This TV has only 3 boards - power supply, inverter, and main/controller boards. Most likely it is the inverter board - i.e. no backlight. If you still have sound, the power supply is on,

I can get a picture , but no sound on the TV . What am I doing wrong?


Many RCA TV sound problems are caused by SAP function being activated by TV station equipment that converts Analog TV signals to HD signals. Accidental pressing of the wrong buttons on your remote can also cause this problem.

The incorrect conversions causes the Audio settings to be changed from Stereo to SAP by the received signal.

Solution is to go to Audio set-up in customer menu and change settings from SAP to Stereo. If you find that settings are wrong, change them to "Stereo". Do channel scan if you are using the TV tuner/remote to select channels. Turn off the TV and unplug for 60 seconds. Check the settings again and reset if required.

This problem may re-occur when you select the VHF channel, satellite channel or cable box channel that is causing the problem. It is not a TV fault that can be repaired. The problem is caused by the incorrect incoming signal.

SAP is Second Audio Program, used for second language transmissions.

Second cause may be that the speakers have been turned off in the audio set-up menu.

Samsung T.V. goes on for 30 seconds then no picture


If this is a flat panel LCD tv, this is a sure sign that the panel itself is bad. I have seen this before. Tv comes on works fine then within 5 minutes goes blank.

TV turned off itself


Can you still turn it on?
If so, does it stay on with sound?

If the sound is ok and the picture is blue (even when changing channels, inputs, etc.) the lamp may have gone out.

Can you see the TV menu when you press the menu button on the remote or TV?

This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source.

Daytek DT3220 power button flashes green 4 (5) times, no picture


The power supply voltages might look good on an oscilliscope or using a DC meter, but that doesn't really tell you if the supply is good.

Your TV has an unusual symptom, however 99% of the problems on these TVs are caused by the power supply. I have had 3220s that won't power on, the remote or controls on the TV won't work, or the unit blanks out and all sorts of other odd problems. The power supply can test fine, but if you substitute it the TV will work fine.
Sorry to say you're up a creek. The good news is that just about any 5,12,24V power supply for a 32:" TV will work if you are comfortable rewiring the connectors. I have done this a few times and rescued the TVs from an early grave (I'm actually just about to start on another one now). The pinout is written on the board, and make sure the power supply you want to use also has the pinouts marked on the board.
