PT51HX41E PANASONIC picture comes on the after 5sec or co turns white.

convergence failure. You can get the repair kit for your model which contains the parts and the CD with instructions at the following link. http://servicemanuals.vstore.ca/product_info.php/pName/panasonic-projection-tv-convergence-repair-kit-1/cName/convergence-repair-kits

Says bad 15V bad. To check on D board.

Clean the projection lenses with qtips and alcohol. Then try to use the convergence function. My blu was messed up on one side of the screen until I cleaned mine.

two STK392-110 Convergence ICs and also check the six 2.2 ohm 2watt resistors.

your model has two STK392-110 CONvergence Cs, you will also most likely need at least a few of the 2.2 ohm 2watt convergence resistors. I am posting a link to the actualrepair kit for your model which contains both Convergence ICs and all 6 of the convergence resistors and they send instructions with pictures that show how to do the repair.

Your service manual on page 82 steps you through decoding the blinking
1) there are two lights on the front near the reciever of the remote signals (Temp indicator and Lamp Indicator)
2) If the Temp indicator is on then they recommend you contact a service center
3) If the Lamp indicator is on and the power light stays on (no blinking) then you need to replace the lamp. Otherwise it says to contact the service center.
4) Counting blinks with the lamp indicator (1 every 5sec - lamp will not light or is abnormal, 2 every 5sec - lamp voltage is abnormal, 3 every 5sec - lamp temp is too high, 4 every 5sec - other error)

Bill

the covergence ic;s are faulty

you probly wont have to replace any resistors ,use STK392-180s.

Hello, please check the IC7102 (24LC64). This is eeprom that contains the convergence data. Please ask the Panasonic dealer if they can supply a replacement IC with the data for your HD. If you need more info please advice. Arpi
