I need to change the transformer inside the power supply. can you tell the the output voltage?

If it is the transformer, it should be a DC output. Look where it connects, it will tell you what voltage you need. Use a volt meter to see if you are getting that from your "transformer". If so the amp in the speaker is probably blown, if not you need a new DC power supply with the correct voltage. If the replacement ma is higher that will not hurt, The information should also be on the "transformer".

it's encouragin! I got the same issue this night with my oe .. and here I don't see answers ...

My self sushil from india pl.find the details
yellow-blue is 3.2 VAC
red-white is 4.2 VAC.
Clock is well functioning without frequencies difference error. I think the clock is using crystal for pulses generator instead of AC power supply frequency.

you need to check the voltage output of your power supply section.This power supply supply is a switching type power supply.there is a chopper transformer in there.its supply is a dc voltage unlike any other transformer which is AC supplied on the primary..First step.
1.Using a multitester measure the primary supply it is a DC voltage around 220v - 110 VDC
2.Measure the secondary output.The out put is AC voltage the supply for the B+ going to plyback is 115vdc the second output is 12v run through a regulator and the regulator lower the voltage to 5vdc.this 5vdc supplies the system IC and the jungle IC.this ic process the switching of the plyback transformer and the plyback transformers output supplies the voltage of the whole system including your relay in the degaussing section....once the plyback is activated the tv will now turn on...

good luck!Hope i helped you..

please rate my help..god bless!

u can find voltage converter connectors......try using that....u can ask for travel adapters....hope u find them

Power supply will need to be changed

Output voltage on PS is -(negative)19 Vdc at center pin. 12 volts will work if you have the right size plug.

Hi.
It very unlikely the voltage went down. I think you should re measure what the voltage should be yes it 13 volt is after the bridge you wil get this with dual 6.5 volt ac from the transformer, they don't change voltage unless you have a short at the output, and if you did you will blow the transformer, is your reading from 2 wires or is it three wires, output, the center to the end should be 6.5 and end to end maybe 13.8.
I would need to see the schematic to know what voltage you should be getting.
I wouldn't look on a bat transformer but ether, bad bridge or wireing.

I hope this help's

What About Bob

Hi There,

The Hor Output transistor is connected to the Line Output Transformer. This transfromer provides a lot of voltages around your TV set but includes the very high voltage to the Picture tube...

These transformers are specially tuned to resonate at a certain frequency,
The Hor output transistor needs to match this frequency....so if the wiring inside the transformer is shorted by "just a bit" the picture will be visible but the transistor is struggling to match the transformer impedance,from the mismatched tuning...so the transistor draws more current from the power supply.. runs hot then burns out...

Usually manufacturers provide a Trip circuit that detects that an overload on the power supply is occuring and cuts the power to the Line output stage ...this is usually detected by a clicking sound within the power supply its called hiccuping.

If some one has altered the correct setting on the power trip circuit then the next thing that happens is the Transistor goes Blooooey like in your case.....

So to save you a lot of money replacing the output transistor
please replace the output transfromer as well next time...

But please... please... re-check the power supply trip circuit to save you a lot more expense in the future....
