Sony ZS-S2ip boombox no sound
Hello
I have a sony zs-s2ip boombox that has no sound output at all. I tried all the functions ipod, radio and cd and none of these will output sound. I plugged in headphones and I get no sound either just a faint buzz. It appears this problem is common as I saw someone on amazon complain of the same problem with this equipment. What tools can I use to diagnose this? How can I diagnose this problem? I opened the boombox up and the motherboard capacitors look good. Your help is appreciated. Thanks -

Asus eeepc mini laptop display issue
Hello
I have an asus 1000he eeepc mini laptop that turns on however I get no video. The power status indicator lights turns on so the pc gets good voltage and turns on howeer the battery light is blinking slowly and orange which means the the battery level is between 80 and 10 percent. The hard drive led is off meaning the hard drive is not being read. The wireless light indicator is on meaning the wifi is enabled. What could the problem be? Could it be the Gpu needs a reflow? Could it be a motherboard issue? Does anyone have the service manual for this laptop? I am going to check... -
Re: Imac g5 video display issues
Hello I am writing this from an imac g5! I reflowed the gpu or graphics card/ graphic chip on the logic board for 8 minutes with the hair dryer. So far I have been using this computer from about half an hour ago without a problem. Knock on wood.Leave a comment:

Re: Imac g5 video display issues
So this time I tried the reflow again however with a hair dryer and heated the gpu for a minute from 4 inches away and then i heated the gpu for 3 minutes from 1 inch away. I placed aluminum foil around it so the capacitors and other stuff doesn't get too hot. I reassembled partially and guess what led 3 came back on and got to see the video. I turned it back on after I reassembled totally and I got a good 3 minutes of video out of it until it went out again with the same problem no video. I guess the reflow worked only for a little while. I will...Leave a comment:

Re: Imac g5 video display issues
I tried the gpu reflow to no avail. I heated up the gpu chip on the logic board with a soldering iron with some aluminum foil on the tip of the soldering iron. In the gpu reflow, the only thing you apply heat to is the black ceramic piece on the bigger green chip or do you apply heat to the green part too. I put her back together and now i still have led no 3 off however led 4 is on so its overheating and it turns off after a minute.Leave a comment:

Re: Imac g5 video display issues
PSU is giving voltage correctly as diagnostic leds 1 and 2 are on on the logic board.
Yes I hear the apple chime when I start it up.
Tried booting from cd, it doesn't boot from CD. I tried holding down the c key however I still get no video and fans start roaring after a while.
It has rubycon capacitors and they show no visible damage.
The overheating led is not on so its not overheating.
I am leaning towards bad soldering on the gpu. Perhaps a gpu reflow with a hot air...Leave a comment:

Imac g5 video display issues
Hello,
I have a 20" 2.0 ghz Imac g5 rev b with ambient light sensor model number M9845LL/A.
When I start it up it does not boot and I get no video and the fans are roaring loud. The third diagnostic led doesn't light up on the logic board meaning the logic board and the lcd are not communicating. I tried connecting an external display and the external display gets no video from the Imac g5. I have heard of the bad capacitors problem on the logic boards however the capacitors show no sign of visible damage on the logic board, they capacitors aren't leaking or even swollen...
