If you check the 15v pin on the board You probably will find the 15v shorted to about 5ohms and one of the two large units on the board is shorted 4921QP1002B. I myself am looking for that part. If you bought a new board can I get Your board for parts?

Why does my TV turn on then off when i turn it on either by the remote control or the power button on the TV?


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

LG Plasma 42pc3d turns on, pops, then turns off


The first thing you should look into is the Z-SUS board, the one situated on the right side viewed from the rear. This board develops a high voltage during operation that might be the source of the popping sound. It is also responsible in refreshing the panel for proper picture display. The weird colors on your TV indicates a faulty Z-SUS board.
Note: Unplug the TV and wait for at least five minutes in order to allow the voltages to drain before you disconnect or reconnect any connector.

  • Disconnect the Z-SUS board from the Y-SUS board. The Z-SUS board is situated on the right side viewed from the rear of the TV while the Y-SUS is on the left.
  • Plug the TV back and turn it on.
  • You will still be able to see the weird colors the moment the TV shut off but do not flash. If it does not pop and stays on and there's a sound, you are pretty sure the Z-SUS board is faulty. Replace it.
  • If it still pops and shuts off, disconnect the Y-SUS board from the power supply. The Y-SUS board also develops a high voltage during operation. The power supply is the one right between the Z and Y-SUS boards.
  • Re-apply AC power then turn the TV on.
  • You'll not be able to see any color or video. If it does not pop and stays on with sound, you have a faulty Y-SUS board, replace it.
  • If it still pops and shuts off, please let me know.
Feel free to update me of the result and your own findings.

No picture on my Toshiba 42HP66 plasma tv.


I too have this problem with no help from hh Gregg, where I bought the tv, and no help from Toshiba. I resorted to calling the BBB and complaining about the defective workmanship. I took the tv, which is less than 2 years old, apart and found the y-sus board, behind the y-sus board is a foam rubber spacer to seperate the circut board from the backside of the screen. I think this pad is designed to prevent heat buildup in the y-sus board. The pad itself is held on by glue and that glue melted causing the y-sus board to short out. I noticed this after finding a tacky substance behind the board. The heat from the plasma screen melted this and also the pad itself. Toshiba claims no resposibility because the tv was out of warranty. Thanks Toshiba.

Haier tv video problems


Hello,

First of all you have to find out whether this unit has been upgraded with a new software or not?
If this unit is upgraded with new software either you have problem in Y-sus board or Z-sus board.

If this unit is having problem for the first time I would recommend to Change the Service Kit
Part number is TV-3940-01.
This kit contains E-prom,Y-sus board, Z-sus board and Control board you have to change these 3 boards together with E-prom IC.


Dont Forget to Rate!

Good Luck

Plasma tv picture went black


I would say you dont need to repalce Servcie kit.kit is only for 42EP24S units.
examine your unit What is the problem?Is the blue indicator on?If indicator on you will have audio.
In this case I would check first Y-sus board or Z-sus board.

Good luck

Philips 42" plasma model pf5521d


The Z sustain module blew it's transistors. It may have been initiated by the Y sustain board going bad. I always replace both at the same time so as not to waste $250. You will find a Y sus board will run you between $250 to $350 and a Z sus is a little cheaper. I wouldn't replace one without the other. Let me know if this helps.

Sony FWD-42PV1 -


I diagnosed the same problem on my FWD-42pv1 as a problem on the Y-SUS board. The fuse on that board was blown, and the board itself was bad (replacing the fuse was not enough to fix it). The symptoms were exactly the same - the LED cycling red/green, and then finally stuck at red.

With a new Y-SUS board, the TV has been working fine for a couple months.

My LG Plasma TV RU42PX10C


Hi all..i had the same problem with my 42 inch LG
rz42px11. its a faulty zsus board(Z sustain part no 6871QZH033A) the pop
sound was the fuse on the board blowing.not that hard to replace but be careful with the connector ribbons! got my replacement from
https://www.chsinteractive.co.uk/ £150....expensive,but probably cheaper than
calling someone out to fix it.
P.S i tried just to replace the fuse on the board T2AH 250v but it blew,i think the fact the fuse blows means the board is faulty..but you could try.
hope this helps someone.
Good Luck
