Re HP PL5060n

Hi there!!
Thankyou so much for the info, do you know if the Y sustain board is on the right, that is where some liquid splashed into the tv. I found the part on ebay and was wondering if I could install it. (i'm not that electronically inclined) :)

Well if you open the set maybe you can fix it because now you are telling me something that i did not know, i tell you what to do. open the tv and take a good luck at the board were the liquid got into the tv and maybe you can find a blown fuse. that will be the best thing that happened to you in case that is bad just look at the part number wich is on the board.
just let me know what you found

No screen boards found. Do you mean any of these?
Types of TV Boards Every TV uses a collection of various boards to perform every function imaginable in a television. The boards work together to produce sound and images on a television screen. When certain mechanisms in a TV fail, it might be time to start testing different boards to see if they are functioning properly.

Main Board

The main board is the central hub of a television circuit system. The easiest way to identify a main board is to find the board with the various video and audio inputs/outputs. Generally speaking, main boards also contain a tuner, HDMI, USB, and S-video port. Main boards are one of the largest boards in a television. Main boards might also be referred to as a motherboard, main module, or an A/V board.

Power Supply Board

Another large and important board inside a television is the power supply board.. Usually found in the center of the TV, the power supply board has several connectors that supply power to the other circuit boards. It can contain transformers, large capacitors, and integrated circuits. There is usually a table on the power supply board indicating the different voltages it produces in addition to the signal names.

Inverter Board

Found on LCD TVs, inverter boards are used to mount the LCD backlight. These are smaller boards, usually shaped like long thin rods. If an LCD TV's screen is dark, distorted, or difficult to see, it can be the result of a defective inverter board. Inverter boards fail when inadequate power is not allowing current to pass through the backlight bulb.

Timing Control Board / Logic Board

The timing control board, known as the T - CON board,, is typically only found on LCD and LED TVs. Plasma TVS, on the other hand, use a logic board.. The functions of the logic and T-CON board are similar, as each functions to digitize the information it receives from the TV's processor. This allows the screen to display images on the pixel level. When the T-CON or logic board fails, the screen images may become distorted, leading to pixelation and the appearance of lines on a television. On a logic board, there are slotted connectors on all four sides, while T-CON boards have connectors on just two sides.

X-Sustain and Y-Sustain Boards

Also known as the X-SUS and the Y-SUS, the x-sustain and y-sustain boards only appear in plasma screen TVs. The x - sustain board might also be called the Z-SUS. These boards function similarly, producing proper screen images. Although they serve pretty much the same function, the two boards work independently of each other. The x-sustain board activates all the display lines at once, while the y - sustain boardaddresses all the individual lines of display. When one board breaks down, it probably will not affect the functionality of the other. However, it might be a good idea to have both replaced because X-SUS and Y-SUS boards have a relatively short life span anyway. A failure of one could mean an impending failure of the other.

Buffer Boards

B uffer boards are also only found in plasma screen TVs. Connected to the y-sustain board, a buffer board works to turn output to the plasma display. Common defects of buffer boards include the burning and shorting of power lines.

When I turn on my tv I get a black screen with red sparkles


Hi this particular model is know for weak sustain boards. So one of your sustain boards is bad. I has two one on the right and one on the left. Most likelly is your y-sus. You can get parts for this tv at www.interliquidparts.com

Hi! Thank you for your help. I have a Samsung TV


Hi Doug Rudnik,

First of all thank you for contacting Fixya.com regarding on your TV problem.

You've mentioned that you can hear a sound for 1 sec and then the unit immediately turned off and there's a constant red LED lit. The symptoms you've described indicates that the main board of your unit is working fine and it automatically shuts off because it sensed malfunction on image boards. The constant red LED means that it is on standby mode only.

Now, since you've replaced the power supply board but still the symptoms persist, then the suspect is either the X or Y sustain board but high chance that the fault came from the Y sustain board based on my experienced. Y sustain board is located on the left side of your unit while the X sustain board is on the right side if you are facing the rear cover. These boards has a ceramic fuse(white color) and pico fuse(looks like resistor), please check the continuity of the fuses to determine which board gone to malfunction. If you found an open fuse to Y-sustain board then you need to replaced it. Blown fuse means that the circuitry on its line gone to excessive current.

I would advice you also to inspect the electrolytic capacitors on these boards. Most of the time loud pop came from a blown capacitor and has a physical indication of fault like bulged/dome at the top and can be easily identify through visual inspection. It can give you an idea also which board gone to malfunction. See sample picture below of faulty electrolytic capacitor with bulged dome at the top.

Hope I've gave you an idea what's going wrong to your set.

Panasonic plasma tv tc p50x1c have white spots


Looks, like X(Z)- sustain board is not working right or at all. If the menu comes on clean, then you may cross off sustain board and main board would be the issue. Are those "spots" ever present, even TV is on video or HDMI input?
give me a little more info, please.
Thanks,
Alex.

How do I test the y-sustain main board from a philips plasma tv...tv model is 42PF7220A/37 the Y-Main sustain number is LJ92-01200A....both buffers tested bad but now I dont know how to test the y-main...i...


Hi.

As such boards are cheap and fail quite easily (both the two sustain and the buffers) Philips service manuals are more oriented at board swapping then at proper testing. In this particular case the buffer boards fail very easily because of a bad soldering to IC. The short will regularly blow the main sustain board.

To start when a main sustain (e.g. Ysus) is fried the TV will go in protect mode with the led flashing in standby. One test is done disconnecting the Sus board (with power off) and restarting the TV. If TV does not go in protect, then the sustain board was good.

If there is no protection:

The first thing to check on a main sustain board is the fuse. If the fuse has blown the IC is probably fried.I believe fuse is F5004. Check for swollen capacitors that may have blown. Test the FET. That is the core of the board as it is the power amplifier.


Here the service manual:PHILIPS_SM_15540.pdf - Right Click "Save Target As"

Here a more useful service manual. Check and follow troubleshooting diagrams in manual.

Here some troubleshooting from users.

Note:if buffer board was shorted, then the main sustain board is usually faulty.

Regards.

I have a 42" LG


Hi,
It can't be fix by replacing the fuse alone because the IC's and other parts are already faulty. You need to replaced the entire Y-sustain board. Try this LINK or obtain it from your local LG Service Centers.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

The fuse you have replaced would have been on the sustain board, now that it clicks indicates a problem either with the control board or the sustain board. You would need to disconnect the connector from the power board to the Y-sustain board (left of power board) to check if the Vs & Va voltages are present, if so then the power supply will be working ok & the problem will be with the previously mention boards. There is the possibility that the plasma display screen could also be faulty.

moz-screenshot.jpgmoz-screenshot-1.jpgmoz-screenshot-2.jpgmoz-screenshot-4.jpgmoz-screenshot-5.jpgmoz-screenshot-6.jpgThis is a common problem on these plasma TV's. The problem resides inthe high voltage boards known as the X and Y Sustain boards.. You canpurchase them here for a very reasonable price:
http://www.discount-merchant.com/Y-SUSTAIN-FOR-42-PLASMA-TV-PN-6871QYH036A-p/sku9510.htm

The above link is to a Y-SUS board. The X-Sus board is often the 2nd cause of failure and can be found here:
http://www.discount-merchant.com/X-SUSTAIN-6871QZH041B-6870QZE017D-6871QZH052D-p/sku9509.htm

Totest which board is failing, you need to check voltage input to theYSUS board first... Input should be 120V from Power supply, outputshould be above 250V.. Do this test with XSUS disconnected. IF 250+Vexists, then XSUS is damaged. If not, then the YSUS is the faulty part.
