    TV goes into Standby and will not restart (Panasonic Quintrix) NB I have no remote

  • Anonymous Oct 23, 2008

    Standby circuit keeps activating to turn the tv into standby, usually after 2-3 minutes when cold, once warmed up it only stays on for around 10 seconds

  • Anonymous Nov 10, 2008

    Trying to switch on from standby but after a few seconds the TV just puts itself back on standby - Help!

SOURCE: i have a panasonic quintrix

The first thing I would check is the line output transistor this is the large transistor mount on the heat sink next to the lineoutput transformer (the big black thing with the lead going to the side of the tube) just replace it if you have no meter to check it.

How to connect laptop to panasonic quintrix


An AV cable should be used, if the Quintrix TV you have AV input sockets. If there is VGA input with the TV, you can connect to it too. images of both the cables are shown.

I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have tobuy and try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.3_30_2012_12_36_36_am.jpg

Condensation on the circuits needs drying off by using the TV. There maybe also contact resistance preblems which needs vibration from the side of the TV to get it working right.

I have a panasonic quintrix tv tx28dk2. When i turn it on it turns itself straight onto to standby repeatedly.
