Question about Philips 42PF7320 42 in. EDTV-Ready Plasma Television
Most likley y sustain and buffers
Posted on Aug 12, 2009
This is a common problem on these plasma TV's. The problem
resides in the high voltage boards known as the X and Y Sustain
boards.. You can purchase them here for a very reasonable price:
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:
To test which board is failing, you need to check voltage input to the YSUS board first... Input should be 120V from Power supply, output should be above 250V.. Do this test with XSUS disconnected. IF 250+V exists, then XSUS is damaged. If not, then the YSUS is the faulty part.
