    RESOLUTION
    Checked the 9, 30 and 5 volt lines all check good. Check ohms from AFT out on tuner to
    CN100/pin 30.
    Re-soldered R087 on the A Board corrected the auto tuning feature.

My Tv started with flashing red/orange colors. Then later the screen turned red/orange and the TV shut off. When I attempt to turn it on again, the screen stayes red for a few minutes then shuts off.


The problem based on the model number is in or around the red picture tube---the bright red screen causes the set to draw too much current and the shutdown circuit detects this and turns set off--self protection.

Each picture tube (3) has a IC chip on the board connected to it--shorted chip or bad picture tube.

Shop repair in most cases.

I have an RCA HD52W59 TV that will turn on and picture is fine for awhile, then it will fade to total black. Still has sound and does not power off. Nothing will show on screen, not even menu options....


Thats a deflection problem which is causing the CRTs to shut down during deflection loss. The deflection board will need replacement. You can get replacement deflection boards from www.tvrepairworld.com

Sony Trinitron screen flashing


The picture tube is starting to fail. The increased screen voltage allows it to stabilize at the expense of color quality. Sorry to say, but it is time for a replacement.

KP-51HW40 Sony 51" Fades to blue screen


The service manual on page 8 shows how to adjust the Red/Blue/Green screen voltages. To get to the adjustment board, take the front speaker grill off (two screws at the bottom left and right) and set it aside. No need to disconnect any wires. Then remove the plywood board with 4 screws that exposes the screen/focus adjustments. The top 3 adjustments are for focus, and you need not mess with these. The bottom 3 adjustments are for Red/Blue/Green screen voltage rough adjustments. My screen showed red lines, so I had to turn the bottom right adjustment with a philips head screwdriver just slightly until the red gun retrace lines where no longer visible.

Good Day, checho3435;

Look for fluid on the PCB's or check these items:

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/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). Good Luck, big IRISH>

Picture fades to black then reappears and repeats fades to black .


Is the sound ok. Yust the Picture. If both dissapear replace power supply board. That is the main big board with the most heatsinks on it. Main power gos from a switch board to main power supply.
