Problem for Sony Handycam CCD-TRV128 Hi-8 Analog Camcorder

LCD Display




By Authement on May 09, 2006

" "
Only have LCD display when rotated toward front of camera. When I begin to rotate toward rear, the LCD shuts off about half way through rotation and stays off if rotated toward rear. Turns back on at same rotation spot when rotating toward front of camera. Stays on as long as toward front. I don't mind tearing apart if someone can give me a clue(switch,actuater, etc) Thanks

It's definitely in the switching mechanism or the electronics attached to the switching mecanism.

What happens when you rotate the screen is that at some point it has to switch the picture upside down. Otherwise when you rotated it looking from the back it would be the right way up and when you rotated it from the front it would be inverted.

I'd put my money on the hardware which changes the picture. Probably a small microswitch which is activated by a cam on the arm of the LCD. A little squirt of electronic contact cleaner could put things right. If by chance it's a finger type switch (2 spring steel fingers which are activated by a cam) the same contact cleaner and maybe a retentioning of the fingers. I often use just a piece of printer paper between the contacts, close the contacts and carefully pull the paper through them. This will clean off any gunk built up. (you'd be surprised at how abrasive printer paper can be)

sounds like a torn ribbon cable or connector.. You said you didnt mind tearing it apart?? have you taken one apart before?? As its not that easy as you may just tear it appart if you dont follow an dissasebly guide. tester ribbon cables and theres many, are also needed to operate camera and deck in a disassembled form. You really should get someone who works on these pups all the time.. to give ya an estimate. Good Luck

Had the same problem on mine. I am no electrical engineer, but I noticed a burnt circuit above the flash towards the front of the camera.

The flexible LCD film connecting strip is defective.
I think this is fused to the LCD and you need to replace the whole unit.

I pretty much have the same problem.

1 month after the warranty expired, I began to have this issue. At first the LCD would go blank at certain angles. (Actaully the whole display would turn white) Tghis continued to get worse until the LCD basically didn't work anymore.

I carefully disassempbled the shell of the LCD panle and found that there is a tear developing in the FFC (ribbon cable) that connects the LCD panel to the rest of the camera. The FFC is actually wound around itself like a spring where it passes through the swivel for the panel. Unfortunately it is rubbing against the edge of the swivel and the swivel is cutting into the FFC.

I did get a factorty repair booklet from Samsung, but it does not have clear disassembly instructions.

I did disconnect the one end of the FFC to prevent an fatal short from occuring. The camera still works just fine, but I cannot ise the LCD panel.

I am waiting until I transfer all my tapes to my PC before I go any further with the repair.
