Question about Olevia LT42HVi 42 in. LCD Television

4 Answers

OLEVIA 540-B11 42" LCD-Inverter supposedly shot craps

Talked to Olevia tech support-this was their guess as to what happened. Have audio but no picture. The TV is slighty over 2 years old, and in my mind this thing should not ave shot craps already. They say inverter itself cannot be replaced, but I find that hard to believe. I have removed the back panel off tv, and see all kinds of circuit boards, etc. I have no diagram so I am not sure where the inverter would be located.

Any ideas if inverter itself can be replaced; and/or get a diagram or manual showing where this board is located?

thanks,
Todd

    Robert:

    Will try to get the sheet metal portion off soon. I will try to email or respond to you if I can get to the part-may take some time as I will be out of town for a bit-so it may be a week or so before I can attempt-will let you know for sure if and when I can get to it-I do appreciate the advice-Great idea Robert!-Appreciate it since I am in no way a techie type person.

    We have sound, but no picture. We can see faint image on screen if looking at it just right. Do you know where to get a backlight for an Olevia Model 540-b11? Ours is a 40" LCD.

    Hi. I have the same problem w/ the same TV. I tried the "shine the light on the screen" test, as Robert suggested. I saw the "ghost image", so does that definitely mean this is a backlight issue? Does anyone know what part I would have to buy, and tips on installation? Or should I just shop for another set? Thanks in advance! - Lynsie

    We were watching TV this evening & our picture just went out. We do have the "ghost" image, but I have no clue about what to do with this. We bought our TV from one of those home shopping channels about 2 years ago. Did any of your come from there too? Maybe it was a bad batch??? Let me know what you guys came up with to fix it.

    I have the same problem with the same TV which I bought from a home shopping network about 2 and a half years ago. I get sound, but no video. I haven't tried the flashlight trick yet, but from the many forums I've visited that have described this identical, I have no doubt that it's the same problem.... I'm ready to make the first incision... Nurse? 3 mm phillips, please :)

    Hi, I got a lg47SL9500 and from one to the other day the screen looks like on the picture. Maybe someone got an idea what is the fault. I already screw it open and take a look on the elkos but they looks good. The only thing that wonders me is one red diode on the inverter board, i also take a picture but i think i only can upload one. I hope my english is not so bad, I am from germany.thanks for the help.

HI TODD , I HAVE THE SAME PROBLEM WITH ONE IN THE SHOP IN VA I AM WORKING ON NOW. THE BACKLIGHT IS PROBALLY BAD ON YOURS ALSO WHICH IS THE BOARD ABOVE THE MAIN BOARD. IT IS LOCATED TOP CENTER LOOKING AT THE BACK. IF YOU GET TO IT SEND ME AN EMAIL WITH THE P/N # , I WILL DO SOME RESEARCH. OLEVIA DOES NOT HAVE THE BOARD AND NO HELP ON FINDING IT . THE MAIN BD IS A POSSIBLE PROBLEM BUT TO INVEST $400 IS JUST TO COSTLY TO TRY.OLEVIA DOES NOT HAVE ANY DIAGRAMS TO USE THE CHECK TEST POINTS OR COMPONETS. TO CHECK FOR NO BACKLGHT SHINE A VERY BRIGHT FLASH LIGHT ON THE SCREEN FROM THE SIDE AT ABT 30 DEG AND LOOK AT THE SCREEN ABT 45 DEG > THE SET ON AND ON A CHANNEL. STUDY AND YOU WILL SEE A GHOST IMAGE TO CONFIRM NO BACK LIGHT.KEEP IN TOUCH MY WE CAN HELP EACH OTHER.

    HI AGAIN TODD, FORGET WHAT I SAID ABT THE BOARD LOCATION GOT TO MANY SETS OPEN. THE BOARD SHOULD BE UNDERNEATH THE SHEET METAL THAT ALL THE MAJOR PCB's ARE MOUNTED ON. YOU SHOULD BE ABLE TO UNPLUD BOARD CABELING AND DISSASEMBLE TO GET TO A BOARD THAT HAS TRANSFORMERS MAINLY AND ABT 4X6 IN . IN SIZE. YOU WILL NEED TO CONFIRM IT HAS A SUPPLY VOLTAGE THEN EYEBALL FOR POOR CONNECTIONS. I TALKED WITH A TECH AT LCDPARTS.COM WHO WAS VERY HELPFUL AND SAID BY PART # ( ONCE WE KNOW IT) HE MADE BE ABLE TO SUPPLY OR SUB.

SOURCE: OLEVIA 540-B11 42" LCD-Inverter supposedly shot craps

Ok I'm Not an expert on Olevia's but I've done enough LCD Tv's to know a few things. The inverter boards are usually located on the right and left side edges at the back of the chassis. They usually run from the top to the bottom and have multiple connectors coming out to feed the backlights in the LCD panel. I can believe Olevia might not supply them (most other companies do) except as a part of the LCD panel. In some cases, the manufacturer of the LCD panel (Olevia does not make their own panels) does not supply the boards separately to the company making the set..In terms of getting a diagram, the panel maker (probably chinese or korean) probably has one, but Olevia may not. Your best bet would be to keep an eye on a site like this one:
http://www.shopjimmy.com/
They get scrapped TV's and remove the inidividual boards for resale. I have already checked and they don't have the board you're looking for right now, but that can change. Sorry I can't be of more help!

Our olevia tv is going black, has no picture, but does have sound. It keeps going black off and on. What is happening? Thanks.


The backlight inverter board can be bad or the power supply for the inverter board is bad. Check the power supply first since it is easier to get to than the inverter board.

Power supply is shot ..need a new one and the repair place said they can't order one. Olevia Model LT30HV


Does it have a lot of bad capacitors (bulging top)? Do you have the picture of the power supply? Two most common parts that go bad in the LCD TV are the power supply and the Backlight Inverter board.

If an LCD TV has sound but no picture do the following:

Use the source button to ensure that source is not set to the wrong input.

Try unplugging power cord for ten minutes, to ensure it is not a setting problem.

Check all the video cables at the back of TV.

Check Light /Color settings.

If problem persist and does not depend on external receiver or settings, then it is likely an internal fault.

If it has sound but no picture then one of the following parts is faulty, and must be tested and replaced:

The inverter is the high voltage board that provides variable power to the backlight lamp. This is the most common. When inverter is faulty you can get no picture, or a very dim picture that can only be seen by pointing a torch light with a 45 degree angle on the LCD surface from very near distance.
The inverter must be tested by reading voltages with a multimeter.

The LCD ribbon cable/LCD display and connectors.
This is quite uncommon, but happens. If the TV had been hit or moved the LCD cable may have slipped out, or the LCD connector may be damaged.

The LCD controller board.
This is the board that controls the video signal, it is difficult to test, as there is need to read determined values on IC pins. To test this board you need to purchase a service manual and follow the troubleshooting diagrams on service manual.

Input/Output Signal boards.
This are the boards where you connect the video and audio cables, if a signal board is defective, then you may get no picture on particular inputs located on faulty board.

If under warranty contact the manufacturer ringing the number on the user manual.

If you want to repair at your own expenses, just locate any good qualified repairer.
