I have a widescreen CRT Sony TV, it started to click only but would not turn on, almost like powering up then stopping. Is this the PCB?

Check to see if there is an alternate power switch, my TV has (2) power switches, one turns the power on but not the TV and the other turns the TV on as long as the power switch is on.

SONY KV34HS510 always worked perfectly but today it wouldn't turn on by remote or button on TV. It makes the same "click" sound which it always did before coming on but it just immediately clicks again to...


You need to bring it to a TV technician. There is a relay inside the TV which can be blocked by any few errors that may occur in your TV, for protection. Only a tech may discover the problem.

Sony tv wont turn on, standby light just flashes


check for an open resistor on the power supply, it is actually a fusible resistor, (white) if open, then check the converter, some sets have two separate and some have it as one. it will be on a heat sink on the power supply. if shorted then check for a shorted horizontal output transistor and repair cold solder joints on the horizintal drive transformer which is the real cause of this problem

Philips 32pw9527/05 tv does not start


Generally these type of problem occurs due to atmosphere contains moisture content. Even if it happens in warm area i suspect fbt leakage. Since this is high voltage transformer it can be serviced by qualified technicians only. Red light flashes indicates the tv in protection mode to avoid severe damage due to some short circuit. I think it is helpful to you

Sony Trinitron TV takes multiple manual clicks to turn on.


If you mean the actual mains switch needs multiple cycles, it could be faulty.. does anything, say a power indicator, come on when the TV doesn't?
If the actual switch is OK, then you probably have a fault in the power supply section... often faulty electrolytic capacitors. U need service.
