Question about Televison & Video

3 Answers

Protron pltv-32c won't stay on. It is stuck in some power loop. What it does is it turns on, then immediately turns back off and is stuck in this loop of turning on and off. I have already raplace the power supply and that isn't the issue. Please let me know where to check next. If someone could get me a service manual that would be great!

I believe this is the service manual for your Protron PLTV-32C.
Just click 'FREE' to download the file after selecting the link; this manual is too large for FixYa to host here.

It is listed by a different name, but after I got a tip that this is the model that is marketed under the name Protron or Spectroniq, I downloaded the Protron's user manual, and the TVs & remotes look the same to me.

I hope that helps.

Hi,
Most likely then your main board is the problem. Being the overall quality and original price of the tv, I would purchase a new tv. Though you can keep throwing parts at it, it is all personal preference. I always recommend researching a tv online thoroughly before purchasing. Always purchase from a reputable company. Saving a few dollars on the front end of a tv purchase can cost you more in the long run. If you need further assistance let me know.
Thank you,
Lee

    This is a tv that I got for free. so it's worth the fix. I just need to pinpoint the problem. I have a service manual for it but it doesn't tell me too much about servicing the boards and the troubleshooting section has nothing in to remotely related to the problem I am experiencing. there are only two more boards to consider. The backlight inverter board or the video i/o board. Let me know if you could help me.

Above is your user manual, below, your service manual.This manual is what the engineers use to troubleshoot and repair these sets. www.managemylife.com/mmh/lis_pdf/OWNM/L0604891.pdf
Please use these manuals in particular the service manual, The service manual, has troubleshooting steps that will soon allow you to isolate and hopefully remedy your issue.
With, any electronic repair, we must as you have so correctly done start at the Power supply so you have done very well. However usually, we have a "SYMPTOM", and a "Cause" the symptom may be a "Blown PSU" the "Cause" may be a defective Capacitor, IC, Transistor, resistor, that is drawing too much current, and is causing the power supply to, shutdown, and or Damage that too. So we MUST always Find the "Cause" FIRST, then repair any damage done by that "Cause".So in effect, we have two problems, the part(s) that are faulty, and any Damage caused by them.

Hello, there is a default password, if you source is in component 2 it can't be used here are some links to the pdf file pltv types.
V-Chip Lock When turned on, blocks access to mature television and movie content, based on the MPAA and TV PG ratings selected below, unless the viewer enters a password (set below). Set Password Sets the V-Chip password. To change the password, enter the current password followed by the new password. The factory-default password is '1234'.

Hi have a protron and can't seem where the plug to connect it is can you please help me


You mean that you don't have the A/C cord running out the back? If not there is a small black hold in the back of the set that you have to plug this type of cord in, if you don't have try places like walmart, home depot, or any electronic store.

DTV Converter Box


If there is no digital tuner built into the tv or unless you subscribe to Cable TV or Satellite service you will still need a converter to view tv with rabbit ears (air broadcast).

Good luck!

funny that no one's been able to help you, because I accidentally discovered that the power supply cord for my computer worked for my Protron PLTV-32C lcd...  not sure if your model is different in someway, but you may want to try the cord from your own PC first, 
and if it works.
