The power supply is what is causing it to shutdown, and if you replace the bad electrolytic caps, or the power supply it will fix the problem.

Samsung le23r86wd wont turn on after capacitor changed


Did you change all the capacitors on the power supply section? There are usually 4 or 5 caps that are used in this section.

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.
