What's your question?my PCB have got a problem when I look closer I see a head sink on the board they is an ic that bust so I need that number of the ic but it see like it start with T


Although it may be done, i think replacing the circut board rather than the ic would be the answer to this one. Even if you have the equiptment and the skills it takes to succesfully replace the ic, chances are ,a critical circut malfunction occured damaging you chip. The same result may happen again with the new ic.
I would consider pricing either a circut board or a new display all together.

Hln617w1x/xaa keep shutdown in 5 to 10 minute,picture kind of bleeding??


Its a common problem. The lamp needs to be replaced.

Call 1-800-samsung & choose the parts dept.
For the replacement lamp it cost $149.99 plus tax & shipping .
You give them the lamp code ( red sticker on the side of the tv) , they send it out 5day shipment.
Local tv repair services can install it for an installation fee. This will save money apposed to ordering through a tv repair shop who charges an order part fee plus etc...

Are you looking for the Ballast for that model? You should be able to google the model number with the word ballast after it and find it with ease.

It is a nasty game where they don't sell parts, just the entire board.

I am here to give you as much help as possible.

My t.v. shuts off


Hi,
Please check basic things first, like first of all fuse is it OK, then check the power supply mainly the big one capacitor in power supply, if it is popped then replace it, further check voltages of main power supply, if you have proper tools and digital meter along with solder iron the check the voltages accordingly, the problem is in power supply unit. And if you can not do this by yourself then please call any expert nearby.
Thanks for using fixya.
