Only lines on upper part of the my screen


With the limited information on your issue and no voltage checks from within the TV, the best I can do is suggest the following.

sounds like a Ysus board issue and/or Zbuffer issue.

If it's the Zbuffer, change the Ysus card along with it as it could be the reason why you are having buffer problems.

While a buffer problem alone will not affect the Ysus card, a Ysus card issue will continue to blow Zbuffers if that's all you change.

check to see if it's still under an extended warranty, if not, then find the service manual for your model online and see if this is something you want to DIY.

Flat Screen LCD TV has picture on top half, black on bottom.


You turn on your beautiful LCD flat screen and when it boots up it has a picture on the top but nothing but black on the bottom. What is wrong?

Since the top half of the picture is working we know that the circuits which drive the signal and display are OK. They are the same for the top and bottom.

The difference is there are two YSUS drivers for the unit. One on the top and one on the bottom. They are referred to as the Upper and Lower YSUS drivers. They provide the signal to the display. You have lost the one on the bottom.

Unplug the unit and lay it on a flat padded surface. Remove the rear cover by taking out all the screws around the perimeter. Some screws in the center of the back may have to be removed. They should be obvious.

Once the back is off look on the left side of the unit. There should be separate boards (split top and bottom) which are the YSUS drivers, top and bottom. The boards are only about 1 to 1 and 1/2 inches wide and occupy 1/2 of the space from top to bottom.

You may have to remove the YSUS board, and maybe even a support beam to get the driver board out because the Upper and Lower YSUS boards are usually located under the main YSUS sustain board.

If you go to http://www.encompass.com and input the model number all the parts will be listed. There may also be a service manual available for downloading and you can scroll through the parts to find the Upper YSUS board. In addition the board should have the part number on it.

For Panasonic it generally begins with TNP-XXXXX. Your other option would be to look for the part called "YSUS lower driver" . Order this part and install it and you should have a working set.

I have a tip at http://www.fixya.com/support/r6981868-replace_circuit_board_in_modern_tvs which explains the proper procedure to remove and replace a modern electronic circuit board.

Thanks for using FixYa and for the great rating. Please consider a testimonial. Thank you.

Picture went out on Vizio P50HDM


Check you voltages before just swapping out boards. Although a YSUS is common for no picture, so is your upper and lower Y Buffer boards or the panel itself. Check youe -VSC voltage. Does it look like it is being loaded down? If so then your YSUS is not the problem. You can run the set with just the upper or lower Y Buffer boards untill the load is gone. That will let you know wich board to replace.

Screen got black lines across it


Across vertically or horizontally... It makes all the dif. It could be 3 boards on the set. The YSUS-main the YBU-upper/YBL-Lower. The Y buffer upper controls the top half of the screen, the Y buffer lower the lower half and the YSUS-main controls those 2 boards. They work in unison, when one goes they all fail. The other possibility is dry solder joints on the the D, G, E, F boards. All you would need to do with that is reheat the solder joints at the ribbon cable conx.

My tv lost its color and has a black spot on the screen, can I do to fix it?


Sounds like you YBU-YBL (Y-Buffer Upper-Lower) and the Y-SUS/Main is out. The Y buffer upper controls the top half and the YBL the lower half. The YSUS control all of this. The YSUS is also connected to of course the Power supply board and the logic board.

My 5 years old Plasma TV found half of the screen picture view not very clear.. The half colour seen blur..


Your Buffer boards or the YSUS main are bad. THe YBU-Y Buffer upper controls the top half of display, the YBL-Y Buffer lower controls the bottom half and the YSUS Main controls both those boards. They are located to the Far Left on and opened Set.

LG Tv 50PQ30 the lower half of the screen intermittely stops working


looking into the back of the tv with the cover removed, there is 2 boards on the far left the run down the back of the screen. These are the Ysus buffer boards.They both plug into a larger board (Ysus). Make sure that the bottom buffer board is pushed into the Ysus properly and that the wired lead connecting the upper buffer board to the lower buffer board is pushed in firmly.If this doesnt solve the problem then you will most probably have a faulty lower buffer board.

Philips 42PF9630A/32 Plasma TV RED led blinking 7 times


Are there any blown caps on the PSB-power supply board. Most sets have sammy boards and they used very shotty caps. If there are no visual clues being a poped cap at the top (X) they simply often do vaporize and dry out. The YSUS-Main and the 2 Y buffer boards control the picture OSD-on screen display. Your not getting any of that. So power supply is where you start first. The YBU-upper and the YBL-lower control the upper and lower OSD the Ysus main control both of them. Usually if you have one in the door you have to replace all 3. But not always. If you were to replace any of the boards I would replace the YSUS-Main, or get the board reworked at a pc repair shop that does board level test and repai. Its more cost effective.

50 " Phillips Plasma tv. Screen is black, blinking red light.


Sounds more like blown/exploding capacitors on the PSB-Power Supply board. No OSD-on screen display a blinking led or chatter/relay clikcing at startup is the tv going into fault protection and bypassing the startup pins. The YSUS-Main controls the pic which is attached to 2 buffer boards the YBU-upper YBL-Lower. They control the upper and lower portion of the OSD and the YSUS controls both of them. Since you're getting No OSD you need to check for blown caps on the PSB first. Unplugging the set resets the error again. So you start all over again.
