hi, i was called by my grandmother to repair a 21" sharp tv. The problem was there was an intermittent sound. the tv reception and picture was fine. I inspected the PCB and resoldered many cold solder joints. Turn it on, but the problem was still there. So I prod the back and pcb and while gently pressing the back portion, the sound come back. Releasing it makes sound disappear again. So turned off the TV and examined the PCB. I found out loose solder joint on the jungle ic (X2701cen1). Resoldered it but when I turn it again, its always in the standby mode (led red). Its not turning on. the relay clicked and then clicked back. No high voltage at all. So I look for another technician to look for the problem which I made and he said that it was the jungle ic which is defective. I pointed out that it was the last thing I resoldered before it failed to turn on. Id like to hear from your suggestions to check further this set before i buy this ic. I think I fried the ic. can you give me some tip in soldering ic. I realized i became careless. Because the other technician told me that I should have discharged first the capacitor before poking on the ic because it was so sensitve. I knew many precautions, but I havent practiced it for a year already.sorry
thanks,
Ian B.
