favorites again. The new supply will likely cost between $90 - $150 and with a little common sense, most anyone can remove and replace these in the set. Expect any repair to cost about the same as a new supply; US technical labor costs more than Chinese assembly labor. 
These supplies can be as reliable as the primitive older type but companies refuse to use the high-grade components necessary to give them a long life so they fail much sooner than the old, less efficient kind known as 'linear' supplies.

SOURCE: got new tv Westinghouse LTV-32W1 32 Inch

Hello,
in this case i have to know if your tuner is working fine or not. First of all i like you to connect any external player Exp. DVD or blue-ray player if that works with audio then it is inverter board. if audio doesn't work then its main board. Also you will find out that if dvd is working fine on your tv than your tv setting is wrong or the tunes is dead. either way if tuner is gone then you have to change the main board. Either way let me know what went wrong i can provide you more information about what part need and where can you get it from.
Please let me know if you have any further questions or concerns. Also rate me if you like this post.
Thanks.

This going to be tough one to figure out, but at least the back light inverter board and power supply are working, unhook it at least 1/2 hour?
You may have bad main logic board problem. Try reading my guide here and see how much the main baord may cost you.

My sony bravia klv40ex600 won't turn on,the light indicator for power,volume and channel is on, the screen is still black


Hi, have you tried pressing the TV button that is under the On/Off button on top right hand side of remote control? Some times its possible to accidently press the DVD or VCR controls and this by-passes the TV as a remote?
Another cause can be a poor or low battery in the remote itself. If you have no luck let me know & we can try some more things, however, I have heard that The On/Off Switch on the TV can be a problem. Goodluck, Jon..

Do you have back light when turning on the TV? if you do then just replace the main board should resolve the problem. if you do not have back light, you will need to replace the inverter board(s) depending on your model. The inverter board(s) is located on the left side of the TV facing back of TV. you may have two inverter boards depending on your model. the other is located on the right side of the TV. Both mount vertically.
