Wharfedale DMP82 mini hi-fi unit. It's stuck in standby. When the standby switch is pressed, the display lights up then goes back to standby. LCD display is on as the 5v line is still present. The 2 x 14v lines are at 4v and rise momentarily as does the 12v line. The standby line is 0v then rises to 2.5v when the switch is pressed. Not an easy unit to take apart and I've only managed to get the back (PSU) off. Any ideas?

Hi, I have a 42 inch NEC plasma tv I purchased about t years ago, about 6 months ago every now and then the sound would become slightly distorted like a swishing noise shortly after the tv was turned on. Now recently the sound does not come on at all when the tv is switched on. If the tv is left on the sound may come on eventually by itself after around 30mins till up to 3 hours after being turned on. And on occasion the sound will come on straight away when switched on. The are no other issues

When the Power on button is pressed, a GREEN blinking light (5th light in a row of 5) comes on and blinks about 58 times, along with an intermittent "popping static" noise.

Vizio VO370M will not power on. Vizio log stays yellow when power button pushed. Problem occurred following lightning storm, so suspecting the PS, but not certain. No physical damage apparent to either the PS or mainboard (fuse is good, no bulging/leaking caps, no burned spots, etc.). When testing PS, 5v connectors supply good 5.3v. 12v connectors have no power, but not certain if they always supply power or only when switched on. Is this more likely to be the PS or the mainboard?

When switched on, the power light flashes on and off on the front of the TV but no picture. We have the back part of the panel off and there are no puffed capacitors. Everything looks good except some goop around some of the capacitors. Is it normal to have goop that looks like its flowing out of the caps? Is it a glue that helps it seat better? I have access to a multi-meter and have the checked the output of some of the connectors. Anything to suggest?


It is not normal to have goo coming from the cap. Usually a cap will pop and you'll have the top or bottom puff out. Sometimes a cap will explode and you'll have a little more of a mess. So if it looks like goo is coming out if it then that is probab ... Samsung PS42B430 42 in. Plasma TV

My television is just over 2 years old and it started that it would switch itself on and off 3 times before it would stay on and it was randomly switching itself on if I didn't need it to. I phoned the Samsung support line and they told me to reset the television which has only made it worse! It is now taking around 2-3mins to switch on and that is only IF it switches on. Then around 5 mins in it will switch off then stay on. Please help!!

No 3.4 volt output


The 3.4 should be for the microprocessor area and comes from the standby portion of the power supply-----that voltage should be on all the time so look carefully where it comes from---some sets use a op-amp IC to switch it on etc and others a relay-- ... LG 37LP1D 37 in. LCD Television

The TV seems to take ages to turn on, the red on/off light flashes and then goes off completely and the screen stays blank. It then switches on again and after a few seconds/minutes will switch back off. Eventually it seems to warm up and stay on. On occasion it will take up to 10 minutes for the TV to warm up and switch on. Once on there is no problems. I have not tried fixing this as I feel it may well be a job for a qualified technician. Please advise if the TV is safe to use, and what's need

My tv (AOC LE22H037) automatically lowers the volume down to zero. it depends on what kind of sound is it outputting: during movie whispers or song's almost silent intros, volume gets lowered down. its annoying because i always keep missing the first 2 or 3 words of any line. it is like, if the tv "senses" silence or almost silent sounds, it shuts down sound output. But if the input sound is continous, like in the middle of the song or the shooting of a submachine gun, output volume remains cons
