TV powers off after an hour or so

Per advice yesterday, we took the back off an tapped on the circuit board to find a loose connection, etc. Everything looked fine. TV stayed on for about 1 1/2 hours or so. The SECOND I went to move the circuit board the TV shut off, requiring us to unplug it, wait 15 minutes or so, and plug it back up...dont see any dark areas on the board and have wiggled all cables and cannot recreate the problem in a specific area..any suggestions?

Hi Chuck, intermittents will definitely try your patience, It`s obvious the problem is with a poor solder connection or loose plug/connection. It would help immensely if you would tell us make and model number of the set. From your description I would unplu AC cord flip the main board over, get a bright light and a magnifying glass and start checking your solder connections, I`ll bet you have several, check closely low voltage power supply area (where your AC cord attatches to the set) and the high voltage area where the flyback is (large plastic part with large red or black wire coming out of the top), your looking for connections that are cracked or dull grey (overheated) solder, if you need more help keep asking thats what were here for, good luck, BMW Rider

    Chuck, that one is infamous for bad control board tact switches, the little board way up front that has , power button, volume up/down, channel up/down, etc. If you don`t find obvious bad solder connections try this, un-plug ac cord, remove control board screws where it attatches to front of set, and then let board hang off to one side so it`s not laying on the main board, plug in set, turn it on and then twist and turn the cable on the control board, tap on it with a screwdriver etc. to see if it acts up, if it does let me know and I`ll see if the module is still available for your model set, (way easier then un-soldering all the switches and re-installing new ones, let me know, BMW Rider

How to determine if a plug on the back of a TV is good


Have you checked for a cracked circuit board. Very minor cracks in a circuit board may cause a break in the circuit when the boards are flexed slightly. Loose solder joints will also cause problems when boards are flexed or stressed when screwed tightly etc.

Powers off after an hour or 2


if the second you moved the board it powered off would really make it sound like a cold solder joint or loose solder connection
they are hard to find, take the board and tip it so you can see it and
move a plastic handle of screw driver over the solder joints while the set is UNPLUGGED and look for and old discolored solder joints and any hair line cracks you can even flex the board to see if you can find it... look very close it will be hard to spot.

Westinghouse ltv-32w6hd tv i only get power light,, the guy i got it from said the color would sometimes bug out and he had to slap it for it to go back, it got worse over time and now no pic, i only...


Almost any device that has to be slapped around has a loose solder connection or a loose connection somewhere inside (could be a loose cable, like the lvds cable) or something similar. In very rare cases, it is something loose inside of a part and you will need to replace parts, but it is probably a solder connection or cable. solder connections are more difficult to fix, especially on the more complex circuit boards. a loose wire is easy to fix, so that would be your starting point. if you feel so inclined, lay the tv down on something soft face down, careful not to put any pressure on the fragile screen. you may have to remove the stand if laying it on the floor, use a blanket, etc...
take all the screws out of the back, some models you have some on the bottom, but most will be going straight in to the back of the tv. pull off the back, and then "reseat" all of the cables.. reseating is just unplug and replugging them to ensure they're all clicked or pushed into place. in some cases, they will be clicked and still need reseating.. make sure you look for locks, clips, etc on the cable ends, and be careful not to break any.
from your symptom, it sounds like it could be the LVDS cable, that goes from the main board(with lots of small circuits, maybe the inputs, etc) to the TCON board (one that drives the screen).. this is the most fragile and also the most likely to be causing this issue. ..

look to see if your tv still has backlight, this is even more likely the cause as you have power, backlight, just no picture.. if you dont have backlight, suspect the power or inverter boards, but still could be main. if reseating cables gets you nowhere.. use an insulated handle of some sort (plastic screwdriver handle (insulated)) to tap on the boards and see if the pic comes back, if you can get it back this way, could be a solder connection..

let me know what you find.. you can look for bad caps also, these are always a red flag - should be flat on the tops

Tv turns off by itself after few seconds has been turned on


tv turning off automatically
for first unplug the main power cord of the tv for couple of minutes and then reconnect it.also before reconnecting the power cord of the tv again remove all the external device wires connected at its back such as dvd player/vcr etc etc.just connect only tv wire and check out.if still the same problem then its quite possible that the capacitors and ic on the circuit board are getting short in between so the circuit is not getting completed and cutting in between so the tv power led comes but no picture comes up..in this case the circuit board needs to be checked with a multimeter.the faulty and burned out component part should be detected and then should be replaced with the help of soldering iron.to make it proper.to avoid further damage i suggest you that do not on the tv again and again as it will short some more tiny components and the reparing cost will increase as per that.at present its the normal circuit short problem in the tv get it repaired before using the tv again.

Red and Green vertical lines (pinstripes) on video source only!


I had this problem, I just fixed it myself. I'm am not a tech or a pro by any means, but I am short on funds and repairs were not in the budget. I figured I had nothing to lose so I wanted to share what I did and maybe help someone out. This is to be done at your own risk, you could shock yourself or break something else.
First off, I had the conversion circuit changed a few years back. These TVs are famous for them going out, so I knew it wasn't that.
I removed the back of the TV and the plastic part that houses' the connections (RCA jacks, S-video,etc) Behind that there is a circuit board standing vertitcally incased in a metal case. I simply wiggled it back and forth and the lines went away. That told me that something was going on there.
I removed the circuit board that had the RCA jacks to make some room( I would'nt force anything in there, take your time and be sure to unclip the circuit board) I then unscrewed the "metal case" and took it apart. I dusted everything and put it back together exactlly how I took it apart. I then cleaned the lenes.
It works great now and it only cost me a hour of my time. The picture is as good as new. I hope this helps somebody.

You have a bad connection on the CRT board thats mounted on the end of the picture tube it sounds like, or the socket on that board that plugs into the TV set is intermittant or has a bad solder connection on it. Good Luck
