Question about Samsung PPM50H3Q 50 in. HDTV-Ready Plasma Television
Hello,This problem happens when the voltage of pin 1 of IC804 is low. The low voltage is caused by pin 4 not being 20V this is caused by two capacitors not functioning properly ( a 22uf cap in parallel with a .1uf cap) replace these and replace the 24K ohms resistor with a 44K ohms resistor (as per update specs). This should bring pin 4 to 20V and allow the set to activate. Replacing the 24K with a 44K is recommended by the manufacture to prevent the cap from going bad.Or if you do not want to do this yourself have a qualified TV technician do this for you.Thank you,Shuttle83http://www.electron-age-technologies-llc.com

When checking the capacitors, If they are slightly rounded on the top where the X is, the cap is defective.
To repair or replace the board -
Faulty parts on PS board , bad press for Samsung.
Because the Samsung LNS4051D would not turn on and the power
LED would blink 4 times and the relay would click and this
would repeat again and again. I replaced power supply board
parts CM806, 811, 812 & 817, all 1000 uf 10v capacitors,
three had their tops bulged up slightly that I missed on
initial visual inspection. After seeing the reports of
problems with these caps on
I replaced them with Radio Shack part 272-1032, 1000 uf, 35v.
They are slightly bigger, but fit OK. TV is working fine now.
Cost was 4 x $1.59 = $6.36 plus the time. I saved between
$100 to 300 in the process of either replacing the board or
getting the unit serviced. If you are not comfortable
replacing components which means using a soldering iron, you
can replace the power circuit board, available from
Some UTube showing the problem and fix -

This is an internal error. If all the three lights are blinking, the sub power board may be bad.
