Question about Sony MHC-GX45 CD Shelf System

1 Answer

Power light only flashes

Power light only blinks repeatedly on/off when I try to turn it on even after I unplug it. Happened suddenly. Same results both with remote and turning it on via the console. Is it dead, memory erased, or other?

    I unplugged it for several hours, came back, it's now working, but I expect this was not a fluke, and am prepared to take it in next time this short happens, good advice, thx.

No that is the unit telling you I am shorted so I will not turn on as it could cause a fire. Most likely there is a short in the audio output amplifier. This unit will need to ba taken into a repair shop and diagnosed. Good Luck

When I attempt to turn on the TV the green power light will stay on for about 2 seconds. Did system reset with paperclip, timer light flashed for 1 minute. Tried again with same result.


STANDARD ANSWER FOR THIS PROBLEM:

MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ONFOR A MOMENT AND GOES OFF.

PRESS AND HOLD "device" and "menu"buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protectthe Convergence IC or IC's is blown---set will detect no voltage to convergenceIC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES ANDTHEN TO GET IT TO REPEAT MORE YOUHAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

let me know what you find--hope that you find 2 blinks, a pause and twoblinks--this is the most common and easiest to fix.

BEFORE YOU RATE THIS INFORMATION LET ME KNOW WHAT YOU FIND, i AM HERE TOP HELP.

The power light is constantly blinking in yellow. before this happened the yellow light was on without blinking I turned it off, once I turned it back on the light turned green but the screen...


try unplugging your t.v for 10-20 seconds. plug it back in. if your power light continues to flash your t.v is the issue. you should be able to google your issue or check your owners manual about the problem. unplugging the t.v is the last ditch effort. Good Luck!

Sony Bravia KDL 46", no picture, standby light blinks 4 times


Since the TV is still receiving power, the problem is going to be with the TV's mainboard.  After you unplugged the TV and plugged it back in, you said the power light went out again, so I assume the standby light wasn't flashing again?  The flashing standby light is indicating an error code so my suggestion is to contact Sony for service options regardless if there is a warranty or not because service is the only solution to this situation.  Don't forget to provide them the error code or 4 flashes repeating.

HITATCHI ULTRAVISION P50S601...POWER LIGHT BLINKING...WONT COME O


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.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


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.

Green power light will not stop flashing and tv will not turn on or off


You need to replace the 1000uf capacitors on the DM board thats the classic symptom of the DM caps being bad the light continues to blink repeatedly. If you need more info on the repair let me know.
