Question about Panasonic Televison & Video
Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

the symptom is usually caused by a breakdown in the power supply circuit. in most modern receivers (transistorized and/or ic), it may also be caused by a breakdown in the horizontal deflection circuits (hor. oscillator, pre-drive, or drive circuits). supply voltages for the tuner, vif,sif, and vertical output are usually supplied by the horizontal output circuit. but if you doesnt know anything about these stuffs, better bring it to a qualified service technician

SOURCE: tv stuck in 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.

have you tried changing the batteries just to elimate this problem
sometimes if the batteries are low in electronic devies, they send a wek signal to its receiver (your tv),
your tv gets confused and then switches itself to standby
if you have changed the batteries and this problem still persists
it can only then be th PSU or power supply unit, take it to your local tv repair shop of mastercare somewhere like that, its going to be cheaper to get it repaired than replacing the whole tv
PSU'S generally 20 to 50 pounds depending on model
don't deo it yourself though unless you've got a capacitor discharger (or a nice 25KV will be on its way to your body)
hop this helps mate, let me know how you get on

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!!
