    i have a older hitachi ct-7893bc that was given to me, when i plug it in and power on the screen tried to come on but shuts back off within seconds, then if i try it again after that all i hear is the relay clicking on the power board, i tried swapping the flyback transformer but it is still doing the same thing, i have a board here out of the same tv so i have no trouble getting parts for it.

    any ideas on what else i can try?

Cause of vertical collapse on glendale tv chassis


collapse means just a white line left to right in middle of screen--usually a bad solder connection at the vertical output chip or a bad part in that area.

Picture goes to a single horizontal line.


Your problem is due to failure of the vertical scanning circuits in your TV. This is quite common and is caused by aging components. Generally drying out capacitors
You got to be careful not to leave it on too long when the picture collapses, it will burn a permanent line across the screen.
If you are an electronics expert you can fix it if you get a schematic. If not please don't attempt to reapir it yourself since there is high voltage in side the TV.
The problem may get worse with time.

My tv is 2 years old and in the last month or so in the middle of a show the screen will go black and a red line runs down the middle and it lasts for about 5 min and a little pop sound and the picture...


It appears you may have had a line collapse caused by a poor connection in the line output stage, it would be a matter of resoldering around this area. Now that you say it will come on could indicate that a component has now failed as a result of the line collapsing, more than likely the line output transistor has now also failed & would need replacing.

Hi.

Just read your list of problems The first fault (Diagonal lines & picture collapse from left & right) Sounded like either A poor connection or dry solder joint either on scan coils or scan coil plug / socket on main pcb.
If this were the case the engineer that called out should have spotted this & sorted it very easily. But you say it is still the same so what did he do ?
Did he give you a reciept with break down of what he did ? If yes please post it here for me to go over.

The sound problem you describe has thrown me a little so could you please post your tv model number on this page so I can see if this is a stock fault.

The static shocks you are getting is relatively normal & not a problem unless you are getting them off of speaker grilles or even tv casing if it is silver in colour.
I am UK based & have access to samsung technical but I will need your tv model number.

Mitsubishis TV Problem


have a Mitsubishi TV 1993. Model CS-35301. The problem is that there is a white line that is running through a blank screen. The sound is fine just no picture. Have you heard of "Vertical Collapse?" I would love to save the TV. Hi nothing to worry just minimise brightness to avoid screen burn. "Vertical Collapse?" means one bright hor.line in the middle of screen. this problem can be solved 1 check vertical yoke connector or wire loose 2 check supply to vertical section which normally comes from EHT transformer check components in vertical section or print loose regards thanks
