I had the same problem and fixed with a great online tutorial. Just replace 3 capacitors available at Radioshack onthe the board. 2662, 2663, 2664 1 is a 1000uf the others are 100uf. Max Volts need to be over 25. It worked great, check http://dynamicorange.com/2008/06/25/fixing-a-plasma-tv/

Samsung TV model LN32A450C1DXZA, after turning the TV on it will turn itself off shortly after and then turn itself back on shortly thereafter. Then it repeats that several times before staying on.


Hi there,

If the tv is still under warranty, this can be repaired at no charge.

However, if not under warranty, you will need to have the CAPACITORS on the main power supply circuit board tested (or replaced).

The capacitors responsible for the power supply can sometimes fail - open the back panel. If the capacitors on the main power supply board look too fat, or signs of burning near the solder joints, then you've found the problem.

Hope this helps.


Cheers,

Scott

My Aquos TV turned its self off and now it wont turn turn back on.


Turned off by itself means overheated in the circuits. If it is condensation, leave the standby on for a few weeks. Try using it to see if it will turn on for a short time.

Turn off after a few hours


If the TV turn itself off then perform the following steps:

(i) Check if the Sleep timer is activated.

(ii) Check if the Parental Guide prohibits viewing during that time and/or limits amount of viewing time per day.

(iii) Check the batteries on your remote, low battery power may cause random signals from the remote.

(iv) Disconnect all the cables from the TV then reconnect them after a few hours.

(v) Ensure the power cord from the TV is directly connected to a functional wall outlet.

(vi) You may also try resetting the TV to the original factory settings by pressing the Reset button on the remote control supplied with the TV when in Menu.

The following is the information indicated by the blinking patter of the standby/timer lamp on the TV:

2 times : Power does not come on.
Load on power line shorted.

3 times : The TV has entered standby mode.

4 times : Has entered standby state after
horizontal raster.
Vertical deflection pulse is
stopped.
Power line is shorted, or
power supply is stopped.

5 times: No raster is generated.
CRT Cathode current detection
reference pulse output is small.

6 times: No picture

9 times : No sound

Furthermore, the TV is equipped with a self-diagnosis function that you can use to determine whether the issue is related to any hardware malfunctioning. Perform the step given below to run self diagnosis:

Quickly press the remote command button in the following order from the standby state.

Display -------> Channel 5 ---------> Volume -(minus) --------> Power ON.

If the Self Diagnosis display numeral "1" for any parameters then a fault has been detected and service will be required.



wish u good luck!!!!!!!!!!

Turns on and turns off.


Good Day;

This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source) 1. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR LEAKY C9A60 470 PF 1000 V PART # 154P400030, PARALLEL TO D9A57 ON THE POWER PCB. 2. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR OPEN FUSES F9A04 AND F9A05 PART # 283P043090 ON THE +24 AND -24 VOLT LINES. IF THE FUSES ARE OPEN THE CONVERGENCE OUTPUT CIRCUIT WOULD BE SUSPECT. OR your TV has "COOLANT" (ethylene glycol) on the circuit boards. This fluid comes from the CRT's (picture tube) this fluid is used to keep the CRT's cool, such the name. This fluid from the CRT's leak when TV is on for long periods of time, the chamber expands and the seals leak.

One can remove this fluid by using "acetone" & small brush. The fluid is hard to see, use bright light, they spots can be smaller then a DIME. Also, the fluid can corrode the parts and traces on the boards. To protect the TV in future place heavy plastic or thick cardboard over affective area, make sure TV has proper air flow around TV. Good Luck, big IRISH.

After my 70" tv is on for a period of time, it turns off and won't come back on for a while.

Turns On then immediately turns itself off


Good Day y'all;
First I will tell you what the factory tells us then I will tell you what the problem may be: This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source) 1. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR LEAKY C9A60 470 PF 1000 V PART # 154P400030, PARALLEL TO D9A57 ON THE POWER PCB (NOT SHOWN IN THE SCHEMATIC). 2. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR OPEN FUSES F9A04 AND F9A05 PART # 283P043090 ON THE +24 AND -24 VOLT LINES. IF THE FUSES ARE OPEN THE CONVERGENCE OUTPUT CIRCUIT WOULD BE SUSPECT. 3. SELF-DIAGNOSIS INDICATES SHORT PROTECT. CHECK FOR A SHORTED IC4B01 PART # 270P261020 (VERTICAL OUTPUT) LOADING 24-VOLT SUPPLY LINE. LOCATED ON THE MAIN PCB. This model is also known to get fluid on the boards. The fluids come the picture tubes, this helps projection TV's to keep cooler tubes, all companies use this method, but MIT has the biggest concern of the leakage.
Sorry, but hope this was helpful. These TV's can repaired, shields can be provided. Call an authorized service dealer to this repair.
Good Luck, big IRISH.

Mitsubishi VS-50707 shuts down sporadically


you can do a self-diagnosis test by pressing the menu and input/device button on set for 5 sec and see what error code it gives you. Count the blinks followed by a short pause then more blinks. This is the error code.

Wont turn on


I'm not a tech but I read the self diagnostic repeats itself 5 times. That being said I think it is telling of a 2-2 problem. A result of 2-2 is a short protect problem. Hope that helps.

The flashibg red light


John, I do not know of a code, but it is a good idea in the design to have several goes at starting a circuit, before completely shutting it down. Oscillators are supposed to self start due to noise generated. Some electronic circuits require a reset pulse to be generated before the start up is allowed. The reset circuit may not be generated if the set is turned on again too soon, so it will stay in standby. This may normally be a few minutes to 30 minutes so it seems something in your set is faulty and could get worse. Try a test run with the back off and clean it out of dust with a long brush to keep it cooler. Make sure little fingers cannot get near it. Look to see if anything is obviously overheating.
