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.

No picture or sound


Dear belladionne1,
Unplug TV from a/c outlet for 2-3 minutes...plug back in. Turn TV on; do you hear any clicking sounds (relay)?

NO: Check voltage on pin 1 of IC702. No voltage, suspect IC709 (5 volt regulator). The IC is on the PCB- Signal, part number 266P922010.

YES: Suspect Vertical IC, IC401 on deflection PCB( the one on the right. IC located towards front of board, on a heat sink, standing up.

These are the MOST common failures for your Model VS-585R.

I hope this was helpful, big IRISH.

FIRST CHECK CONNECTOR "DR" FOR PROPER CONNECTION, BETWEEN THE DEFL MINI PCB AND THE MAIN PCB. 2. CHECK C5A09 AND C5A50 BOTH 33 UFD 50 V OFF OF IC5A01 ON PCB-DEFL MINI. 3. CHECK FOR LEAKY IC5A03 PART # 270P704010 ON PCB-DEFL MINI 4. SUSPECT THE HIGH VOLTAGE BLOCK PART # 920P016010 IF STILL NO HELP PROBLEM CAN BE INTERMITTENT (TEMPERATURE RELATED) CAUSED BY IC7D04 PART # 275P245010 ON THE DOUBLER PCB THIS WOULD BE A THIN VERTICAL LINE IN CENTER, IF GUNS WERE ON.
