Hi Sandy, the problem with your TV is called "convergence". It can be a problem with the convergence board or more likely in this model in the power supply or deflection circuits. Unfortunately, troubleshooting by a technician is required.

you have a shorted resistor in your power supply section feeding your board check the schematic and, reduce the too-high voltage in one or, more wires at the deflection board by placing the appropriate resistor(s) in the offending wire(s.)

You need to replace your STK392-150 I.C.'s, Also, check all of the large nearby resistors, make sure none are burned, and remember, you have to check the resistance out of circuit with a meter.

once the resistors are checked, and the convergence I.C.'s replaced, you should be able to converge the picture through the user menu.

Resistor identification


Hi fccjben;

The color code is as follows: blk = 0; brn =1; red = 2; orange = 3; yellow = 4; Green = 5: blue = 6; violet=7; Grey = 8; white = 9

Unfortunately, if it is wirewound, they usually printed the resistor value on the body of the resistor. For sure it shouldn't be glowing. Sorry I can't be more help, but without a schematid, can't do much else

Good luck Loringh

Power problem (switches to standby)


its the problem of the ics on the main power supply board

Do the IC heat sinks get warm??

If they do not, check fuses F852 - 2AMP, F853 - 1.25AMP, F850 & F851 - ALL 5AMP on the power deflection pcb. THESE ARE NOT GLASS FUSES. They are usually about the size of a 1 watt resistor and either green or orange in color. They are soldered in. The nomenclature is printed on the component side of the board. They are all about centered on the opposite edge of the PCB as the high voltage transformer.

If you have cleaned up the mess you describe you most likely have one of these fuses blown.


if dont have any technical knowledge its advisable to call a technician as it is worth getting it fixed.

thanks.

Zenith IQC50H94W will not power up


First off, check Q655,EP98,and D756. If they all check good it may take a service manual to troubleshoot this set which is based on the Hitachi DP-05 chassis and is similar to their model 53FDX01B.
