Ok clicking tends to a relay trip do to over power caused by a dead fuse. unscrew your tv after you unplug it look at the board pull the fuse and replace its usually says like 250v blah blah blah and that should do you if that doesn't do the trix then it may be a blown compacitor wich you can't fix your self, unless educated in soldier repair.

If you still haven't thrown the set away . . . The ticking noise can come from different sources; either a relay that is tripping so the set doesn't burn your house down, or the horizontal output transistor is shorted shutting the set down, or there are failed components in the power supply.
I'm not sure which 'line transformer' you suspect but it isn't a likely place to look for this problem.

No power ticking sound when plug into outlet


Hello

Your Philips Tvs line output section has some trouble with it. All philips power supply circuits are so designed that, even a small short circuit in the ciruit board occurs, the power regulator will sense it, and the entire system will shut down, and that is happening now in your TV.

You just start with the horizontal output transistor, fitted very close to Line Output Transformer [LOT], for any short. You must desolder it out from the circuit for this check, and check it for collector to emitter leak. If this will happen, the main regulated power supply ie 120VDC, will gets shorted through this transistor, cause a dead short circuit. If it is shorted, you must find out the reason for that short.

If LOT said above has damaged, this transitor will also get shorted. In otherwords, if LOT is damaged, its driver transitor,will also will get leaky. You just replace this transitor with an identical one. Switch on the tv for a while, say 10 seconds or so, check its heat effect. If it heats up abnormally, surely LOT has damaged, and you should replace it also with an identical type and number. Ok

My philips ambilight wont switch on i can hear clicking noise and red standby light keeps flashing any ideas


U have tools like a soldering iron,desoldering pump or roll of desoldering braids,a roll of solders and understanding basic electronic also can do basic soldering?This problems,most of the times are causes by those dying soon to be dead components call capacitors on the power supply board.Yes,take ur tv aparts,the power supply board,that the board,where the power a/c cord plug into it.Check the power supply board for those dying soon to be dead capacitors parts,it alway bulges up on it tops or puffing up on it tops.Replaced these dying soon to be dead capacitors parts,will solved ur tv noises clickings,power LED light indicator will stop flashing.Tv will power up normal again an work.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Tv will not start, only a thin vertcal pops on than off


your tv is trying to open up but its being chocked down.
let the tech check if the out put is being produced from the power supply to the line transformer of a bout 95v - 115 in some tvs, and this should be there all the time you switch on a tv. and that produces a sound like a snake in side the tv, firslty you should check a power supply.
okay

My tv wont turn on when i push the power button it ticks??? what coud be worng


if your tv is not powering on, firstly check the switch contacts, rectifier diodes, power trsnsistor, fusible resistors and zener diodes. all these components are at power supply section.

make sure that a HT voltage of 90-115v, shows at the line transister near the line transformer.

note-----a tone be head on the supply.

Dead samsung 172n power light flickers


Have you checked the power output from the power board? Is it constant and steady? Try reflowing all the joints if you haven't already. Especially transformer and coil joints. Maybe a bad logic board? Do you have spares to try? Does it do this with everything disconnected from the pwr board (switch, logic, inverter)?

Tv won't turn on


Most likly it is a problem in the power supply regulator circuit. pretty common for Toshiba TV sets. If you know about TV serviceing, first thing to replace would be the regulator IC as that is the problem 80% of the time. if that does not help then you will need a schematic to trace out the regulator circuit. Good Luck PS please dont forget to rate this thread.

Please Help - Set "Dead" Euro 7 vp chassis


This sounds like a line timebase failure. The line timebase works at about 15 thousand cycles per second (15KHz) which may be audible to some people due to the iron-ferrite materials used (magnetostrictive). The line output transformer is highly stressed and also has the rectifier diodes in the outside if the windings. It is all very well insulated to guard against moisture and dust but if it breaks down due to the high voltages (25Kv) the arc produced makes this squealing noise, and of course it burns out, and breaks down. This may not blow the fuse if there is not a short circuit. So get an engineer if you are not sure about changing the line output transformer.
