Question about RCA 32F530T 32" TV

1 Answer

Switch mode power supply not switching and buzzing when powered up.

I have a two fold question; firstly where can I get schematics for this RCA and secondly is the unit worth fixing as the switch mode PSU appears to be problematic and it could be a multitude of items that have broken down - is this a common fault?


Many thanks

Power button flashing but tv wont come on

The switch mode supply is working and the microprocessor is allowing the power to switch on but with errors.
The back panel must be removed so that you can start to check if the mainboard is receiving the +B voltage required for the switch on.
Check the 130 volt to the output ( LOT) if it is absent check if the driver is short or if hte LOT is short.
Remove the main lead and if the voltage comes up the LOT is faulty.
Order and replace

RCA Model# 32v434t,Watching and just went blank,no sound

it's called 'standby mode', so people don't have wait 30 or so seconds of their lives waiting for garbage to come up on their screens. fast junk food-fast junk t-v. whataya' goin' to do? get a switched power bar, and turn it off when you're done watching. that standbye mode is what some consider 'vampire drain'- it sucks power and keeps your meter turning outside. same with 'wall warts'- power supplies for cell phone chargers, battery chargers, any re-charger power supply. they're gradually mandating 'switching power supplies'- they're a bit more expensive to manufacture-but when there's no device hooked to them, they switch off, and draw no power! if you have any 'wall warts', put your hand on them when they aren't attached to any chargeable device- you feel heat? they're wasting electricity! it really adds up, nationwide!!
enough of my rambling! you have the right instincts!

My tv wont turn on when i push the power button it ticks??? what coud be worng

if your tv is not powering on, firstly check the switch contacts, rectifier diodes, power trsnsistor, fusible resistors and zener diodes. all these components are at power supply section.

make sure that a HT voltage of 90-115v, shows at the line transister near the line transformer.

note-----a tone be head on the supply.

Set is dead

Replace the Horizontal Output transistor and High-Voltage Transformer.
Set will come on, if it goes back off,solder around the switch mode power supply even if it looks good.

High pitch buzzing.

Hi there
Let's make ur problem a bit clear. "white lines" how? where?
meaning retrace lines with full raster or a single vertical line?
buzzing sound? without even turning the power switch of the TV to "ON" or when u just plug the power cord?
I'll check for schema, mean while can u tell me where the resistor leads to? is it a fusible resistor? if so , to which area the resistor suppliers power?

Buzzing noise with no picture or sound.

The power supply is telling you that it has a short. I think you have a bad high voltage transformer in the horizontal deflection circuit. I've repaired several RCA's with this very same problem. The newer RCA's are vert prone to high voltage transformer failure ! Stargazer

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

RCA Model F36450 Chassis ATC113CA1 won't power up

No sir it probably isent a power supply problem as in these sets it wouldnt act like that. First thingm to check since you say your a service tech, is in the horizontal output check and see if the horiz. output transistors shorted. If its not then check a small coil off the base of the horizontal output transistor. its really the base drive coil so take it out and scrap off the ends BOTH ENDS and reinsert and also resolder the horizontal driver transformer. This may or may not fix your problem But if it dosent order if you think ther sets wrth it the flyback transformer as this is a big problem in these sets if the for mentioned things did do the trick. follow the kit instructions that come with the flyback transformer!! Dont take any short cuts. Make sure you do take out the horizontal output transitor or at least unsolder all the leads when tesating it for a short. Good luck
