hi guys

this tv keeps not switching on then its fine,the voltages seem fine but one thing ive noticed is that at the top of the invertor board i can hear a buzzing sound so im wondering if its the panel that is at fault ?

thanks

Not switching on? Symptoms?

No power light ?
No backlight, no sound ?
Backlight, no pic, no sound ?
Backlight, no pic, sound ?

Checked any voltages...?
BN44-###### number from power board and pin voltage diagram can be located

Cold joints are a common issue. Also can be bad startup cap.

Many inverters do buzz in operation, but if there is a bad smell or the buzz seems intermittent, like electrical arcing, it could be the lamp wire in the screen arcing. Fixable, but you need to take panel to bits.

A buzzing sound at the top of the inverter? Is it coming from the transformer or one of the caps in the area? Doesn't sound like a bad panel.

Re: Samsung le37c530f1w

right symptons it will go into standby occasionally after using the tv and sometimes take a few attempts to turn it on after unplugging it a few times
im testing for cold solder joints now and checking if any caps are faulty

Re: Samsung le37c530f1w

So when faulty, power light is LIT? Does main board respond to remote, e.g. with blinking light when you press a button?

Re: Samsung le37c530f1w

ok just had the fault the tv basically goes into standby then turns back on,and yes the main board responds with remote

Re: Samsung le37c530f1w

OK, start by heating parts of the power board & see if you can make it go wrong. Check power supply voltages and for any cold joints or obviously bad capacitors.
