AM FM radio Compact Disc player o.k. for 30 sec after start, then nothing. Fuses o.k.

Maybe a shorted speaker causing the power amplifier inside the radio to shut down or a speaker wire shorted to chassis and last the internal amplifier of the radio cd set faulty by itself... set volume to zero power it off take out the radio cd set; remove the speaker iso plug leaving the power plug only in and power it on if necesary turn again the volume down to zero and wait if it keeps turned on it a speaker problem if it shut itself off again then you go for a repair or a new one

Wharfedale LCD2710HDAF no power to tv, checked cable and changed fuse a few times, new power lead? or is this a common problem?

Hi.

The power cord must be checked using a multimeter. The test is done reading impedance (ohms) between plug's prongs and contacts to TV power board.

If the power cord is OK and there is no power, then the problem is the power board inside the TV.

Regards.

Ginko.

It's broken. I have a couple on my bench with this fault and they're not worth fixing when you can pick up replacements on Ebay for 30 quid.

NOTE: This is a really common failure mode. You're just unlucky it happened outside the warranty.

My Bose Wave CD Radio has no power. Will not turn on. dead. Checked the power cord and supply, it is good. Is there an internal fuse?

Yes - although Bose doesn't really publicize the fact, there is an internal line fuse in each Wave. Location varies by model and date of manufacture, but the fuse is easy to spot once you open the radio case.

Water spilt into top of wave radio cd system and it is dead

Bose radios do not have an integrated fuse link. the water has shorted the main board. the best action here is to, replace the entire unit. this can only be done by sending it in to bose. i understand that this is not the option you wanted but, all replacement boards and internal components are not available for consumer purchase.

This repair or, exchange can only be initiated and completed by the manufacture(bose).

My wharfedale lcd42f1080p just went bang when plugging it in!!

Sounds like something else in the power supply. The surge inrush current could have blown the bridge rectifier. (device which changes AC to a pulsating DC for the power supply). You may need to have the power supply serviced or replaced.

37 inch LG LCD won't turn on due to power failure

Power failures can cause all types of problems, have you firstly checked the fuse in the mains plug? If that is ok then it may have blown an internal fuse in the power supply board, these are there to protect the rest of the circuit from power surges.

Problem

If the AC power source (outlet) is ok and the line cord and fuse are ok but the unit is completely dead, you may have a problem with the internal switching power supply.

Locate the switching power supply and see if there is a fuse on its circuit board.

Completely dead units are typically caused by a failure in the power supply section.

Please let me know if I can be of further assistance to you.

Good luck!

Cold solder issues - each component is soldered into small holes on the printed circuit board which in turn connects said component to the other components. Due to time, heat, use, some solder joints would be cracked or loose. It is possible that the cold solder is still minimally connected (hanging by a thread). When the receiver turns on heat would be generated which would be sufficient to further loosen up the solder joint to the point it no longer provides electrical contact. Jarring the unit creates movement inside enough to re establish the contact, sometime good enough sometimes not enough.

Again, since the unit still operates (sometimes) then it is highly probable that there are no defective components. As you have surmised, it is possibly a loose connection, solder joints are "connections" except that molten soldering lead is used to attach/connect the component to the board, "loose connection" in this sense is equal to "cold solder".

Again on the assumption of no defective parts, then seeking a more experienced buddy for the soldering might be to your advantage. This is of course in addition to the possible electrical hazards when repairing....If i have helped,please click fixya.It is the only way i get paid for my work...
