    A link to the .pdf datasheet file is http://www.digchip.com/datasheets/parts/... Unfortunately any links on that site want to sell you thousands of the part. Use the application notes to check surrounding circuitry to make sure something else is not at fault. So you don't kill a new part when you put it in. Check ebay to maybe find the part as a single item, listings change daily, if you don't find it at first don't give up too easily.

The fuse inside the head keeps blowing when i turn power on, and Im getting continuity between the white & black from the transformer


Hi,
Looks like the main power IC is shorted!
Check the main power amp IC and replace it if there is a short between their pins!

Hope that helps you out!

My car Amp keeps blowing the main fuse, How to find the short?


Hello A4en1, hi, A short circuit need not be burned, the short usually are semiconductors such as ICs and transistors or diodes, I suggest you replace your IC power amplifier.

As you probably know the regulator also supplies power to the other ICs on the board. If the fuse keeps blowing that means that one of the parts drawing power is shorted. By looking the pin configuration up for each IC you can find which one is the + and which one is the- etc. The faulty IC will be showing voltages on the other pins where they shouldn't be. That is usually the defective part. You will also want to check parts that are related to or in the same circuit. The worse case scenario is that the main IC is shorted. Without the schematic its a long arduous troubleshooting procedure but it can be done and I just thought I would suggest it. I mean know pffence and just wanted to help somewhat.

Hi. Which model is it from? You can usually repair the power supplies rather than replace them.

Short Circut, blows fuses instantly.


OK usually the fuse goes because the Amp's IC's are drawing too much current thus the fuse blows... either this OR the Power Supply has gone Kaput. It is possible to replace the output IC's.. as it is to fix the PSU.. But it really is a shop job..

Fuse keeps blowing


NEVER EVER replace a fuse and think that va fuse will blow all by itself. The fuses are there to protect the set from catching on fire incase theres a short inside the set. Now in some cases an intermittant short can work after you replace the fuse but if its burnt black or brownish, theres a short inside the set in one of the circuits. always use a 100 watt light bulb across a blown fuse if your not sure if there is a short. if there is, the light will absorb the short and glow bright. if there is no short the bulb will glow bright , then go down very dim. you could have a main power supply problem, such as shorted bridge rectifyers,shorted main b+ capacitor, Hot could be shorted, or the Vertical or audio output IC could be shorted

My tv power does not come on


This set uses a switching power supply. Usually when there is a short on the output side of the switching transformer the supply will just shut down and refuse to operate but normally will not blow a fuse. If the fuse blows suspect a problem with something shorted on the input side of the switching transformer such as I801 regulator IC, diode bridge D801,or other shorted component. Perhaps someone else could tell both of us any other part that could cause the regulator to blow and should also be replaced to prevent regulator failure in the future.
