You Said that you unpluged white wire coming from flyback transfomer going to Where ? if this wire goes to your screen and focus block control, and set comes on then your screen/focus block is bad also if it goes to the high voltage spiltter block set will set down . How to tell disconnected Red lead ,high voltage lead comming from FBT,if high voltage comes up the trippler/splitter block is bad.

First try that IC then report back. Unfortunately this is the process to fixing the tv. Once you have done that I would love to know the results. If you need assistance before or during that time please let us know. If you have a moment please accept and rate a solution you find helpful and I'm sure the expert including myself will be more then happy to assist you further if need be.
Thanks

Now that you've gone this far, youcan continue with this:
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.

If this is too much for you then call an authorized service center to repair your 2001 Model TV and have them give you an estimate.

Test the power board first.

    Sorry,

    23 means Horizontal Deflection failure, therefore you will have to check a number of component failures that can cause horizontal deflection failure, following the service manual/
    The most common problem is the failure of vertical output amplifier, that cost around $150 to have repaired.
