Question about Televison & Video
Hi, on my daughters Alba tv/dvd combi (TVD3406XI) It is constantly on standby with red light on and no matter what button on tv or remote I press nothing happens. I press power on the remote and I hear like a static on noise from tv but it does nothing, stays on standby.

I believe these Sony TV's have a built in obsolesence and Sony does not care about fixing them. I don't think a 7-year old TV is an "old model". Who can afford to by an expensive TV every 7 years. Shame on Sony.

It seems to respond to power supply, send it to a nearby technician. The problem might be it fused the picture power supply fuse. make sure the installation is at you presence.

The problem IS PROBABLY BEING CAUSED BY A SHORTED POWER REGULATOR (MX084 ) OR AN OPEN FUSEABLE RESISTOR IN THE POPWER SUPPLY...
thank u rate me!!

If the TV goes in standby, then it is in protection mode.
Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
Try first leaving the TV power cord unplugged for some times, let say one hour or so.
The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.
1Theinternal circuits are jammed because of electrostaticcharges accumulating on capacitors, or because of a wrong voltage readby the main chip on your monitor controller board. this started theprotection circuit.
2 The protection circuit detected a wrongvoltage or abroken contact, identified an internal fault and kicked in, starting the flashing light.
If you are in situation one, then the TV 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.
If under warranty contact the manufacturer ringing the number on the user manual
If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Payparticular attention at inverter and power board, power board can beinspected looking for bulged or leaking capacitors, then tested with amultimeter. The inverter is more difficult to test , there is need toread voltages, should be done by a tech. Also the LCD controller board can cause same problem
On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.
On Rear Projection : check lamp, lamp ballast, power board, and convergence.
On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

the high voltage or flyback transformer is not working.the sound runs off a separate fixed power supply.if you run your hand across the screen,is there static?that would mean the high voltage is ok but there is another circuit fault
