20 Most Recent Panasonic PT-50LCX63 50" Rear Projection Television Questions & Answers

. Try putting you tv set to channel 3 or 4. Try your tv in all modes. Check the back also to see if in the right spots with the wires. Check your channel scan status, try it on anntena and try it on cable, run channel scan on both. good luck. Try vcr wires if cable wires dont work. vcr wires are yellow red and white. Try another cable cord sometimes they get old. Try looking at your remote and setting it to tv.

Hi,
Do you see any light lit solid/ blink when tv shuts down?
Let me know is it Panasonic PT-50LCX63 or any other model?
Above info will help me to diagnose problem and to suggest a solution.
Thanks.

You need to get the bulb replaced. On the left hand side is where you can remove it. Buy a better bulb with the full cage or you will be spending time trying to soder it back in the cage. Bulbs are generally around 100.

How long has the new one lasted.

open it on the bulb hatch remove it it will be broken to look at it usually like a normal light bulb would be ballast requires a meter to confirm it needs replaced

Tv DM power supply board have dead components call capacitors.These capacitors are dying and about to be dead.That why ur tv take long time to take to power up.U know basic electronic and basic soldering?Take the tv aparts take out the DM power supply board searches replaced these dying gases leakages capacitors it bulges up on it tops or puff up on it tops.Ur tv will power up normal again.

Sounds like there is a power problem if the neutral (return) wire on the power supply has become high impedance (or even disconnected) then you will get a high pitched sound coming from the TV PSU also the voltage that is presented will not be 240V which will give you the same problem.

The orange power button means standby if you fix the PSU then the TV might work again but it may have been damaged by the PSU.

Sounds like a fan is not repoting the proper speed to the digital board. Make sure all fans are good. May be bad temp sensor but not likley

Hi,

It means the power management circuit has captured the system and shuts it down when turned on just as fast as possible. The fact that it does not reset is another sign of serious trouble.

However, the power management circuit is likely not the problem; it is just responding to excessive current detection from other parts of the set. Most common is a failure of the high voltage section or the horizontal and vertical deflection areas.

It will need a tech to diagnose precise section and parts that are in trouble. The cost of repairs is usually between $150 and $250 for such types of faults.

Do not despair. This is a fine set. I like Panasonic; it is one of my favorite products. It is well worth the cost of fixing it up. It SHOULD last for another 7 years, so consider it to be a small annualized expense to keep it running. You will have many years of high quality entertainmnet I am sure.

Also this means the horizontal safety circuit
usually responsible for shut downs
is not at fault
if the horiz safety trips you have to unplug the TV
to reset the shutdon status

I would start by verifying your TV is plugged directly
into a wall plug
no extention cords and no surge protectors

If plugging into the wall stops the shutdowns then
go out and replace what ever cord you were using

otherwise you need a TV tech to look at the TV
the problem could be in many places in the TV
convergence IC may be failing
135 volt supply to the horizontal sweep could be low
almost any low voltage supply could have a cracked
solder connection causing random interuption

also I recall nuisence shutdowns with that Model
from the CPU PCB being loose

Left side of chassis all the way to front of PCB
its a small PCB that docks into signal main PCB
and it has 3 plugs that fit into sockets and it does
get loose over time (heating and cooling)

What I would do would be unplug the TV
then remove and remount the CPU PCB
it was that simple

Do you have service manual of Sony KV-30HS510 TV?
service manual shows 2 times error details as follows..

H.OUT (Q5030) is shorted. (D Board)
+B PWM (Q5003) is shorted (D Board)

We had the same problem and found out that we had to replace the Lamp Bulb. The problem is they try to sell you a whole new compartment house with the bulb, but all you need to buy is the bulb (with wires) itself. It will save you a ton.

i would go ahead and have this one fixed if its new enough,,,its in the convergence board where the problem lies and would be cheaper than buying a new tv

I have a PT-50LCX63 unit. After 5 years and 4 bulbs, a "reset lamp" warning showed up every time I turned on the tv. I have to say that after a few weeks, the message ceased on its own. I don't know if all models eventually reset or turn off, but I could not find any other information on the direct way of resetting. I find the warning a waste of time since the bulbs are good for 10 -14 months. Sadly I missed the class action suit that dealt with the premature lamp failures. I am looking for a new tv at this point. Bulbs have cost me $1200.00 since I bought it. The warning is supposed to allow you the option of replacing the lamp before it fails, Ha! what a joke...Thanks for reading.

try these guys out

its due to any of the component on the main power supply board getting overheated.just do not use the tv till it get rep[aired as it will damage the board as if you will use it .

You gave someone the infomation on the web site and told them the part number and the address where it could be ordered. Thank you.

1. Check the Input Source: Make sure you have selected the correct input source on your TV for the device you are using. Use the remote control to cycle through the input options until you find the one connected to your video source.
2. Check Video Connections: Ensure that all video cables (such as HDMI, component, or composite cables) are securely connected between your TV and the device you are trying to watch content from. A loose or faulty cable connection could result in a loss of video signal.
3. Restart the TV and Video Source: Try restarting both your TV and the device you are trying to watch content from. Power off both devices, wait a few moments, and then power them back on. This can sometimes resolve temporary glitches or issues with the video signal.
4. Check for Software Updates: Make sure your TV's firmware is up-to-date. Sometimes software updates can resolve compatibility issues or bugs that may be affecting video playback. Check the settings menu on your TV for an option to update the firmware, or visit the manufacturer's website for instructions on how to do so.
5. Reset Video Settings: If you've made any changes to your TV's video settings, such as resolution or picture mode, try resetting them to their default values. This can sometimes resolve issues with video playback.
6. Try a Different Device: If possible, try connecting a different device (such as a DVD player or gaming console) to your TV to see if the issue persists. This can help determine whether the problem lies with the TV itself or with the original device you were using.
7. Contact Panasonic Support: If none of the above steps resolve the issue, it's possible there may be a hardware problem with your TV. In this case, you may need to contact Panasonic customer support for further assistance or to schedule a repair.
8. Hope this helps
