If you have audio, but no video for any inputs it is likely it is the Y SUS board.

You should still open the unit and verify that its either the YSUS, ZSUS, or control board. Check the fuses to see if any are blown. If so, it is likely that board is bad. I don't know why they built the boards to blow before the fuse does.

For my issue, I had same problem but wasnt sure what to buy. I did open it and find 1 blown fuse. I replaced it and it still didn't work(hence a blown board).

While it was open, I noticed its all LG parts inside. So, write down the numbers of the unit and the part numbers off the YSUS, ZSUS, and main logic board.

Since its possible any of the costly parts could be bad, I ended up calling Haier and getting the local support shop to take a look at it. I paid $75 for them to tell me what I already knew. They wanted another 425 to fix the problem and extra $ if they needed to tune it further. They said the part was about 370.

Since there was no guarantee that I would be paying only 500, I figured I could check around to see if I could get a cheaper price. Also a new tv runs about 600-800 with a new warranty. In the end, I ordered the part from shopjimmy.com (one of the leading replacement parts places - they sell new and used parts) for about $175 with shipping. I paid a bit more for a new Y SUS board but it was worth it. It was still cheaper than the factory price of about 275-300. Luckily, I did not have to tune anything.

I'm not affiliated with shopjimmy, but they seem to be really nice(I called twice to ask for information) and have a good return policy. They are also cheaper than the other online parts places. SHOP JIMMY also lists on ebay, so you can find them there too. If you go to their website, you can find your brand and tv model and see what parts they have. They also give part numbers. They DO NOT have CROSS REFERENCE INFORMATION. However, the same part numbers are listed under other TVs and models. Remember LG is the manufacturer and the other companies buy from them. They only change the skin and the look of the tv for their own needs. I'm not sure what you mean by hybrid, but the parts that are interchangeable from model to model are really the same parts with different part numbers.

Another way, to search shopjimmy.com is to use the part numbers you pulled off your tv. This will identify all brands that use that exact part. Again, shopjimmy will not verify the parts will work in your tv. They only tell you to compare your part with the picture they show.

Once you get the part number off your TV, you can also google the part and see what comes back. I read alot about different issues. This is also how I found out that other parts from other brands will work in my tv....but the postings did not guarantee it. Try googling "Haier 42hp25bat parts" and "(the part number) LG parts".

The part I got was for a MAXENT. It was LG but for a MAXENT. I verified the part looked exactly like mine. Remember to look at circuits too. I noticed a few of the same boards had slightly different capacitors AND did not know if they would negatively affect my TV.

My Haier is now working fine. I snoozed on it for 8 months before fixing, but at least its up and running for superbowl weekend!

Bottomline, if you want to take a chance buy the Y SUS. As costly as the parts are, there is no guarantee that only one part is bad.

Also, the repair shop said to get warranty cause they see alot of issues with no name brands and the less expensive units. They said the brands they dont see many issues with are the old school brands, like Sony, Toshiba, etc. I have another TV that I just got a warranty for just before it expired....it was $300, but at least its covered for another 4 years.

GOOD LUCK.

Our Haier 42HP25BAT Plasma TV made a loud pop sound and the picture went out but it has sound...will the replacement of the TV-5210-96 Digital Board solve the problem?


The TV need a thorugh check up, before doing any repair to it. Some repair works, can be done manually. It sounds that some electrolytic capacitor on the main power reguaator board has bursted out. Check the power regulator baord first. Digital baord faults are rare. In most cases, main power board might be replaced as card basis.

I have a Haier 42HP25BAT With sound and no picture ??


Hello,

Problem is in either power supply or the Y-Sustain board.

The Y-Sustain is a relatively large board out of which go connections to the side of the display; it's therefore closer to either the left or the right side of the display, has at least one rather large heat sink on it and fat power cables connecting it to the main power supply.

Often there are fuses on that board - one or more. Check those.

if they are blown you can try to replace them, but expect them to blow again - usually the whole board needs to be replaced.


I hope this help in solving the problem....

Some troubleshooting help please.


The part that caused the fuse to blow is the hybrid that is mounted underneath the heatsink on the YSUS and ZSUS boards. The part used on these boards might be YPPD-J017C or YPPD-J018C, in about 90% of the time, replacing these hybrids fixes the plasmas with no video but good audio. Since VS and GND is shorted, that means that the hybrid has shorted internally. Most service techs would rather replace the entire YSUS or ZSUS boards since the hybrids are very difficult to remove.
Let me know if you require further assistance.

Black Screen with Audio


Sears knows of this problem - the key is to convince them to come out and replace the three circuit boards for free - argue that they should have recalled or fix the MONITORS proactively and that this isn't the service level that Sears is known for. Mine was out of warranty, but they still came out and ordered the boards. Also, make sure when you buy a new Plasma, that you buy a Television, not a Monitor to avoid the frustations about tuners.

You can order the parts and plug them in yourself. I did this, since it takes weeks to get the Sears guy to come back and do it. It was simple, but isn't recommended unless you can't wait to have your tv back. Sears sends parts by mail directly to your home...

It looks like the Ysus board failed on your TV. I just fixed one of these TVs by replacing a hybrid that is found on the Ysus assembly.
You can also buy the whole assembly from this site.
Good Luck.

Harish.......If you've lost both audio and video you'll probably need the upgrade kit. If it were just video you could get by for sometime with replacing the slow blow fuse on the s-zus board. Check your eprom chip on the digiatal board to see if it appears burnt. If so it may have fried. If you'd like the service manual I'll need your email address

Black screen w/sound


My Haier 42EP24S did the same thing 23 days after the warranty expired. I am an Electronic Technician by trade so tried to repair it. I found that the problems was on the YSUS board. The Vs supply line develops a short and causes the 4Amp fuse to open. This is a common problem with this LG made monitor. There are no board level schematics available for this monitor so component level repairs are almost impossible, board replacement only. The YSUS board cost $460 from haier. I complained to Haier America and they replaced my unit with a new HDTV. That was 6 months ago and now the replacement tv is going junk. Good Luck.....

There is a easy fix - Most of you purchased your television at Sears or BrandsSmart Stores - No picture but you can hear sound - the part you need is the upgrade kit - part: TV-3940-01 - the part is not always available.
