Hi, me again - further to my previous question, checked y sus board compared to z sus board - z sus "fizzes" (50 Hz) under the big heatsink, but the y sus board is silent. 5V, 60V and 186V supplies are all good. I've fried my devices under that heatsink, I reckon, as there's no other sign of damage.
Whadd'ya think?
Hello... Fried devices on the y sus will usually blow the fuse on the y sus. That would explain no fizz. I hope this helps...

I have dealt with Lg in the past regarding screens and they are unable to sell them as a spare as they are so expensive, they are only used in production and a complete new HD TV is cheaper to buy than a screen. for example LG37LP1D £900.00, a replacement screen £1500.00

Your Vs voltage is high, check if the heatsinks on the Z-sustain board are getting hot after a short time, if so replace the Z-sustain board. If not, dis-connect the Vs & Va plug connection to the Y-sustain & check if the voltages are normal (185V & 80V). If they are then your fault will be in the Y-sustain board. There is a possibility the control board (sits below the power supply) could also be a problem as it is not able to initiate the control to the sustain boards.

The Y sustain should have a ceramic fuse, possibly 2 and the Z should have one also. Leave the set on for about 20-30 minutes, then shut it off. Feel the large heat sink on each of the boards. If either is cold then that's the culprit. Encompassparts.com has these boards in stock. The Y is 250.00 and the Z is 168.00. A word of warning, the Y can also destroy the Y drive boards also, which are located on the left side next to the Y sustain. Sometimes you can see small pin holes on the driver ic's on the driver board but not always. These boards are non-repairable by us techs and must be replaced when bad. If you have any questions e-mail me at [email protected] I strongly disagree with used parts in any Plasma set.
Testimonial: "yes, i will test after the gym... thanks i will contact you by email."

Here are the service manuals:

If the power supply is not made by LG but by other OEM, then it will be hard to fix.
There should be a pin on the board usch as PS_ON or somthing like that, it should have 3.3~5vdc on this pn to turn on the 24vdc and 12vdc section on.
