Question about Hitachi 43FDX15B 43" Rear Projection Television

No power The red led light is on and you can hear a faint click if you hit the power button but no picture, no sound and no input appear. TV has worked fine and then just stopped. I unplugged it and gave it the rest for a reset but to no avail. Where do I go next? I am handy and willing to attempt any repair. Just need to know what to look for. thanks Dr. J. A. Lewis

Well Dr. Hitachi has a sequence of L.E.D lights in back of set that lights up in accordance to what is wrong with set. there are about 8. so you need to first get someone to turn on and while looking notice which lights up first and goes out first. This tell the tech what is wrong with set. From my experience with Hitachi, I have replaced many Convergence amps which are the big STK's392-*** or something close to this depending on the set. But it most of the time gives some kind of indication before going out. Like color problems not matching up. Red, Blue or Green out of line, mostly on corners of set. If no color problems then next would be sound problems, and vertical problems. Either problem will give a no High Voltage problem like yours. Also it has little pica fuses, sometimes yellow in color. These can be open also. There are many areas to check but if you are willing you can find the problem. Remember to be safe at checking anything with set plugged in. Turn off first. Hope this helps!

the circut that detects the bulb has been also failing in these sets
and the conversion chip that controls the picture , and the transformers are not putting out the full power they are supposed to.
this set will need to be tested to determine the exact cause or causes

Samsung TV (model UN40H6203AF) 40" LED. No picture, have sound. Flashlight test can see faint menu screen. Have replaced power supply & main boards to this point. Ideas as to what to do next?

Hi Terry,

If you can see the faint picture in flash light means the power supply and the main board is working. The real culprit is the backlight. Even one bad LED in the backlight will switch off the whole array. To repair this fault the panel has to be opened and the defective LED or LEDs are to be replaced.

This is a complicated, delicate and risky job and must be attempted by an expert only. You may end up damaging the screen permanently if you have not done it before and try to DIY.

No picture or sound

Remove the rear panel. With the TV on you should see a red LED near the center of the PCB. There should also be 5 green leds, 3 to the left a 2 behind. If there is no red leds, check the fuses. If there are no green leds or maybe 1 or 2, disconect PSD5. It's a connector on the left side of the power board that connects to the audio board. It's the 3rd on fro the back. It's labled. With that disconected, turn on the set and look for the green leds. If all 5 light, the power supply is OK and you have a problem beyond that. If they don't all light you have a bad power supply.

TV won't come on!

Most likely, this is a problem with the convergence board. The convergence amps (STK392-040 x 2)are internally shorted. These can be replaced or the whole convergence board can be replaced. It's cheaper to replace the amps, but more convienent to replace the board (especially for the less electronically inclined!! :) Also, this could be from a leaking CRT. In CRT projection televisions, the red, green, and blue tube are filled with coolent (glycol). These 42" models are very bad about the tubes leaking (Akai and Samsung models)and are infamous for destroying the CRT driver board connected to the bottom of each tube. When this happens, the protection circuit kicks in and will not let the television start up. *PLEASE, FOR YOUR OWN SAKE, DO NOT FOLLOW THESE NEXT STEPS IF YOU HAVE NO UNDERSTANDING OF ELECTRONIC EQUIPMENT!!!! There are four screws and three snap clips that hold the bottom on. UNPLUG THE TELEVISION, remove the screws and pull bottom outward to remove. The bottoms of the three tubes should be visible. DON'T TOUCH THEM!! Now look under each tube. If one is leaking, there will be a wet spot (or sometimes a puddle!) underneath the tube. This will have to be serviced by a TV tech. Hope this helps...
