Power shuts off 1 second after tv is turned on
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 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.
I hope this was helpful, BIG IRISH.
The TV turns off without warning. Sometimes after being on a long time then again if only on for about 30 minutes. I have pressed the on button and input -but no results. I have unpluged the set for lengthy times, replug and it may come on or not. Sometimes I have to leave it off 24 hours. The green timer light on the front of the TV will flash twice but nothing happens, no codes, etc. Then it may not be a problem for a whole week then the next several days I cannot get it on. What now?
T.V shuts off and does not come back on for awhile. Then will last a little longer.
after being on for a while 3 or 4 hours i get yellow blinking lights and my tv shuts off I can turn it right back on but it does it again in about 15 minutes. whats happening? Its only 6 months old
tv shuts off and repair man says it need some kind of board and which they don't make anymore
Same prob, TV has a mind of its own, shuts off erratically, sometimes not for several days, then several times in one day. This set is usually on at least 12 hours a day.
