I have a 42 in Sanyo DP42647. If there is something like a logo or words that stay on the screen for more than a few seconds it looks like it is burned in. It eventually fades but by the time one fades...


Cause of screen burn typically is pixels are no longer showing full range of color. Typically a shop would cycle screens or blocks of very bright colors alternating colors to unstick any pixels not showing full range of some color. Setting tv back to factory default then adjusting could help also turning up brightness. Change color settings from cool to warm could help. Could also be a refresh rate. Verify tv is set to display at same rate as input device like cable box set to output 1080i while tv native is 720p. Just because there is a pic doesn't mean they are synced.if tv has to convert signal from 1080i to 540i then resize to fit 720p tv it may slow refresh rate tv is trying to display progressive scan image but not enough data is coming in so it redisplays previous image on every other line.and new data on every other line.
solution is check output video settings of source to match native resolution of tv. Hd cable box this is common as tech sets output to high resolution 1080i most inexpensive tv are 720p

No charge voltage to battery. New alternator. No turn signals. This vehicle lost charging when towing trailer.


Troubleshoot by isolating the alternator, then testing for a 13.5 - 16v output (likely to be ~14.5v). Anything out of that range indicates bad alternator or voltage regulator (assumed to be built into the alternator). If voltage is in range, (and following your suspicion of an electrical problem in the Turn Signal circuit), reconnect the alternator and isolate the turn signal circuit by pull the fuses. See if you are getting the good voltage reading of (~14.5v) at the battery. IF IT'S GOOD..check for bad trailing wiring harness (isolate if possible), I've seen bad turn signal bulbs (contacts on bottom of bulb) short out (melt) in their sockets (typically causing a blown fuse..but ya'never know), and lastly you might have to do a hand over hand following the wiring, looking for shorts, melted wire, cuts, broken connections, etc (see Hanes Manual Wiring diagrams for possible points to perform continuity checks). IF IT'S BAD. you must continue to isolate electrical circuits until you find the one that is causing the fault. You can pull one fuse at a time (not reinstalling them) until voltage at the battery returns, or you might try pulling a group of fuses at a time until you can read good voltage at the battery, then replace the fuses one at a time until you find the bad circuit. Once you've isolated the bad circuit, it's either a matter of further isolation until you find the bad component (many circuits supply voltage to multiple components), or checking every connection and component connected in the circuit. Best of luck resolving this problem.

Why is my batt not charging and when i jump it it conks out and its new bike


Well, my first response is that 2005 is not NEW. Hasn't been new for 6 years!
There's something wrong somewhere in the charging circuit.
Check your regulator module, and check the voltage coming from the alternator (magneto).
Make sure all the wires in the harness are connected properly and none of them are broken.

The battery warning light has come on and the gauge that shows the charging level seems to be lower than previously


Hi, You have problem with your alternator ( charger) . Seems the voltage output regulator work failed. You can check the output voltage of alternator by using DC voltmeter and it should read between 12-13.8 VDC. If the reading below that range your alternator is malfunction and need to repair by experience people. Regards

Anyone have a picture of the alternator on an '03 Tundra V8? Trying to check output - losing battery V overnight.


Start the engine and check the voltage at the battery with a volt meter. It should read from 13.5 to 16 volts. If it reads out of this range the alternator is defective. If the output of the alternator is ok, then you have something that is on and is drawing power overnight. Dome light, under hood light, glove box, brake light, etc. It can also be a relay that is stuck as in a P/W relay.

MY CHECK CHARGE SYSTEM LIGHT AND LITTLE BATTERY LIGHT KEEPS GOING OFF. I'VE HAD THE WIRING HARNESS TO THE ALTERNATOR REPLACED, THE VOLTAGE REGULATOR REPLACED AND TODAY A NEW BATTERY PUT IN. NOTHING IS...


The first question for you is, What is the charging output for the altenator at idle?? If less than 12.3 volts, replace altenator. Typically, the altenator gets tested at 2500-3000 rpm on a bench tester. Your problem may be in the low rpm output range.

The alternator is from a car and id like to wire it up to a marine engine how do i wire it to charge a battry


You will need to Wire up the + to the output terminal of the alternator - and the - to the chassis of the alternator.
Boats, typically, do not have grounding straps.

When my bass hits, my car lights flicker.


Is the problem much more noticeable when the car is at idle? Double check that Alternator output. 70 amps is not high output, and if the problem is especially noticeable at idle, it's probably due to the alternator putting out lower voltage( a common thing with alternators). Also, with that much draw from your sub amp, the wire from battery to alternator should be beefed up, as well as the ground wire from battery. You can make up your own cables by purchasing the wire to length and wire lugs at a local Welding shop, 4 gauge from alternator to battery is good. High output aftermarket Alternators shoot into the 200 amp range.
