    The tv is made by a company called Harwa,they seem to be based in Germany.

    It is a 20 inch TV ,there is not to much info on the tv itself just

    Model LC-20H3SW.

    Can you supply me with an invertor pcb and maybe a hints on how to fit it?

    Hello,i have taken a photo of what I believe is the invertor pcb board

    it has the following info on the board BL200601I,

    It has 6 pairs of wires(3 on each end of the board) one pink the other a lighter white cable. It looks a fairly expensive piece of equipment.

    I tired to add a picture but it was to big,but the board is as you described

    I attach photo of inside of TV ,is it the invertor or do I need to dig deeper?

Your problem is very lightly to be A faulty invertor pcb.
Relatively easy to replace but you may find it difficult to purchase.

The invertor pcb basically makes high voltage to strike up the tube lights behind the screen.

What make & model is your tv set & what country are you in.

    Remove the rear of your tv set.

    Im not at all familiar with your make of lcd tv but most invertors are on the left hand side when viewing from behind.

    It will be A rectangular pcb 3 to 4 inches wide it will have pairs of wires going to evenly spaced plugs these wires are normally PINK & WHITE & the texture of the insulation on the wires will be very rubbery & feel dense.

    You may need to remove other metal shielding or Pcbs to gain access so be very carefull when unplugging any plugs from sockets make notes & take pictures as you go.

    If you decide to have a go once you get at the inverter board write down any numbers & names on it. EG, DARFON, TOKO,SUMIDA,

    Once armed with the numbers try this site

    They will sell to generall public.

    If you cant see invertor board when you take off back of tv take a picture of the set & post it on here So I can see where invertor is.

Tv fades to black very low sound or or goes to blue & says lost siginal then goes toblank turn off set & waite a few min.& turn back on will only stay on for a few min. have to repeat.

This is not a "digital" problem that can be addressed in your setup or fixed at home. This sounds like a fading power supply. Often electronics fail slowly or partially.

You will need to consult a TV repairman.

I hope this helps!

My Vizio LCD TV screen fades to dark. Sound stays on.

I w having this same issue when watching a Blu-Ray disc. I found it to be dependent upon what picture mode the TV was set to. By this I mean certain picture modes would cause the TV to dim during dark scenes of a movie. Changing the picture mode helped a lot.

Lcd tv picture problem

My 3 yr-old 30" Olevia LCD HDTV lost picture after being on for about 1-2 min. Does any one encounters a similar problem or has any suggestion as to how or wherther it can be fixed. Thanks.

Picture faded to black, came back, faded again and had stayed black.

It seems your set has a loose conection in the high voltage circuits,in fact by now it should have many loose conections in different areas like the power supply and the horizontal deflection circuits,if you are familiar with tv service you can use the information as the first step to take,some of the loose conections are hard to see even for the trained technician but the one giving you this problem should not be hard to see,if you are not too familiar with tv service be safe and call for assistance from a servicer a least for an estimate.
