?Attention, SD TECH? Convergence problem: Panasonic projection TV, PT-53WX53G, chassis AP825, Serial LX 31970463. I've seen your other answers and ask if you could please send me instructions for replacing IC? Also, do you know where I could download service manual? Thank you. Unemployed and picked up to fix and replace small CRT. Eric

Try vance baldwin, they have good prices and will sell to non service shops. Hope this helps

Hi,
IC451 (Vertical Output) LA78045 part number is C1AA00000521
Available in Part Store.

Thats the error for convergence failure. Heres a link to the repair kit for your model which contains the parts and the CD with detailed instructions.

SOURCE: tv still turning off blinking three times after hori ic replaced

Three blinks is short protection.

97% of the time it means one or more of the 2.2 ohm blue resistors around the two convergence IC's is OPEN.

There should be 8 or 10 of them: light blue in color and will have 2.2 printed on them ------look for any that are slightly discolored or white in the middle.

What happens here is if one opens====one of the two convergence chips got it----they can be tested in place like testing a fuse===no reading across any of them and it is gone-----set detects no voltage reaching the chips(Usually STK-392-110---black in color and on metal heat sinks with fins side by side.)

DO NOT JUST REPLACE THE RESISTOR IF YOU FIND ONE BAD=ONE OF THE CHIPS GOT IT.

I have start to finish, step by step instructions showing what is needed and the best way to replace the chips etc.

FIRST: LOOK TO SEE IF any OF THE RESISTORS ARE GONE. (BAD)

If you want the instructions let me know and I will post them here for you.

Regards, SD TECH


FYI= Whoever told you to replace the output transistor does clearly not know these sets very well as it will produce a 5 blink error code.

Testimonial: "I already replaced all of the resistors with new ones. I have new convergence ic's. Still comes on for 2 seconds then shuts off.Any other suggestions?"

SOURCE: PT-53WX53G still shutting off-3 blinks

have you checked the 2.2 ohm 2watt resistors? If the led blinks three times the resistors will almost always have at least one that will be blown and need replacement.
