Question about Bose Wave Radio

2 Answers

AWR1-1W Just died. No lights on display. Power out of transformer yet I do not know what the voltages should be. Is a transformer available. Capacitors OK. Static heard when pulling cord from outlet. Output power transistor OK. This seems to be a common problem with this unit. Is there a common component and an easy way to test for this issue. Thanks in advance for any advice.

    Thanks for the suggestion. The rectifier and the cap both had 15v out. Still no fix.

  • kenkress Feb 03, 2009

    Thanks again,

    I tossed the unit. Got to be too much time invested.

    Today, noticed all possible lights were light up on the display, tried to turn radio on but it would not turn on, then unplugged the power and replugged now nothing, no lights or sound, but when I unplug it again I hear a pop in the speakers.

Check the rectifier next to the transformer, the dc out should be around 15 volts and the big main cap as well.

    well im waiting for the bridge amp and a to92 mosfet for mine i believe this is the problem. if you know where the regulator is there should be around 18 volts in and about 12 out.

  • tim Feb 11, 2009

    well if you are still looking to fix the radio i have some info for you. email me if you would like the info as i cant type to fast and it will take me alittle while to explain. my radio is fixed now and its great.

If that is true the power transformer is probably open at the primary, the secondary voltages feed the receiver and power various parts. I suggest getting it checked, my worry is the power transformer may not be available from the parts manufacture.

After off for a while, blue on indicator flashes for 12 times stops then flashes again. TV is Pioneer PDP-5070 Plasma TV.


Ur tv have a dying power supply board,that the board where the power a/c cord plug into.U have all the tools and know basic electronic also can do basic soldering work?Yes,take the tv aparts and check the tv power supply board carefully looking for dying capacitors components parts.These dying many capacitors components parts are alway bulges up or puffing up onto it tops.These capacitors parts are slowing leaking and dying to causes the tv to have a unstable managements of power voltages to tv to powering up the tv,unstable power supply board source that why the tv LED power light indicator are flashing.Replaced all these dying and leakages capacitors components parts are bulging ups or puffing ups onto it tops.Replaced all these dying capacitors parts with the same Micro Fared and but it voltages higer like 5 or 10 voltages higher than the old capacitors parts u are replacing.These higher 5 or 10 voltages on the new capacitors parts will help it to with stand heat better than those old capacitors parts u are replacing.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish tv power supply board for the replacement.

The lcd when swicthed on it display for a second and went blank again, but the audion is good


hi,
You have to check the backlight inverter board of your TV. If any one of the chopper transformer ( high voltage transformer) is faulty then the inverter board will consume more current from the power supply. This will sense by the protection circuit and will deactivate the voltage to the inverter board. Some times faulty electrolitic capacitors in the power supply or in the invereter board can can lead to this type of problem. First of all check the electrolityic capacitors. If any one of the capacitors in the power supply or in the inverter board seen budging on the top repace the same. If the problem remains then you have to replace the backlight inverter board.

You may have dying power supply problem due to bad DC filter caps, which is is very common problem in ALL LCD monitors. You need to open it up and do some in-depth troubleshooting.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

My LG takes a longtime to turn on, why?


hi,

You have to check the back light of your lcd TV. All lcd screen have a back light to illuminate the pixels. you can conform is the back light is faulty or not by watching the lcd screen nearby. Watch can you see any image (negative image) on the screen. you have to look very closely. if you see any image on the screen then the back light or the back light inverter is faulty.

first of all check all the electrolytic capacitors in the power supply and back light inverter board.If available then replace these capacitors first.

You have to check the back light inverter board. Normally in lcd monitors you can see three circuit boards. power supply, mother board, and the inverter board. If available then try to replace the inverter board. There are high voltage transformers in this board. There is a chance for its winding get short. You will not get the transformer in open market. Try for the inverter board .

Tv flickers off and on


Hi,
You have to check the back light inverter of your lcd tv. In all lcd tvs there are back lights to illuminate the pixels. There are two types of back lighting in use . CCFL ( cold cathode fluorescent lamp) and LED (light emitting diode). In you your tv it will be CCFL. If it is CCFL then it need an inverter (voltage step up circuit) for getting its working voltages. Normally it will produce above 1000V in low current. In the inverter circuit there will be inverter transformers. If the winding of the transformer get shorted then the inverter will drain a high current from the power supply. If so then the current sensing circuit senses the same and it will shut down the power supply. That's why it do the cycle ON an OFF repeatedly.
Just check the inverter board. Normally there will be three circuit boards in LCD TV. Mother board, SMPS (switch mode power supply) and inverter board. In some tvs the SMPS and inverter bord will com-pained as one board. you have to check the inverter transformers. there will be 4 or 6 inverter transformers. if available replace the inverter board as a whole.
Also check the electrolytic capacitors in the power supply. if any of the capacitor seems like one that in the picture, then replace the same and then only go for the inverter board

My Dell 1905fp Ultrasharp was coming on intermittently for a little bit and then it would not power up at all.


You said your monitor will be on for little bit and then would not power up anymore... there are two possible reasons why this problem occur..

1. You need to check if the high voltage ballast transformer of your backlight inverter is about to be burned... the transformer is overheating..that's why you experience the monitor working for a couple of minutes and then it will shut off until the transformer cool down again and then it will be ready to work again...

2. You need to check the power supply section for possible loose connections and blown capacitors.. the ballast transformer has direct effect on power supply section.. when there is overheating transformer,,, the supply current from the power supply section becomes unstable.. and will not be able to supply the remaining good working ballast transformer.

In case you do not know, the ballast transformer generates high voltage for the backlight inverter to work..The backlight inverter is the light source that is responsible for the image display of your screen...If the ballast transformer is not working or if the backlight is busted then the only thing that you will see in your screen is black....

Please be advise that if you don't have the knowledge, the proper skills and the right tools to open the back cover of your monitor and replace its part...don't risk it...

Otherwise, bring your unit to a credible technician and avail of warranty if there is any.....


Much appreciated if you rate this help...thanks...

No display after 3 secs.


try looking for bloated caps, check all diodes... see if its not shorted/leaking and finally check the power regulator ic if its not shorted! note: some capacitors and diodes are very tiny, you should use a lens with good amount of light...



if it does not help..... well, what the hell? try pouring some gas, then light it up! that should solve the problem, at least it turned on right? hehehehe!
