If you have become discouraged about your dim display in this now obsolete VNA, or you are tired of that clunky ol' VGA monitor hanging off the rear port, I have good news for you!!!

The original TFT displays for these VNA's were manufactured by Sharp Electronics. They were a customized display with a 22cm diagonal viewing area. The original Agilent p/n's were 08753-60325, 08753-60937 (among others) and was designated as A18. They fit the 8753D, 8753E, 8753ES, and 8753ET VNA's. The current Sharp p/n is LQ084V1DG22, BUT IS NOT AN COTS unit. The cost through Agilent is $1,275.00.

However, there is a Sharp display that is VERY close to the OEM part. The Sharp p/n is LQ084V1DG21 (one digit off). The last two digits refer to the diagonal viewing dimension in cm's. Well the 1 cm difference is negligible. Everything else is identical and it is a "drop-in" replacement for less than one-third off the OEM price (if it is available).

I bought mine for $400.00 from Future Electronics which stocks this part. Apparently, this display is used in a lot of instrumentation and bank machine applications, so availability is good. I did have to modify the backing plate slightly for a good fit, but it is made of plastic and can be modified with a pair of side-cuts. Availability through: ... 084V1DG21/

Absolutely everything else is compatible, including the electrical connections. I connected mine up in less than 30 minutes and the results are amazing! I would encourage anyone to make this repair and get a few more good years out of their 8753D/E/ES/ET VNA's.
