Dragon22 -
I'm working on posting a procedure/solution somewhere where all of the photos can be posted. May wind up on Flickr to get all of the pictures loaded on there. What state is it in? If you have the power distribution box, motherboard, and CCFL inverter removed, and are staring at the back of the box.

If you have all of the screws and components, I will help you walk through it.

Its a VW32L HDTV40A how do i take the back cover off. And is there anything i should watch out for ?


screws all around the outside of the TV can be removed with Phillips screw driver, usually can leave it standing, but depending on the model, some of the stands need to be removed on the Vizio TV's.

Keep your screws organized so you know where to put them when you put it back together.

remove all the screws on the solid back piece, and it should pop right off.

Be sure to have it unplugged for quite a while before working on it, capacitors can hold charge that will give you a good shock..

My tv mitsubishi wd62628 has a sound but no picture, lamp is good, what is the problem?


How do you know the lamp is good? How did you tested it?
I will hypothesize that you either: 1) tested the lamp separately on another TV or using an external rig and when you did that the lamp went on, while when you put it back in your own TV the same lamp would not go on
or: 2) tested the lamp mounting it inside your TV and saw it lit up,
In case #1 you may be having a bad ballast since your TV powers up (you get sound) and the lamp is tested good. If the lamp does not when you put it in your TV then the problem is with the ballast not powering up the lamp.
In case #2 the ballast would be fine because the lamp goes on while mounted in your TV, so here you are likely to have a problem with the LCD itself.
In either cases I'd recommend to check with a professional and maybe one that can diagnose the damage for free ad let you decide if you want to proceed to fix your TV or not
Good luck! :)

Tv went grayscreen, flickering. turned off, then


When you had gray screen and flickering you had only one problem - color wheel. After "putting everything together" you have totally different problem, caused by multiple possibilities like: forgotten connectors, cut/jammed cables/wires, lamp not being inserted properly, lamp door not being set properly, disconnected color wheel, etc. Try to open rear cover and redo what you have done. Remove optical block, check everything visually and slowly put everything back. If still no luck - then only skilled TV repairman may (or may not) help.

My Olevia 26 inch LCD works for 2 minutes then screen goes out.


It is most likely the Inverter Board. You can buy them online. The Olevia company got bought out and the only way to have them repaired is by sending it in to a repair shop and they have to send it to this company that is repairing the Olevia models (this is the ordeal I had to put up with) I asked him if I could send it to them but he (in an indian language I could hardly understand) told me I COULD NOT. It is a joke. I repaired my 30" (LT30HV) with the inverter board I bought here ( http://www.lcdparts.net/InverterDetail3D.aspx?ProductID=2510 ). It was $149.00 and they have instructions and pictures on how to repair it. You will have to have basic electrical knowledge as to what goes where when you put it all back together again. Other than that, it took me about 35 min (had to figure out where all the screws were) to take apart, 5 min to take the bad board out, 2 min to install the new one, and 15 min to put it all back together. Good luck

Did you replace the fuse with the same rating? some other component- possibly a capacitor may have caused your problem-either way your 5v stnby light now goes off and still no power to the tv its your power supply- was the tv still plugged into the wall when you replaced the fuse?

Open the back of the TV,and look at the can shaped items on the boards.If any of them have the tops,or bottoms bulged out,they need to be replaced.This should get it working again.I hope this helps.If you have any questions,please let me know.Thank You very much!

Syntax LT30HV


I know it's been a long time since people posted here but the answer is an easy one. On the inverter board you will see a chip that says "OZ960" on that chip you need to solder an led from pin 10 to pin 16. I used digikey's part number L10041-ND. I could get into the technical reason but this fix does work.
