Question about Philips 42MF130A 42 in. Plasma EDTV

1 Answer

42mf130a/37 No Picture

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.

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Philips 42PF5321D/37 Plasma No Picture Six Red LED Flashes

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.
Counting of number of blinks to Philips TVs is entirely different to that of other brand TVs. It is not a direct count procedure. The site have details about how to count the number of LED blinks [Fault Codes] to Philips brand TVs are given; along with details of the faulty circuit location.

Bigscreen won't turn on at all- no LED's, no sound/vid, get a relay click though

It might be the relay itself, you sound tech savy have you tried testing the transformer and various other main board componets?

Magnavox 42MF130A/37, no picture

I'm not sure about the specific problem solution,but I can point you in a good direction, look for 3 legged transistors mounted on heat sinks,they are usually called output IC's or driver ic's. There are 2 in particular that control x and y axis visuals and if they read 0,then they are shorted and need to be replaced. if they are near a metal coil,then ignore the above statement. also,try unplugging the LVDS cable,it's a cable with many tiny wires that goes from the small signal (scaler to other manufacturers) board to the display panel,if it lights,its either the logic board or SSB.

relay clicking is a power board failure --- part of the board still works to supply power to the flashing lights--- the lights are related to an error code while in protection mode

42PF9956/37 SHUTSDOWN...

Ok. I got my tv back on.
I pulled off the back cover and found the relay that was clicking.
I have two blue relays next to each other that click when the power is pushed.
I placed a hair dryer over the relays for about a minute.
Once heated up, it only took 4 tries to get the TV to stay on.
