Check power supply first and if brand correct check with Sanyo with the model number.

TV will not turn on. Clicking noise heard from inside.


These sets use what is called a "switch mode" power supply. In order for them to work there is a capacitor that "kick" starts the process. If that cap goes bad, the power supply will not start up. Also, there are other caps inside that maintain the oscillation required for the power supply to work. There are 2 options for you here.

1) Replace the entire power supply module.
2) Repair the existing one.

Sicne these types of power supplies are not the easies to diagnose or repair, I would suggest that you replace the power supply module. That should resolve the problem.

Please note that there are other causes of the reported problem, but hte power module becoming defective is the most common.

Replacing STK Modules in a Panasonic Rear Projection HDTV


Hi there.

If you look up the datasheets for the 392 series, you'd find more differences than power and voltage ratings... Using a similar IC (even if it is the same series) may make it difficult, if not impossible, to converge. It's recommended to change the 2 ICs as a matched pair. Since one already is failing or failed, the other probably isn't too far away.

The resistors mentioned are to bias each output stage for proper deflection and must be within tolerance. They're precision blue flameproofs, so if anything really heated up from a bad IC you'd easily catch any browning / burning. Red is IC7001, blue IC7002, and green is split between the two ICs.

Tha advantage getting a factory supplied or authorized distributor part is you know the LOT NUMBER has been approved by the manufacturer. Generics or unusually cheap originals are often rejects from the manufacturer as being out of tolerance.

The originals are only $29 each directly from Panasonic. Why go through all the effort tearing the thing apart twice to save $30?

Good luck, Mark

RCA P61960 projection screen. no picture, no sound. tries but shuts off.


It will depend on the Chassis number you have but it sounds like a bad Deflection module or a bad Convergence power supply module. The Convergence Power supply module is on the left looking from the back mounted above the deflection module. On newer models the picture tubes can short and put these sets into shut down mode ( Three Trys). Start by unplugging the CRT modules off the neck of the tubes one at a time. If it doesn't come on you have eliminated the tubes. There will be a Red and Black set of wires from the deflection module to the convergence power supply module. Unplug it. If it fires up then it's the convergence power supply module. If not it will probably be the deflection module. The flayback transformer is a common problem along with several bad caps towards the front of the board. Let me know if this fixes it.

My sanyo tv was hit by a power surge.now it dosnt turn on. i have a 27 inch sanyo tv


You have a power supply issue on the main board of your set. This is not an easy fix for a home owner, Your best bet is to call a service shop and get a price quote. Tearing into tv's is very dangerous! High voltage is present even when unplugged! Good luck!

Bad power supply q301,q302 shorted


I'm going to guess that you have a Sony set based upon the circuit designations that you listed. If that is so, you really don't need the entire module. You will need to replace the transistors and a resistor. Possibly a cap or two will be required as well. Please post the model number and further details shall be provided.

Thanks,
Dan

Toshiba 56PW8 rear projection - lost sound and picture after powercut


The convergence amps in those units consist of two Sanyo STK392-110 Ic's that get hot enough to fry eggs.. If your storm flexed voltages enough it could have easily shorted the amps and/or take either of two pico fuses in the 24v supply line to the amps... If you're not too tech savy this is one for a reliable shop and not and expensive fix. Two Sanyo Ics and a couple pico fuses should be more than $50.00 dollars and a couple hours of labor to put them in... While they're at it have them check the caps in the hyper module and for any ring cracks in the deflection circuit...

No power with remote or manual power switch


Your convergence module is probably bad. It is a plug in module, so labor would be lower if the convergence settings are still good. The bill would be about $300.00 If not, the labor for convergence would add to the bill. If the whole job needed full convergence the cost would be about $500 to $600.
