Question about RCA F35731MB 35" TV

1 Answer

My RCA F35731MB will not turn on. there was no other problems before this. its not the power button as I can hear the click when button pushed. I work on computers and laserjet printers and have worked on monitors so I know how to avoid being shocked and feel confident about replacing any part in tv. I just need to know where to look for power supply info and how to replace it.

Hello
It is very give you advice as you are aware of it. So do one thing. As far as the device is not turns on its power, the fault should be somewhere around the power supply system. Begin from AC mains chord itself. Check it for any break. If it is Ok, check whether supply is comming inside to your TV. Normally TVs have DPST type [Double Pole Single Throw] switches used for power switching. If any one of its poles not get correct contact inside, either phase or neutral will be cut. The click sound is not considered for its correct function. Check it also. It can be ckecked by measuring the voltage comes at rectifier points of your TVs power supply regulator section. If there is voltage, check the DC voltage across main filter capacitor. It must be some more than of your supply votage. I don't know the exact voltage you have as mains supply. Here in Idia, we have 220VAC 50Hz. At this supply voltage, DC voltage said above will measure more than 340VDC. Get a comparison with this when you check the voltage at the point mentioned above.
If it is also ok, there may be some fault in the oscillator section of the SMPS [Switched Mode Power Supply] section. There may be transistors or an Ic may be used to make oscillation to drive the switching transistor, which in turn drives the swiching transformer to get proper secondary low DC voltages needed to the circuit board. Check all the transitors. Of optocoupler is used check it also. Check its DC side control drive transistors.
Check all the zener diodes "off circut". ie take it out desoderd and check it with multimeter [preferably analogue type], set to 100K range. There should not be any leak at all. It is best to replace them.
Check all the resistors for its value marked, and all the transistors either for short or open.
Ok.

Power supply or high voltage supply problem---set well known for bad solder connections in and around the high voltage transformer---also known in early models for the high voltage splitter to be bad.

RCA D52w20 TV WON'T POWER UP


I had the same problem and it was the cp150. It cost me $2. Easy to change. I would look in the back and see if any of the capacitors are popped or bulging out on the top.

THE SOUND ON THIS MODEL WILL NOT WORK ( F35731MB )
ITS NOT THE MUTE ON THE REMOTE, ITS IN THE TV ITSELF.

The clicking repeatedly is the relay clicking on and off due to the power button being pushed in. You are having problems with the start up circuit. Probably minor but you would need a service manual to actually diagnose the problem . Let me know if you would like me to post a link where you can get the service manual

Tv PROBLEM


More than likely you have loose connections on the power supply board. Fixing the connections should take care of the problem.

T.V. DO NOT TURN


There could be a problem in the main power supply or perhaps the standby power supply. To me at a guess i would say there is most likely a bad capacitor in the standby power supply or there is a problem in the switch mode power supply. if you have no electronic troubleshooting skills, play it safe and take the set into a repair shop or replace it. Now a days, a 32" TV set can be had for under 200bucks. Good Luck

Flickering Picture?


Your set might have a high voltage leak and that is the noise you hear when is showing the screen problem or even maybe an arking too ,either one is related to the high voltage and it can be dangerous,if you are familiar with tv service you can try to see where is arking and replace the part with an exact replacement but if the set has a leak you will not see it and is not safe to be close to it,if you are not too familiar be safe and call for assistance from a servicer.
