Mine IS a VLP-970 HF. I DID like the way it worked...a few years back. But it has NOT been powered on i a while...since the tuner...then display...died. Likely...caps bad, or if it uses that DC converter module to provide tuner/display power, maybe it died.
From what I have learned our VCR's were the "cat's meow" for 1986...at WELL over 1K new !! I got mine cheap...maybe - or so years back...just needed the load belt....THEN. |

im glad to hear that you liked yours it sounds like yours may have the same problem mine has, im thinking the part that helped bring it back was taking apart the little press fit ribbon cable sockets that connect the two logic/clock boards and scuffing the internal contacts with a scotch pad and a flat head jewelers screwdriver. they look like regular 2 part plug and sockets where the cable is crimped into a plug but they are not! i almost broke mine by prying it apart, just press down both sides of the socket and the cable will come out without bending the wires. mine looked like the contacts were made out of copper but plated with solder but it was flaking off and causing a bad connection. i also found a short and stubby blue matsushita cap below the giant hitachi ic that had leaked and somehow started eating the traces on the back side of the board i think it may have been a filter cap supplying power to that main ic i will have to post pictures for anyone else who runs into this issue that wants to fix it |

this should help you fix your vlp970hf if its like my 950. first is the board with TIM printed on top i found a matsushita 330uF 10v electrolytic at C110 on the board that i replaced. im not sure how but when it leaked it darkened the solder mask directly behind the capacitor and started eating into the copper so after i replaced it i scraped off the corrosion and tinned it with solder. my only guess would be that since the cap was near the bottom edge of the board that when it leaked the fluid must have wicked up the back side behind it

this shows the two press fit connectors that might have flaky platting on them. i almost broke mine the first time by pulling so hard that the hook side slid past the back plate and so i had to go back and re seat each one. i think it actualy helped the cleaning process a bit though by exposing the part that bites into the wire to hold it in place if all that makes sense

i should also point out that all through out the case i keep finding these sort of smoke marks. they seem to come from transistors and resistors that run hot but i also wonder if it is from the electrolyte in capacitors. the area pictured is by far the biggest area and its above the power supply. its not the regular burn marks i see in other gear but a fine dust like residue that wipes right off.

I DO recall a burning smell...fro mine...when it died...i did NOT know where it was coming from...till the VCR went dead...
it is VERY likely mine is the same as yours... Not sure what is different about mine. it has HI-Fi and 7 heads I think...and OSD set up...not a common feature at the time it was made (yet) Maybe I will look at mine soon. like I said..015 was a ROUGH year for me...especially the last couple of months...I PRAY 016 will be better. |

That module probably has an electrolytic cap associated with it. If it goes bad it would take the module out as well, so when replacing the module replace that cap too. Had an RCA VCR where I had to do that
