Sony camcorder switch on and imidiatly goes off!

[[email protected]]

Hello,
I have an old camcorder, Sony Video 8 model CCD-TR45E.
Most of the time, I use it as a camera, not as a recorder. Sinse some
time, I have a strange effect. When the button is shifted to 'player',
the tape can be played and can be seen in the viewfinder, no problem.
When the burron is switched to 'camera', the view finder lights up and
is imidiatly black. Nothing seems to work in this position.
In the beginning (when this problem showed up), I shifted the button
many times and after some time, it worked normal. What also worked was
playing a tape for some time, then switch to camera and the camera
worked. Now these 'solutions' do no longer work, I opened the camera
and cleaned the contacts of the switch, without result.
All sugestions are welcome, it would be a pitty to throw away this
camera just because of some small (but major) defect.
Thanks in advance,
Chris.

Hi. Older cameras have the deflection system of the viewfinder based on high
voltage principles, as the common CRT TVs. If the cameras don't shuts down
completely after switching it on, but the tape can be recorded, the problem
can be on viewfinder section: it switches off but the camera keep working.
If it isn't, then the problem must be found elsewhere...

Check the CRT-pcb. Check the High voltag-part (HV) (250V).
Clean the pcb with alcohol. Check also between pcb and HV-part.
Check the elko's for leakage. Remove if needed.

Hi,
thanks for your reply, however, it seems that I did not clearly
described the situation.
The camera gives also no video output when it switched on in the camera
position. In fact, nothing works if it is switched in the camera
position. When switched to the player position, the view finder works
normal, video output is present etc.
The only problem is in case the camera is switched on: for a fraction
of a secund you see light then it imidiatly switch off.
Anyone a suggestion what to do?
Thansk in advance,
Chris.
