I have a Toshiba TP50F50 t.v. that seems to have a loose connection. We will be watching and the picture will go to static or the volume/audio will get loud or softer. This occasionally coincides with movement on our hardwood floors.
At first stomping the floor would bring the picture back. When that became ineffective, I checked the cable/satellite in connection. Wiggling that worked for a while.
Then it seemed the position/pressure on the plastic panel that housed the cable in connector played a part, because wiggling that will bring the picture back.
Now, I have traced the connection inside to a card (like a computer card) that the
satellite in cable is connected to inside. And wiggling that little card will bring the picture back.
Sometimes it seems the back of the set is pretty warm, too. I don't know if heat would affect the connection.
While it is good exercise to get up and wiggle these parts - and my parts :) - I would love to find a way to fix this long term. ANd before I run out of things to wiggle or electrocute myself by touching something in there I shouldn't.
I really love this TV - it is a part of my family, and of course, I am broke, so fixing it would seem a less costly option.
Any suggestions on exactly what part should be replaced?
That is possible - but - I did a work around. Since it seemed that the problem revolved around the cable in connection - I ran an s video cable from my sat. receiver to the tv.

The horizontal line indicates failure of vertical section, checkout the output capacitor of vertical-section connecting to the yoke (vertical) for any loose contact, dry solder, capacitor wear-out.
Need to check the register and filter capacitor that powers the vertical-section.
Do you carry your cellphone when this happens? Maybe your iPod?... could also be static charge on your clothes (not likely, but possible)... like wearing sox on a carpet...
you could be experiencing two problems. the first part of your description states the static with two horizontal bars, this problem is usually erratic and it is caused by a defective varactor tuner(this happens while watching a channel thru your channel selector) the second part that it also happens while using the front hookups could be taht the front input connectors have developed some loose solder connections and thus the video problems (very common problem)
i know your problem. its an inverter loose connection from CCFL to inverter output. back of your LCD inside the TV. try to remove and re-connect again. be sure no power and AC is unplugged. [email protected]
did you purchase these because you thought this was part of the problem? if is a convergance problem you should have some picture it would be distorted or color bars would be on the left or right of the screen. if the light is flashing and you have no picture at all or any audio you have a power supply problem. it is not letting the proper voltage energize the main board.
my guess is convergance ic but to troubleshoot it the best soultion might be to get a can of freeze and spay it on the IC while the problem is happening and or tap the board/ic's to see if you have a loose connection,
I wonder does your screen flash on and off or does the picture just go away? If it flashes on and off it may be that the power supply has a component that has to heat up to work or a loose connection that finally makes contact.
The same thing would happen if the picture just goes away except that a component somewhere in the video circuit could be loose or a capacitor has lost its value and regains it with temperature.
There are a number of things that could cause this problem. This is only a few of them.
