Question about Panasonic TH-42PX75U 42 in. Plasma Television

Open Question

TH-42PX75U with a bad SC board price of SC board is $150.00 exchange that is prohibitive, checked all transistors, fusible resistors and coils. FETs seem to read the same Ohms. Has anyone came across a common problem with a specific failed component on this model? Or does anyone know a reasonable cost TV repair tips database that would have most recent models listed three of the ones I tried out did not have this model or problem listed. grateful for any direction. Tony

SOURCE: How do I connect my

If you have a set top box (blu-ray, dvd, cable) with HDMI Out, then you need a pair of HDMI cables. Connect one from the HDMI Out of the set top box to the HDMI In of the sound bar. Then connect the HDMI Out of the sound bar to the HDMI In of the TV.

If you only want to use the sound bar as an external speaker system for the TV, then you should get a digital audio cable (fiber optic cable). Connect this to the Digital Audio Out on the TV (below HDMI ports) and to the Digital Audio In of the sound bar.

I hope this helps. You can find the manual of the TV here: http://www2.panasonic.com/consumer-electronics/support/Televisions/Plasma-TVs/model.TH-42PX75U . The TV also has analog (RCA) audio out jacks labeled Prog Out on the bottom left of the connection panel; the sound bar however doesn't have RCA audio in jacks.

Cindy Wells
(since there are no HDMI out jacks on the TV, there is no other way to connect the sound bar.)

SOURCE: Hi i have problem with my Panasonic TH-42PV8EY- 7

I have not repaired this model. My first thought are bad capacitors in the power supply board. If you do have the exact board to replace. I would certainly do so. Numbers check and you say they are the exact same, should be an easy fix. If this board came out of another TV of the same model, you must remember, it will have the same longevity as the board that does not work. I would compare the boards, and look for bad capacitors on the board that does not work of course. You may check the capacitors with an ESR meter (about 50 to 75 bucks). The purchase and price of one of these will pay for itself. You can fix other electronics. Thanks for asking Alan. I'll be here if you have more questions.

My Panasonic TH-42PX75U will not turn on. It shows no sign of power i.e. red blinking light that I keep hearing about.


Probably the very common failure of the main power supply or one of its outputs. The power supply board is normally easy to identify; it will be a smaller board but with larger parts on it and is normally plug-connected so shouldn't require soldering at all. Panasonic may have new stock or repaired supplies on an exchange basis; call them. The failure mode is mostly caused by the failure of a few cheap components which can be found by any tech owning an RCL meter with loss readouts. I've repaired many hundreds of this type of supply for a dollar or two in parts and not a whole lot of time. It was a nice sideline while I still did this kind of work.

Our Panasonic 50" TH 42PX75U


well it sounds like something fried inside the tv. In my experience, this sounds like your y-sustain board went bad. it could be your video board also. considering todays value of the 50" panasonic plasma, it will be cheaper to replace it, unless you are willing to spend around $300 to get it fix at a shop.
good luck

Check for any loosened terminal of a transistor, IC or a high power resistor in the power supply section. The problem is on that section.

My plasma wont turn on when i try it blinks red about ten times


Your tv could have blown a fuse and or a small cheap transistor or resistor on the main board...Sorry, but you may need a repair service man...Doing it yourself could be dangerous and cause more damage even to yourself! It shouldn't be too expensive to get replaced.

Panasonic Plasma TV - Model # TH42PX77U does not turn on and red light next to power button blinks 7 times - what does this mean? What would be a good estimate for a repair - parts and labor?


This is a difficult question to answer completely. 7 blinks indicates that one of the C boads has failed. however, there are several an SC,SD, SS and SU.
The procedure is to disconnect each of there boards until the blinking is eliminated. The labor charge is usually around 200.00 and the cost of whichever board is bad. Hope this helps.
