Most likely the YSCAN UPPER board and/or YSCAN LOWER Board also gone. Your new YSUS board may damage again if you don't replace the bad YSCAN boards. Try to replace the three boards together and then to verify which boards are bad one by one. Good luck.

SOURCE: p50hdtv10a y-sustain and pcb

I had this problem with a different brand plasma and it turned out to be cracked or missing solder on the power board lead to y sustain. I removed the power board, desoldered the connection, clean it up and then resoldered the connection. Everything works great now.

SOURCE: how do I test the y-sustain main board from a

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.

Ginko

Power but no picture black screen


You should start for the Vs & Va voltages itself. The details to these voltages will be marked on the panel label itself. These two voltages should be more specific than other voltages, especially to Plasma displays. More variations; say; + or - 1%, can effect the display drastically. To get more details about this, you have to download the repair manual to this set, and refer its schematic diagram. If you wish to get some details, check the site linked here. http://electronicshelponline.blogspot.com/ Pull up older posts.

Zenith z50pg10 its dead no click, no led blink nothing !


Zenith Flat panel TVs usually only have two boards in them Plasmas have a few more, doing a visual inspection of the power supply capacitors usually reveals swollen or bulging capacitors.
If the capacitors look good, voltage checks would be needed to isolate the problem to either the main board or power supply. Check for 5 volts to the IR board (& or keyboard) , if five volts is present suspect the main board
If this TV has voltages from power supply , suspect the Z, X and buffers

I have a 25" Zenith


You will need to replace 4 capacitors. Locations and values are C 3460 which is a 25 volt 220 Mf capacitor, CX3218 at 160 volts at 1 Mf (could be 2.2Mf), C3416 at 25 volts 100 Mf , and CX 3413 at 50 volts 22 Mf. In severe cases you would also replace the powerling regulator,(STR-53041) I don't think you need to in this case. Now the green spot you speak of may be the need to resolder the thermistor. I don't recall the exact location. It is a small disk located on the edge of the main board near the power board connection( Your 110 power cord to board). I also believe there is a glass fuse near by. This is a two legged disk that is silver. Take care when soldering this. If it does break you may replace this with an RCA part# 207768. And lastly, when replacing the board back into the TV, make sure you have a good connection to the CRT with the suction cup. It should be tight fitting with no air to escape! Thanks for asking and show a few hands of support!

Sound works picture doesnt. what should i look for


Make sure you have VS and VA voltages from the power supply to the Y main and the Z sustain modules. If they are present then check for 5 volts and 15 volts to turn the modules on. Those can be found on the power supply module.

Zenith Projection Tv Set Model number ZB4685T no Visual


Since this is a CRT based set, there could be a number of problems. What exactly do you mean when you say that the picture fades? Do you loose contrast and the picture gets lighter? or does the picture darken toward black?

Parts are still available, so this can be fixed. If youfeel you want to attempt this yourself, please supply additional info and we'll walk down the diagnosis path.
