OK, the volt reg showed up yest finally. I installed it, now the fuse does not blow when plugged in. I don't get any reaction from the tv when plugging in or when pressing the on button. It seems it does pull a load when you do plug it in for a brief moment. The tansformer near the regulator is a
bck 3532 36-TRF198 AX1. The transformer next to where the power cord is
36-LIF010-XX0. I have no diagrams to show what the voltage output should be to test. Any ideas?

Re: Disney TV prob you helped me with.
I could not find anything schematic for your TV.
I would suggest to check the horizontal transistor, if the transistor is OK; check the voltage at the collector. NOTE: be very careful when measuring this voltage, you should get about 130 VDC.
If that voltage is present, you might have a defective flyback transformer.

it has a varistor it is the protection of your tv against high voltage if over voltage is apply it will blow following the fuse. varistor is connected parallel to the ac supply replace it but dont forget to replace the fuse replace it to.
I have a Disney cars tv with built in dvd player and after 2 months it stopped working. The power will not turn on, the light just flashes once and then goes off. I have tried replacing the fuses and it did not work, could you please help me.
ok I'm looking at the owners manual and it says that if you tv is plugged in to a higher voltage outlet in my turn its self off as a fire safty switch. So check to see if the plug in is a 210 outlet if so thats your problem otherwise it doesnt show anything else about it turning off hope that helps!
I will say that this part is shorted if it measures continuity on all the leads regardless on how you tested.
Was this mosfet nearby the power supply circuitry?
You can also check the horizontal output transistor that is mounted on a heatsink near the flyback transformer.
Ok I know I just made a comment but guess what... heres the solution!!!!!!! I was sooo mad that I went and started playing with the cables and got it working. You have to plug in white to white, yellow to green and red to blue on the back of the DVD player and match up the colors on the back of the tv. And it plays in color!! Hope this works for you too!
whenever fuse blows every time it is the indication of short circuit in tv.
so please do not put fuse unless you know the cause of blowing fuse.
these are the reasons of blowing fuse.
1 main filter cap.short.
2 rectifier diode short.
3 swithing transistor short
4 horizontal output transistor short
5 caps & diodes connected to flyback transformer short.
6 print short.
7 at last if every thing ok then flyback transformer defective.
hope this will help.
if you are not a tech person call skilled tech to fix it.
Could it be in the HV circuit?
first you isolate h/output section from power supply.
make power supply output ok.
check h/output section for short circuit
1 print short near eht
2 diodes or cap.near eht
3 yoke H winding just by removing connector
4 EHT transformer
There is no reset button on these new sets,your set has complete power problem since you have no lights no clicks,this might have happen because of lightning or power surge,either one creates a lot of damage,if you are familiar with tv service you can check the main fuse,he should be close to where the power cord comes in,if you find the fuse blown it needs to be replaced with an exact replacement for AMPS rating and VOLTS rating as well as size,if the fuse is blown black we might have more problems ahead in the circuit and it will blow up again as sonn as you plug the tv back in,if it blows again it will need a more involved repair,the problem could be in the primary side of the power supply,if you are not too familiar you should seek the help of a servicer a least for an estimate but if you suspect power surge or lighting damage dont invest any more on this set and get a new one.
