You could try contacting the repair shop via the info I previously posted if you need more info.
My comment was not really meant towards you since you did try to post something helpful.

I did call that place you listed twice, left two messages, never got a call back. Local shops are not necessarily going to work with out of state customers. If you read up you'd see that I posted other repair shop info for So Cal folks. I also posted info so anyone in any state can have their local Sharp authorized repair center get the correct info from Sharp.

Talking How to repair the sharp elite pro60 pro70 ir board if it stops working

UPDATE!!! This WORKS!!!! Fixed the PRO70 IR board today by replacing the two bad capacitors per the info I previously posted above - well actually only one capacitor was bad but I replaced both since they are next to each other. one of the caps was shorted internally- see the links below with basic info on how to use a simple multimeter to test for a faulty smd capacitor.

With the right solder iron (inexpensive hot air smd rework station) and low temp solder paste, fine tweezers and magnifying headset glasses, I had the board repaired in 15 minutes. it's not hard and I am not an electronics expert.

SEE PICS FOR CAPACITOR LOCATIONS! REPLACE THESE TWO SMALL CERAMIC CAPS (PARTS INFO IN MY PREVIOUS POST ABOVE).
SHARP WILL NOT TELL YOU THIS INFO- THEY ARE COMPLETE JERKS! AND ANY SHARP REPAIR CENTER WILL CHARGE YOU AT LEAST $200 FOR A "IR BOARD REPAIR KIT".

Also you do not need to take the entire panel off the back of TV. you can sneak the lower corner open and wedge it so you can remove or install the IR board. the board clips into place (clip is on inside / left side of board, move that to side then pull rearward on the left / inner side) and it has one small plug. see pics

If you feel more comfortable, pull the rear cover of TV to remove the IR board, reinstall the rear cover, then just sneak the corner open again later to reinstall the board.

PICS!!






How to test for shorted capacitor with ohm meter:
or

TIP: Use the metal case of the ir emitter on the board as the ground for one of the meter probes

TIP: Buy some low temp solder paste and a hot air smd rework station from amazon,
https://www.amazon.com/Tek-Motion-Di.../dp/B01MR2IWBN
https://www.amazon.com/Clean-Tempera...dp/B017RSGPI8/

or, use a low temp fine tip solder iron about 300f.
For the hot air rework device you'll use 300f and air setting 4.
If you use a regular large solder iron it will crack the ceramic smd caps from too much heat.
