SOURCE: No picture; dark screen. Red light turns to green

I would check output voltage of the power supply first to make sure that you do have DC 5v, 12v, and 24v. If you do then the problem can be in the inverter board. The inverter board also has a couple surface mounted fuses on it. You can check www.shopjimmy.com for parts.

Hi.

Unless there is a determined flashing pattern, the light switching from red to green, then back to red, indicatest simply that there is an internal fault; that the incorrect voltage has been detected, and that the TV has been forced to stand by to prevent further damage.

After you click several times the TV turnson: This is common. Depending on what component is damaged, the TV may overcome the problem once a determined circuit has fully discharged; when a circuit is fully charged and stabilized, or even erratically because of a bad soldering joint or wiring.

This kind of problem is commonly caused by PSU or inverter. This parts use big charge reservoirs (the capacitors) to store charge. When one of the capacitors is faulty, the other parts in the circuit can compensate for a certain time the problem, allowing startup. The problem will get worsening in time as components in circuit will go will start blowing soon. The result will be a TV staying in forced standby and not starting.
Parts must however be tested before replacement. Even if PSU is more common problem, there are more parts that may need testing. In this particular model SMPS must also be tested.
If power supply stages are OK, testing will follow on digital board, inverter and other parts.
Since the TV is occasionally starting, voltages may be OK. Testing will start at component level in this case.
Repair must be done by a trained technician.

If you need to contact a technician, or if you want to verify warranty status, please contact the RCA phone number listed in the user manual.

I have a RCA 32" Flat Screen TV that shut off and


Hi,


The sound was came from the clicking of the relay. This kind of symptoms is an indication of out-of-regulation condition on the power supply section. This is caused by faulty electrolytic capacitor. It will dropped the supply voltage and will trigger that kind of symptoms.


Faulty electrolytic capacitor mostly has a physical indication of fault like bulged/dome at the top and can be easily identified. See sample picture of faulty electrolytic capacitor below.

capacitor with bulged/dome at the top.


Check these parts on the power supply section. Once found, replaced it with same capacitance and working voltage which is printed on its body itself. Click this LINK for more info regarding electrolytic capacitor.


If you don't have necessary tools and test instrument and can't troubleshoot the unit yourself, I would advice you to look for a qualified TV Technician to isolate the faulty parts.


Hope I helped you.

Have a nice day!

Thanks for using Fixya.

Most likely you have the problem in the power supply. In most cases you can actually see small capacitors swollen . IF you replace these with new ones your problem will likely be solved. It does require soldering.

No picture, just a red blinking light


First make sure to hit the menu button on the TV's remote and if nothing is there then friend while the set is on turn a bright flashlight on and shine at angle into the set push the TV menu button if you can see a image then your back light is not working.
Cost backlights around 150.00 and power supplies around 100.00. Well this should help you friend.
