Question about Samsung HP-P4261 42 in. HDTV-Ready Plasma Television

Open Question

Samsung hpp4261 Ok, My plasma TV went out the other day. So I call BestBuy to have someone come look at it. They told me the y-main board is out. Is there anyway I can fix the board. I know which capacitor is bad. Think I could get a new one and solder it back in? Or should I just buy a new board. If a new board is the way to go, where would be a good place to buy one. Thanks for your time! Jason

The plasma display panel can be replaced part# BN96-03290A lists for $1,460.61 at Andrews Electronics. Throw in $300+ labor to do it and you be the judge.....

SOURCE: Samsung TV won't turn on- trying to fix it. A challenging problem

I had the same problem. I live in NJ and called the local authorized "service provide" listed on the Samsung website. What a joke. Quoted $350 just to show up, never showed up. So I opened my own TV. Took off the plastic back (10 screws) took off the large metal RF shield (12-14 screws) and noticed a blown component. The markings on the component were KL15L and it is apparently an NTC Thermistor. Obviously it got fried and not knowing if there was other damage I decided to set out to replace the entire Power PCB Board Assembly and not the component. There were two part numbers on the assembled board (BN97-00457E & BN94-00622E). After searching online I also found a suitable replacement number for these (BN96-04896A). I found two places who claimed to have the part or have it on order ( and After placing orders with both and having neither come through, I broadened my search and found out that the LNR409D was basically the same model as my LNR408D so I looked for its Power PCB Board Assembly part number which turned out to be BN41-00521B. Google search for that part number showed the item available on ebay. I bought it a week ago (ebay 260311519904) for $144 plus $12 shipping. I removed the bad board an hour ago (6 screws about 7 connectors) installed the new one, plugged in the connectors, replaced the covers, plugged in the TV... AND IT WORKS!
Suggestion: If your TV is out of warranty then open it up (what have you got to lose) and see if the problem is obvious and maybe something you can fix (replace) yourself. The parts, spare boards, etc. are out there if you look.

SOURCE: Samsung model LNT5271f excessive relay cycling before full power

Yes, it is very easy to repair. Solder iron wattage should be at least 300 w.

The PSB is the center Board (towards left) after you remove the back off the TV. Remove the shield that covers the Boards and remove Board from TV with the 6-7 screws. Replace capacitors CM852 & CM853; 2200ufd 25volts.

Good Luck, big IRISH.

SOURCE: Which Replacement Power Board for LNT4665F Samsung LCD TV?

It would be a lot cheaper if you just replace the two caps that have gone bad. Just get a cheap solder pencil from the store and about an inch of solder and you are in business.

To all who are having power supply issues: Samsung is now acknowledging a problem with faulty capacitors. I called 1 800 726-7864 and they said they would repair certain out-of-warranty TVs if the problem is related to the capacitors. I just called and they are sending a service rep out to diagnose the problem.

Take a DMM put it in resistance mode to measure upto 1K Ohms and check the resistance across C5515, C5502, C5504, C5507 (LOW BOARD), Then check C5415, C5402, C5411, C5404 (UP BOARD). The defective board is the one that will have around 100 ohms or less across these capacitors.

42" Sanyo HD Plasma TV (Model DP42746)

Not at all crazy! The Samsung/Akai lines seem to have numerous problems with their Y and Z sustain boards and upper/lower Y driver boards (aka buffers). That and power supplies are generally the largest percentage of the problems in those units. That said, I'm a bit confused looking at the p/n you referenced. I don't see that as being a Samsung number belonging to a Y-sus board. Usually they start with BPxx-xxxxxx..
Lastly, while you might have every ability to replace the Y-sus board if the buffers are bad and you don't replace them you could simply burn up the sustain board when you power it up... Installing the buffers is a bit more complex than the sustain board so be really careful there...\
Good Luck

Remove the power supply cable to Y Main board, check Vs on power supply board when you turn on tv.
1. If you have normal Vs, replace the Y Main board. If still not work, replace the Logic board.
2. If you don't have normal Vs when you try to turn on your tv, just replace the Power Supply board.

Blackout problems

It could be the LVDS cable that is connected between the logic main board and the main board, sometimes this cable is too short and comes loose from one of the boards, it could also be a sign that the logic main is going out or the panel itself is shorting out
