TV Repair Questions? Ask a TV Technician
Thank you for posting your question on Just Answer! I will be happy to help you with this problem. Can you please give us some more information so I can better answer your questions.
-Did the fuse blow again the second time?
-Did you replace the fuse with the same amp rated fuse?
-Can you also please double check that model number?
Please give me this information and I will be happy to assist you further.
1.) The new fuse blew immediately on power up along with the loud crack like a hard hand clap;
2.) The new fuse was an exact replacement;
3.) The model number take right from the set back( I have it off) is 42H66.
I am really sorry, but the model number is XXXXX The P is sort of obliterated, but I found the number in another place on the TV.
The TV was assembled in Thailand.
Again, sorry for the screwup.
Thats more like it :) thanks for getting that I was going nuts trying to locate technician information for you.
Ok, I need to know what the location of the fuse is? (on the circuit board there should be a number printed near it, I need that number)
Also what board is the fuse on?
Facing the rear, on the left side about 2/3 up from the bottom on the right edge of the circuit board, there are 2 fuses mounted(vertically, that is longways is up and down) next to each other. The left one is the one blowing.There is a white paper label on the bottom edge of the board. It says:
can you send me a picture of the board?
(if you can post a picture, please click the icon above where you are typing with the green tree on it. This will allow you to upload a picture)
if not thats ok, I can answer your question just want to be 100% sure so I don't give you bad information.
Ok sounds good.
Let me know!
On the far right of this picture you can see the 2 fuses side by side. The left one blows. On the far left is a tall narrow board plugged into this one. It has many LSI's on it ( about 7 I think). See the next picture.
ok, unplug the narrow board (this is called a y buffer and some manufactures call them a scan driver) Unplug the board, replace the fuse and turn it on again. Does the fuse blow?
The fuse did not blow with the board unplugged.
did the set come on?
Do you know how to use a meter? if so i need you to check the voltage at the fuse
Will it be DC or AC volts?
dc, use the back of the panel as ground, any of the metal will work
thats 200v on the fuse that is blowing right?
You need to replace that y-sus board, the part number is XXXXX
http://www.encompassparts.com/ is the best place to buy these at in my opinion, but you can choose anywhere you like.

that should be the part you need.
Let me know if it doesnt work.
I am signing off for the night but thought I would send you a quick note first....
You made sure you have all of the wires plugged in correctly right?
Made sure you hooked up that tall an skinny board correctly?
just double check everything, this should have been cut and dry...
I will be back tomorrow if you have any more questions.
Well I guess there is the possibility that when the y-sus went bad it damaged other boards along with it, but considering ordering more parts means more money and no way to accurately diagnose it any further then I would say your previous statement about tossing it might be the best way to do? Sorry about your bad luck..
Please let me know if there is anything else I can do for you!
Thanks, XXXXX XXXXX good day!
