My exact same problem turned out to be the cable box not the TV. Try unplugging cable box for 5 minutes then power up! Solved my problem!

SOURCE: rca 32 screen turns on but stays black

Theres no start-up signal being encoded, this means the interface board has an offset capacitive value. You need to test and measure the capacitors and npn/pnp transistors, along finding some open diodes too on the main board (interface). You have to test the capacitors under their operating voltage also to see at which point their breaking down. The problem is a 'load' condition on the main board. You can repair the board if your savy and you have test equipment or you can just replace the board. If you want to replace it e-mail me and I'll help you out....

Recommend opening it up and looking at the power board and see if there are any visible Bulged or leaking capacitors.
Bad caps are a major source of computer and LCD no post problems.
If you find em, then just find replacements with the same uF and voltage and solder them out/in.

Thanks in advance for choosing Fixya for assistance.

I would like to make a clarification request , before I present my possible solution to

your problem,


Does it happen on all TV inputs ? or just on the tuner?


Have you tried connecting the TV audio out to your AV Receiver or similar just

for initial troubleshooting?


If it happens to produce sound on your AV receiver , then Congrats...


you have just troubleshooted a large percentage on electronic circuits

inside the TV ( even without opening it up ).


I can post further , while I await for your answer , to resolve the problem

you are having and post if you can further DIY ( inside the unit )

You have answered your own question, someone needs to open it and find a loose plug or broken solder connection--if it reacts to being tapped on that is the issue- a physical problem inside.

43FDX15B No picture, Power light stays on


Just a thought, but check all of the pico fuses for a blown fuse. The pico fuses look like a small yellow resistor. Some Hitachi's are famous for having a blown hi-volt ceramic capacitor and a blown pico fuse.
I think the red led on is a short protect indicator, but I could be mistaken.

Monitor Not Showing A Picture. Light flashes Yellow and Green.


use the onboard graphics instead of a seperate graphics card (if installed) to test the screen.if it still doesn't work then unplug your monitor from the mains supply and plug in again to reset it. i doubt it's your monitor that is the problem though. but look on the back of your pc for another connection for your screen. the onboard graphics connection is normally vertical near your ethernet port and mouse and keyboard inputs.

please rate me and give me a fixya! if it helped.

Clicking sound is power relay engaging. If all systems are not functioning properly, unit will shut down to prevent further damage and/or fire hazard

No picture no sound


First check to see if you have any voltage at test points with a digital meter.
You may need a repair manual for this.
Since you hear some noise your main fuse is ok.
Try checking this tp voltages first.
BE CAREFUL, wear gloves
