Question about Philips 42MF130A 42 in. Plasma EDTV
When I turn the power on the led's go from red to blue and I hear relays firing on the main power board. However one relay apears to kick back out after detecting some type of fault. This all started while connecting RCA's to the set while it was powered on. Heard an electrical sound and smelled burning electronics but nothing is visibley burnt. Any first steps of what components to check. I am very savy with a multimeter and have an extensive electronic background.
It cound be a number of issues, I would venture that its one of 2 expensive units that are prone to failure. The main board (as its commonly called) should be a 715p1511 with a dash and most likely a 1a.
They are expensive to this day normaly around 100-160 depending on where you shop.
The second thing it could be exspecialy if you have not seen burning. is what refered to as a logic board or scaler board its behind the main board under the metal bracket that holds the main board. It is also in the 100- 160 range for it.
If your hearing the relays its most likely not the power supply falt due to there very robust in that system. If your going to put money in it i would go with the first two mentioned. and see.
Now with that being said. I have one of these same models 42mf130a/37 that was in a vacation rental unit. IT had an accident (no one omitted how it happeded) but the screen was busted like a baseball hit it (maybe someone was playing wii, who knows.) I have removed the boards to part out to recover some extra money to pay for the difference in cost of replacing it(insurance only covers depreachated value). I listed that main and logic board on ebay this evening but i doubt your still looking for the part.if so its the main board is here.
