I just picked this tv up today 50 dollars. In the power supply the two caps are swollen like my p50s601. One of the driver chips on the lower sdr board is burnt. If i unhook the sdr board then the tv powers up with the top half working. I am going to replace the two caps in the power supply and look into ordering the lower sdr board. in my p50s601 It was the top sdr that was bad now this one its the lower one. everything looks the same as the p50s601.

If you have this model check out my other tread with info about this model. http://www.hometheatershack.com/forums/hitachi/30302-p50s601-blue-power-light-flashing-3-times.html

Looks like the title has an H in it now. Did you figure it out?

Thanks for posting your experience with this set.

Yeah I forgot it. Sonnie fixed it for me. He told me i could of fixed it myself two within 30 mins after posting if i click edit then click Go Advanced. I had no idea. Basicly this set had the same issue as my P50S601 that one had bad chips on the upper sdr board. This one has a bad chick on the lower SDR board. They both had swollen caps in the power supply. The same two caps. I will take photos and upload later.

I found a guy that says he repairs these boards. When I get mine back I will let you guys know If he does a good job repairing the SDR boards. From what he says the price will be about half of what the boards cost new.

I took a video of uploaded on youtube. The caps in the video don't look swollen but they are in real life. they are slightly swollen and starting to get puffy on top. I will be replacing them before installing the repaired SDR board.


The board on the right is X-SUS and the board on the left as your looking at the back is the Y-SUS. The top driver board is the SDR-U board and the bottom board is the SDR-D. I could of done a better job on the youtube video but I didn't feel like retaking it. I am just not good on video.

I sent my board in for repair. He just contacted me saying it was done, and it will be shipped to me shortly. I will give you guys an update on how well he did the repair. I had a burnt driver chip. You could see were it was burnt. Here is his contact info if anyone is looking for someone to repair a driver board.

I found him on ebay. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=160531121035&ssPageName=STRK:MEWAX:IT

I paid for it off of ebay since I sent him an extra board i didnt need back. I had the old board from the p50s601 that i didn't need so he told me it would be less money since i am giving him the extra board, and he said just to send him a check or money order.

While there are many reputable dealers on ebay, I would be very wary of having someone do this level of work without some othert info about their qualifications and performance.

He was the only one I found that was offering to repair the boards. I looked at his feedback rateing and everyone was happy with the work. If you buy a replacement board other places there is no core charge. If he truely did ship it to me. I hope he shipped it with insurance. When I shipped him the boards I paid for enough insurance that i could replace the board with a new or a use board if one was found.

He may do great work. The point is that you don't know. How much of his good rating comes from these repairs on this board, and how many from selling shoes? There are reasons that no one repairs these. The failure rates on repairs like this are likely going to be very high for a number of reasons.

We see people all the time that get burned by ebay sellers trying to gain market share getting into things they really can't handle, or selling parts that they think are fine. It happens all the time with lamps and boards.

I hope this guy turns out to be good. There is a need for the service and we would love to be able to point people to a solution. Until more info is avaialble, however, we must remain skeptical.

I was looking at the feedback from these boards. Ebay feedback system tells you what people bought. Most of his feedback is from selling the repair service for the board. I just don't like the fact that I called him and never received a call back. I emailed him thru the ebay system without a reply to my question. So far with his communication I would say stay away. I know it may not be his fault if the post office lost the package, but he should be shipping them with insurance or delivery confirmation. I just would like to know if there is any way I can track it to try to find out were it's at or if the post office lost it.

Here is a copy of the repairs for this board from the first page of his feedback that you see on ebay.

I just received the board in todays mail. He didn't mail it out when he said he was. It wasn't shipped out until the 14th and today is the 17th. He told me last week it was mailed. It looks like he does good solder work. He put some kind of clear stuff around the chip over the pins so it doesn't have the gray stuff around the chip on that one. I am not sure if the stuff he used is made for what he used it for or if it should be thicker. He made it very thin.

I hooked it up and it works. He replaced it with the same kind of chip that was burnt. I took a video with my cell phone that i will upload the video to youtube and update this post! I need to turn the color down a little bit in the menu. I think the people I bought it from had it turned up to high. way to much color.

since its working I need help taking it up stairs to my bedroom. I will be replacing my samsung hlr5067w in my bedroom with this one. Now i dont know what to do with the samsung. It has a digital board from samsung parts in that tv that has a sticker on it saying it was modified or something. I am thinking I maybe better off to part out that samsung tv then selling it hole. I am sure all the parts are working it the tv but I am not sure how much life is left in the color wheel and all. I'm not having any issues but things to do wear out. I am thinking if i go to sell the tv i will be lucky to get 300 out of it and i can get around 200 out of the digital board and then sell the light engine and other parts and make more money off it. The same way with this Hitachi plasma. I could get more parting it out then selling it hole. But I am planning on keeping it and using it for the time being.

Good news it's been a month with no issues. :) That guy must know what he is doing with those SDR boards.


I also wanted to add an updated to this. It looks like Hitachi 50PD9800 also has the same issue with the two caps on the power supply going bad and burning out one or both of the sdr boards.

http://www.hometheatershack.com/forums/hitachi/44286-black-horizontal-lines-hitachi-50pd9800.html

p50s601 p50h401 and p50pd9800 all had the same ND60200-0047 on the sdr-u board. The p50pd9800 is almost the same as the others.

This guy had issues with black bars on the video that is caused by the ribbon cables on the sdr boards not being right. I had the same issues with mine. I kept turning it off and back on doing one cable at a time until i found what one was making it happen.


after looking at the pdf files i have listed it looks like P42H401, P42H4011, P50H401, P50H4011, P55H4011 and P55H401 and P42T501,
P50S601, P50V701, P50X901, P50T501, P55H401, P55T501 and P60X901 Plasma Televisions. May have the same issues.

Hi Jason, I had a quick question for you but it seems I cannot PM you because I am a new member ( or maybe you have this feature turned off) I had a question about my Hitachi p50s601. Is there a way to check what board is out...When I try and turn it on..it blinks twice, pauses, then blinks 3 times repeatedly.

Thanks in advance!

ok here is the service manual for the p50h401 it may also work with the p50s601 since many of the boards are the same.

You can test the sdr boards with a multi meter. one of the links i have posted tells you how to test them for resistance. if they are shorted out they will max out. They should show like 500 to 700 ohm if good. some of them you have to test backwards because they show no resistance. Also double check the power supply for those two capsitors that get swollen. They are the ones that seam to go out in this model and need replaced.

Thank you for getting back to me! I am kind of new to all this TV stuff...just wondering if you could also answer how I remove the back off the tv...do I remove every single screw? I don't want to remove unnecessary ones and mess something up.

This set has a lot of screws. Every one thats in the back that goes into the back cover needs to come out. there are screws around the outside edge. also smaller screws too. You may want to take some photos so you remember were stuff goes.

Also if you never soldered before you may want to get an iron and find something else to solder. Like an old alarm clock. You can burn off the tracings if you don't know what your doing. Just remove something and put it back on.I am guessing the caps on your power supply are most likely going bad. The two i point out in my video. Most of the dead ones of these models i have seen have had this issue. You maybe able to see if one of your sdr boards are bad by looking for a burnt chip. If you dont see any burnt chips then you have to test them all.

Have you ever done anything like this before? If not you could mess it up.
