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

    Starting problem Dead TV. RCA 32F530T, chassis ATC113CD4. I Replace flyback # 257807 along with the H-O/P XSTR (2SC5148).
    > Problem fix. Everything work fine, except i have hatching or tearing lines at one or two places on the screen depending on the white level (contrast), always in half screen area on the top. Same symptom with video and RF input.
    >I replace the flyback 3 times with different part # (not original RCA flyback) and suppliers, 257807, 257805 and ACME-2632 (replacement for RCA #261163). Still have exactly the same problem with 2 tv set. I checked parts in the horizontal and vertical circuit, DC supply, everything looks good.



    RCA 32F530T TV year 2004 (not 32F531T).
    Original RCA flyback NLA. Use original Horiz output transistor Toshiba 2sc5148.
    If i lower the vertical height, tearing lines disappear. No error code in service mode.

    Any suggestion? Bulletin note?
    Someone saw that before?
    Thanks

Humming, static noise when answering message is playing, RCA 25425


First thoughts are is the device near to a wall socket power supply?
Non "Switch mode" power supplies use transformers and these give off a radiated 50/60Hz hum which can be picked up by devices with amplifiers such as answering machines and phones etc. Try moving the answering machine to a new location where there are no power supplies nearby and see if that makes a difference? If it does you have a couple of choices, leave the machine where it is or move the power supply to another wall socket further from the answering machine.

Replace power supply


It should work provided the components do not draw more than 400W.
If the wattage is exceeded these switch mode power supplies usually automatically shut down.
I recommend you install a switch mode power supply over the 420W rating.

No power from transformer


If the switch mode power supply does not power up then it maybe be faulty.
First check the power button wires from the front panel to the motherboard is seated correctly on the motherboard.
If it still does not boot up then replace the switch mode power supply, make sure the new switch mode power supply has the same or higher wattage rating.

When i switch on there is a buzzing noise and


Sounds like an issue in your power supply. Try a good second hand supply or, if you have to purchase a new one, get a new case with a supply and install the guts of your PC into that as Dell power supplies are very expensive (if they are available at all for your model). Swapping everything into a new case is a pain I know but it may be a lot cheaper then a dell supply. You can also have your supply tested by a professional. Don't be tempted to open the supply and fix it your self.. Switchmode supplies are more then happy to provide all the power needed to turn you into a sticky mass on the floor!!! and the surge capacitors can hold a formidable charge for several hours which really stings when it bites you !!!

2003 gmc mirrors do not fold in


The power mirrors are controlled by a module (computer) DDM - drivers door module an the PDM - passenger door module .
Folding Mirror System
Folding Mirror System Controls
The folding mirror system requires signals from 2 separate switches. The mirror select switch must be in the neutral/fold position and the mirror direction switch must be activated to the left/extend or right/retract positions. Both switches are integrated into the DDM and provide direct signals.
Folding Mirror System Operation
Upon receipt of the required switch inputs the DDM will supply battery voltage and ground to the mirror fold motor control circuits to perform the requested extend or retract function. The DDM will also send a class 2 message to the PDM indicating the requested function. The PDM will supply battery voltage and ground to the mirror fold motor control circuits to perform the requested extend or retract function.

Power Mirror System
Power Mirror System Components
The power mirror system consists of the following components:
• The driver door module--Class 2 module with integrated switches and requires programming when replaced
• The passenger door module--Class 2 module with integrated switches, requires programming when replaced and also contains the RFA receiver
• The power mirror direction switch--Integrated into DDM and is a 4-position momentary switch that provides a signal input to the DDM for up, down, left/extend and right/retract with a mirror switch activation
• The mirror select switch--Integrated into DDM and is a 3-position switch that allows the operator to select the left or right mirror and also a neutral/fold position
• The left outside power mirror--Contains both the vertical and horizontal mirror motors and is serviced as a complete mirror assembly
• The right outside power mirror--Contains both the vertical and horizontal mirror motors and is serviced as a complete mirror assembly
• The body control module--Class 2 module that requires programming when replaced, serves as the power mode master and is the main message handler
• The DDM 10A fuse--Located in the I/P fuse block and is hot at all times
• The PDM 10A fuse--Located in the I/P fuse block and is hot at all times
• The memory switch, if equipped with memory mirrors--Supplied power by the DDM and provides a voltage signal to the DDM upon a switch activation
• The horizontal and vertical position sensors, if equipped with memory mirrors--Supplied a 5-volt and low reference by the DDM/PDM and provide a variable voltage signal to the DDM/PDM that is proportional to mirror position
• The park neutral position switch, if equipped with memory mirrors--Provides transmission gear selection information to the PCM and is used for memory recall and mirror tilt in reverse functions
• The powertrain control module, if equipped with memory mirrors--Class 2 module that requires programming when replaced and provides Class 2 message indicating transmission gear selection
• The driver information center (DIC), if equipped with memory mirrors--Part of the instrument cluster which is a Class 2 module that requires programming when replaced and is used to personalize the memory recall and mirror tilt in reverse functions
• Fold motor in each of the outside mirrors, if equipped with power fold mirrors--Provides extend and retract movements of the mirror and is serviced as a complete mirror assembly
Each of the outside power mirrors contains 2 reversible motors to provide horizontal and vertical movement of the mirror glass. The vertical motor operates the up and down directions and the horizontal motor operates the left and right directions. If equipped with power folding mirrors, each outside power mirror will contain a reversible fold motor to operate the extend and retract functions. Each of the mirror motors are circuit breaker protected.
DTC B1722
The driver door module (DDM) and passenger door module (PDM) switch the mirror fold motor control circuits to battery voltage and ground in response to mirror extend or retract command.

Rca 42 in lcd it shuts off 5 sec after being turned on


This could be a power supply problem, these tv's use a series of switching mode power supplies usually mounted in the same circuit board , the light flashing is an indicator that this is the problem, but these boards are expensive so you may want to get the tv looked at before anything else. You do not mention if the sound remains in your description of the symptom, but just in case it does then a back light inverter could be at fault. hope this helps. thanks for leaving you feed back.

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.
