Question about RCA VR646HF VHS VCR
I have an RCA VR646HF VHS recorder relatively unused and only a few years old. I can no longer get color out from this unit. I tried the usual... change tapes, change cables, clean heads, tune tracker, try tapes in out units... none of which restored the color. Otherwise the black and white output is great. Any guidance to a solution or detailed repair manual whereby I could do more testing etc on my own. thanks Paul Despault firstname.lastname@example.org Jan 2009
SOURCE: camcorder won't record
Check the tape and make sure the record tab is still on the tape and has not been removed. If the record tab has been removed then use a new tape for recording as the unit will not record. This tap is usually on the lower left end of the back of the tape. When the tap is present it closes a record mode switch letting the system know the tape is able to bv recorded on..

The back lights inverter is working because you can see the "Unusable Signal' on the screen, if the inverter is dead, yoo will see nothing on the screen at all.
If the T-CON (LCD controller) is dead, you will see just gray glowing screen with no pictures or text.
You may have problem with video processor in the main logic board (tuner, audio, source selector).
Parts for your TV:
This is going to be difficult repair since you do have a way to try out the replacement board to be sure that is the problem. RCA service person has that advantage of parts in stock to try out.
I estimate the board from Jimmy to be about $150, from RCA will be twice as much, plus labor.
