To restore your television you will need to replace the eeprom. Let me tell you why! The stereo decoder and signal processor at one time were confused with the microprocessor. This corrupted the eeprom. Without the following information, repair is next to impossible. Fortunately the repair is near..so pay attention! Location of the eeprom is IC002 on the TV board. You will need to know the numbers on the IC 001 (the microprocessor) and the numbers on IC1001 (stereo decoder). This will determine which correct eeprom to replace. The reason I say this, is there are six different eeproms to choose from. Show this info to a TV tech if you cannot do this yourself. Thanks for asking and show a few a few hands of support.

During a storm, i had the tv on & the picture went out on it when it thundered.


Sounds like an overlaod in the power supply. Check the cap at C835 and if possible use a cap-analyser on all of them in the PS circuit. Are there any signs of life when you press the power button?

Try unplugging the set from the AC socket, letting it sit for about 20 seconds, then plugging it back in. This allows the computer inside to reset. If that doesn't help, then it's time to have the set serviced.

Tv will not turn on


A: Is there a humming sound coming from the TV set?
Check the brightness/contrast. If nothing still, remove power to the set for 24 hrs. and reconnect and retry. If it's not coming back up, the PCB ("motherboard") for the set has most likely died. Check for warranty information in your user's manual for further instructions.

B: Is the TV sharing an electrical line with a wall switch?
Remove the set from that circuit and try another outlet. If not, follow the Steps for "A".

C: Was it during a power storm, when it went blank?
Check the outlet with another appliance - if that device works, try the Steps in "A".
