Hello guys,
I have no luck,after a long time I received a new inverter board for BEKO L6B LCD which is in my service and what happened....
after board replacement TV set works perfectly about 10 minutes and after that backlight switched of from self (sound stay and with remote commander you can change the chanels and switche of and on the unit).You must plug of from power the TV set and again on ,now back light is present again and picture also but for shortly time and so in the circle.

In the previous inverter board defect was one inverter transformer and his driver IC.

My question is can be the cause for  one back light bulb in LCD panel ?
Can someone provide me with an address (where can I buy ) for
BACK LIGHT BULB TESTER .I have saw this small unit somewhere on internet but forget to save the web page.I only know that this small checker is made in England.
Using is very simply - conect the bulb cable in the checker ,switched on the checker .On the unit there are two leds one red and one green.If the red led light bulb is defect if the green led lights bulb is OK.
I think that this checker is very usefull becouse you can check the bulbs before order the inverter board.
If someone have some experience with this checker please to share it with me.
Many thanks in advance for help
Regards
Peter

Thanks for your suggestion but I live in Serbia and I very well know what ASWO have and offer.This back light bulb checker is made from some guy here in England.I have saw this unit on some web page but I forget to put this web page in my favorites .After a few days I cannot find this web page more.
Therefore I put this question on this forum (this forum is from England and there are many guys who repair LCD's and maybe some from them something know about this checker).
Again many thanks for your answer.
Regards
Peter
