Title: Bush no picture issue
Post by: chammyman on March 23, 2009,19:42:08

Got a Bush IDLCD32TV22HD, sound works, channel changes all inputs work, backlight works fine.

Everything is there except a picture on the screen, now I pulled it apart and I found what I beleive is a blown surface mount transistor. There is no question the component is blown.

The board is the board that supplies the LCD screen itself it has several ribbons off it to the screen. The board has HP321X00107AD68XS1T101DFAL on a small white rectangular sticker, the transistor is at postion 0300 on the board, I believe I can make out MO on the transistor but the other half is melted.

If anyone has information on the rating of this transistor I would very much appreciate it so I can obtain a replacement.

Also what is the likliehood that this is the only issue? I have checked everything else over carefully and nothing else is blown, or damaged, no swollen caps etc etc, everything else seems fine. But I don't want to replace the part or get another board for it only to pop again right away.

Thanks in advance.

I assume pictures of the actual board would perhaps help more?

Hi Cammeyman,

If it is the screen driver board, then you normally have to buy the screen to get the board!
That would obviously write the tv off.
Your best bet might be to look on ebay to see if any one is selling one with a broken screen and then you will have a spare set of panels as well.

Hope this is of some help
Brian

its the chi-mei screen the samsung board from what I have seen only has 2 ribbons to it and the che-mei has 4 smaller ones.

If you have a board tv tony that would be great.

Shaun thanks I will call them if tv tony can't sort me out.

Brian IO have been doing just that but none have come up, thing is when it gets fixed/binned then loads will appear
