Question about Sony KP-53S75 53" Rear Projection Television

1 Answer

No picture, TV dead and the relay on the power suply cliks once

The Power led blinks 4 times when I turn it on, but the TV stays off, like dead. And opening from the back, I could hear a click coming from the power supply of the TV. I replaced an IC MX0541B, two transistors in one circuit shorted, but still doesn't come on.

We have a 2007 Sony Bravia 46" KDL-46VL130. There is not sound or picture. When we power it on the green light comes on blinking once and then the red light blinking once and then the green light stays on....


Does the front light stays green ? Or goes back to red ? The back-light going on/off maybe the problem, but it shoul return with a red blinking led (4 times ?) and if so it can be a power inverter problem.

My tv wont turn on.it sounds like its going to but


The 7 blinks are an error indication that is generated by protection circuitry inside the set. A problem has been detected and the set is shutdown to prevent further damage. The cilnking is the power relay that is attempting to turn on the set. I'll look up the eror code and update this with the likely solution later today.

Enter codes for remote R55L8-RCR4358


There are 4 ways to program your remote:
-Brand Code search and entry
-Direct code entry
-Manual Code search and entry
-Auto Code search and entry
*ON TV/VCR(DVD) combos you must program each button individually and that button(ie. TV or VCR/DVD) will program that part of your device.
*the DVD/VCR button programs DVD by default, in order to program it for VCR you must put it into VCR mode:
1.hold down the DVD-VCR button-->the red led will stay lit.
2.while holding down the DVD-VCR button press the number 2 --> the red led will turn off
3.Release the DVD-VCR button--> the red led blinks 4 times and turns off
4.The DVD-VCR button is now set to VCR mode-->program for VCR

BRAND CODE SEARCH ENTRY:
1. turn on device
2. locate brand codes(sorry, I don't have it, try finding genaric RCA codes)
3. hold down the component button--> led should stay on
4. while holding component button, also hold power button--> the led will turn off, then after 3 seconds it will turn back on.
5. release both buttons--> led will stay on
6. enter brand code--> led blinks once
7. press power button repeatedly until component turns off-->each time you press the power key the remote sends a different code for that brand. led blinks once
8. if power on your device turns off press the stop button to save configuration-> led turns off
9. if the led blinks 4 times and turns off, you have reached the end of the codes for that brand, try using a different method to program your device.

DIRECT CODE ENTRY:
1. turn on the device
2. locate your device codes
3. hold component key down-->led lights up and stays lit
4. enter code while holding components key--> as first key is pressed the led turn off, then as 4th digit of key is pressed the led turns back on
5. release component key-->led turns off, try using your remote, if it doesn't have all of the functions you need, try a different code
6. if the led blinks 4 times after entering code you have entered an invalid code, try again.

MANUAL SEARCH AND ENTRY:
1. turn on device
2. hold the component button--> led lights up and stays lit
3. while holding component button hold power button-> led turns off then turns back on after 3 seconds
4. release both buttons--> led stays lit
5. push the power button a bunch of times until the device shuts off-> each time the power button is pressed a different code is sent to the device, the led blinks each time.
6. if the device turns off press the stop button to save your config.
7. if the led blinks 4 times you have reached the end of the code list, there are hundreds of codes, you may be pressing the power button for a while...

AUTO CODE SEARCH AND ENTRY:
1. repeat steps 1-4 of "manual search and entry"
2. press the "play" button--> led blinks 10 times, sending a code each time
3. continue pressing the play button until the device turns off
4. if the device turns off press the reverse key to until it turns back on then press the stop key to save config.
5. if the led blinks 4 times you have run out of codes, try a different method.
Now if someone would please post the codes, or if someone knows the code for a durabrand DVD-1002...

Kv24fs120 dead set with two led blinks


Two-blinks of the "Diagnostic STANDBY/TIMER LED" indicates one of two things:

1) Horizontal Output (Q502) in shorted on the A-board.

or

2) IC702 is shorted (CB board)

Two-blinks of the diagnostic red LED is a " B+ Overcurrent" problem.
The red LED will blink 2-times, stay off for 3 seconds, then blink 2-times. The cycle repeats.

The circuit board is quite delicate. One should not attempt repairs (unless one has high quality vacuum desoldering equipment such as a PACE desoldering unit).

Blinks twice pause blinks 4 times


SYMPTOMS
Dead or Shutdown symptoms.
RESOLUTION
Dead symptom reported to be caused by the following:
1. Dead.
Found Q601 & Q602 shorted, R615 open, and IC600 on the A Board were the cause of the symptom.

2. Dead.
Found D614, Zener diode, on B+ line was shorted.

3. Set shutdown and the standby LED blinks 3 then 5 times.
Found 200v line was low. Disconnected CN706 on the C Board and found 200v now
present on CN706/pin 7.
Found: IC702 (C board) shorted the 200 volt line.
HQ Comments: C541 on the A Board could become defective if the 200v line is shorted since
the polarity on the capacitor will become reversed. R553 fuse resistor could also be opened
on the A Board.

4. Error code of 4 blinks .
Dead set press power button you hear the relay and you see red led flash 3 times and stops? Has no HV or other action. Tech removed the back as no 200 volt supply, did unplug CN706 and now has 200volts. Tech did remove the IC702 and same it comes up so needs this IC.

of the transistor causing an intermittent connection.
Soldered the collector of Q606 and set returned to operation.
HQ Comments: Also refer to E30968554.

8. Dead. 5 blinks or 3 blinks
Found on the A Board D611 in the Power Supply open, and Hor. Output Q502 shorted.
