No sound


could be a setting that has the speakers turned off, could be a connection, or possibly your cable box has a problem. if youre running cable directly from the wall it could be a weak cable signal. you could always run the audio to a a/v reciever(surround sound, etc) just to get sound if none of the above apply

Power switch wont turn on,keeps clicking


The fault is not a relay, the clicking sound is just the protection circuit that prevents the TV from starting because a fault had been detected.

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Samsung DLP TV won't turn on


This sounds to me like one of two possibilities. First, check your ballast. If you're going through bulbs faster than you think you ought to be, you may have a ballast that is overloading. Its the 3" x 8" circuit board that connects directly to the bulb. They are plentiful and often cheap. Thats what I'd try first. If that doesnt' do it, I would invest in a new power supply board. That the board that the tv power cable hooks directly in to. This should give you a start, Comment back if you still need further help. Good luck.

Hi,

The most common problem with all 3 tube rear projectors is a damaged convergence circuit. The Samsung TVs are easier to repair than many others and the numbers that break down is not excessive. For every Samsung with a convergence problem there are a large number that did not breakdown. The fault is caused by bumps or noise in the AC power, not the TV design. This usually produces colored outlines around heads, etc.

Check out the Convergence Gallery. If you see the colored outlines or color shading as in the Gallery, you have a convergence problem.

This requires the replacement of the defective IC or ICs and any damaged or smoked resistors. Usually there is little alignment required after the repair. If you play with all the adjustments before the fix, hours may be spent re-aligning.

Don't monkey with it.

This is a delicate and difficult repair. If not done by someone with some electronic repair experience, the TV will likely end up as junk or cost considerably more for a tech to fix the damage done.

If you live in Calgary, call me. If elsewhere, find a competent tech.
