Question about Panasonic AG-DS555 S-VHS VCR

1 Answer

Seems like TBC won't lock, blue cast, picture unstable, weird colors, no contrast

I just got this deck and I love it. I'm a ham guy/computer tech., have solder station, can perform surgery.
You mentioned replacing all the caps on the vid boards. Before I do this, I notice lots of internal trim pots. Is it possible the unit needs a tune-up? Seems to get more stable after warmed up -- jog/shuttling back and forth will eventually get it to lock on. Does it playing tape as well as video in, so I'm convinced it's in the output somewhere -- TBC, video out. This deck won't let you turn the TBC off? Tried the setup procedure from the user manual for the TBC. Any help appreciated. Sounds like you really know your stuff. Actually, mine is the AG-DS550. Cheers, Duncan McAllister

Change in stability after warm-up is a sign of defective capacitors. the DS550 and DS850 both are notorious for capacitor failures. don't touch the trim pots unless you have a service manual and a wfm/vectorscope.

92 geo tracker keeps blowing fuel fuse 15 amp but when I go to a 20 amp it is fine gas tank is haff full of fuel what is my problem


first off each fuse has a name , so what is the correct name, the 92
has 3 EFI fuses, DOME (memory) IG-Coil (ecu and spark) and "FI"
never up the amps ever or burn the wires up. sorry but that is a FACT. the a above data is wrong, this cars pump draws 4amps.
if more its bad, sure if over 15 it blows, but is a bad pump.
all pumps like to do that, they burn up and suck power, like a piggy.
see your fuse here, linked,
this car and ECU nor know for shorted pumps and shorted ECU
the 92 uses these JUNK brand caps, large electrolytic caps.
and they love to short, on all 89 to 95 trackers and sidekicks in usa.
they are marked Rubycon.

so again which fuse?
ill pretend its FI blown

http://www.fixkick.com/power-elect/blows-fuse.html#FI_blows

FI is bottom right, lost the cover? now you have one.
http://www.fixkick.com/Elect-fail-index.html

is engine 8 valve or 16?, they have different EFI , systems.
Im sure its FI, as it runs ECU and pump. so..... and they love to blow.
25388833-rc0a3iye2lzfx2xdaq3zufia-1-0.jpg

ok i throw dice for you, land on 8v.
see 8v FI fuse here?
http://www.fixkick.com/ECU/8v-tbi-schematic91to95.jpg

what i do is remove the left rear tail light,lens.
then see the pink pump wires, I measure the pump current
i reads 4 amps, with helper keying on over and over.
see?
now if near 4amps, then the ECU is shortings it CORNER cap.
http://www.fixkick.com/ECU/ECU.html

the caps dry out,inside, leak acid , wreck copper traces
and then the cap shorts, some times , it loves to short on speed bumps. due to vibration, its just a bad 50 cent part
that any tech can change or any HAM radio guy, etc.
with simple soldering tools and skills
do tell engine type G16a or b (a= 8v, and b = 16v) and we can
point to exact part bad.

Cant get a full signal because man next dor is a radio ham and blocks our signal wot can we do we have boosters and new arial


Unless you are in channel 2 (does not apply to USA any more) and he is transmitting on 10 or 11 meters,you may get some interference. If he is not transmitting, there is no way he can block your signal to the TV. Make sure all your connections from the antenna to the tv are ok,or try directing your antenna to another channel(location). Unless you live to far from the area where the majority of stations are,try with a smaller antenna close to the tv to make sure you have everything connected accordingly. We ham radio guys normally are very friendly if he is a ham radio guy (not a CBr) I am positive he will help.

Bang and Olufsen 1980s Sound System. Broken input jacks for turntable. Broken Tape deck. Local repairers say they can't repair it because no spares


You will have to pay for the labor, if it's just truly broken RCA phono jacks, you can have them replaced by any ham radio guy or electronics guy with a soldering iron. It won't look perfect, but it will work just fine if it's only the jacks and not the switching circuitry. Radio Shack even carries (carried) single RCA chassis mount jacks to fix this.

Black lines across the top third of screen for 30 minutes till the TV warms up


Bad or leaking caps per an LG bulletin was issued for this model and all three series units of tis model. You'll need some test equipment, mainly a cap analyser 88, solder station and some expereince in SMD components to fix this unit. But it can be fixed, not an expensive fix, and if you're not too sure how to do it take it to a qualified tech... Let em know there is a bulletin on this unit...
Good Luck!

This is probably caused by faulty capacitors in the power supply. This is a common problem with this model. If you no longer have a standby light, it could also be caused by an unidentified short on the main board. Hope this helps you out.

Need to replace power plug in,what is the best way to take the computer apart.


Ebay is full of replacement power jacks for laptops. But you need to find a competent electronics tech with a good, fine, temperature controlled soldering station.. Ya dont want to get out the big old soldering gun and have at it yourself.. unless you can afford to really mess up your laptop's board..
