Kv 40xbr800 Wont turn on, I read your solution, who can I get to do this for me in Miami

Do what I did. Look in your local yellow pages for any television repairman who is familiar with Sony televisions, in particular, one who has worked on these particular models.

My local repairman felt confident that it was related to an IC power reg. (I don't know what 'reg.' means, he just wrote that on the receipt). I've looked through various web sites & I've become aware of D-board problems associated with this model(s). A D-board is essentially like a motherboard (just like in computers), and this particular circuit that is bad is like a little chip located on the board. I'm not an electrically inclined person, but at least I've done a little research before I hired this local repairman.

Anyways, I had him replace the integrated power circuit (part # MCZ 3001DB), which required removing the existing, soldered one & re-soldering the new one.

It has been working w/o any problems since he replaced the part. Although it has only been 5 days since, again, the repairman was confident that was the problem & that it should last for quite a while (hard to predict really).

The bottom line...it only costed me $123, which included him coming over to my house instead of me lugging the impossible! It only took him approximately 30 minutes total.

Anyways, do some research...you may be lucky that it the cost of repair is significantly lower than buying a brand new LCD from somewhere...

Good luck!
