VP50HDTV10A YSUS Board Help

[ncwookie]

First time poster, long time reader, and may I say I have learned a bit from you all.
But now I have an issue that I am unable to find the answer to on here so here we go.I am getting open result on R54 and R55, What are the replacement specifications for these resistors/fuses?

Thanks in advance

I believe they are 5 Ohm 5W x2. Check your IPM module. Its probably shorted.

How would I check that if those are open. Please advise

Voltmeter on Ohm setting black lead on ground red lead on every Other pin on the IPM module besides ground if you have a short it will show up. of course there are two modules you need to check both

OK here is what I did and what I got. Grounded to mounting hole and verified by touching grnd pins. Tested on each side of both IPM's all open no shorts. But In the picture attached hopefully you can see the red circle around 5 pins those sounded off like the grnd next to them is that correct? Are my IPM's ok and I just need to replace the fuses?

I just replaced resistors on R54 and R55 on the Y-sustain of the same TV. If the colored bands are brown, black, black, gold it is a 2watt 10 ohm 5% tolerance flame proof resistor.
I purchased From digi-key part #RSMF2JT10R0CT-ND
R265 was blown on my board as well.
