Hitachi 43GX10B power issue

Hi my tv will not power on AT ALL. There is power hitting the boardthat the plug connects to but all fuses are good. Anything else youcould think of or processes that you want me to take? I work on laptopmotherboards, and I thought this would be no problem but I am in a darkroom with no light... HELP!

Tv wont turn on


Check the ff:
1. Power plug - for open internal wire due to frequent bending,pulling.
2. Try to power by remote - if power up by remote then you have a faulty tack switch.
3. Replace Internal Fuse - sometimes because of power surge the fuse fail. However if the fuse blew again this is an indication of shorts.
Next step is not Diy because of the ff reason
3. Voltage regulator - might be open or shorted.
4. H-out transistor - shorted
5. Open fusible resistor in line with the B+.
6.Dry joints

Thanks for using fixya.

Hitachi 43in. projection tv model# 43GX10B 2002


The color has gone crazy on you because your convergence IC's have gone bad.
These operate at a very high temp, and usually only last 4-5 years. 
If you remove the back of the set, you will want to look for the BIGGEST heatsink in there, on that heatsink, you will see 2 lage IC's , probably STK392-110, or STK392-150's you can go on ebay to order the new ones, but MAKE SURE they are Genuine SANYO IC's and not counterfiet cheapies. the cheap ones may only last 2 months..
You will also need some "Heat transfer paste" - you can pick this up at radio shack.
Once you remove the old IC's, test all the large resistors near them.. pull one side of the resistor out of the board so you can check it out of circuit. they will usually have the value in Ohms, printed directly on the resistor, but you may have to use the resistor color code to find out what value they are....However, usually if there is any damage, the resistor will look like it has been HOT or fried. replace the IC's and any bad resistors, and you should be good to go.
If after replacing the IC's and any defective resistors, the convergence is still bad, make sure to use a multimeter to check ALL fuses on the boards, --- sometimes when the IC's go, they will take out a fuse to the convergence power supply. If you find any bad fuses, replace them accordingly!
Hope that helps!

if the tv is completely dead, your first step is to check the fuses in the power supply.but if you get the standby light, and nothing happens when you hit the power button, you need to call the repairman


good luck

Hitachi 43GX10B 43 in. Rear Projection TV has sound, but no picture


Is the Lamp ok? Go to the rear of the set and turn on the set with your remote while looking at the vent slats. If you can see a bright light through the vent slats then your Lamp is working. If the lamp is on and you have sound and no pix, then the Digital bd is in what we call "Video Mute" and will have to be replaced. Also make sure that the Lamp Door is installed and the screws are tight
also check to ensure the following.....
1. re-seating the DVI cable on both sides
2. Check to be sure the lamp door sensor is closing (that is not your issue but i thought i would post the complete answer)
3. Check colorwheel is spinning up (should be a low hum, and not sound like a fan)
*** it is very possible it is a failed colorwheel, but the set should go into shutdown, so it is probably not the issue.
4. If the set has sound but no picture replace DMD board....


If the set is working and then just stops working best bet is the DMD ( i would not replace just the dmd it is cheaper in most cases and much easier to replace the lightengine) but if the set just is not working and just failed and is now always not working best bet is the digital board.

If you have an osciloscope you can measure the video signal from the Digital board and see if it is present with the no picture, if it is then it is a bad DMD but if the video signal disappears of then you have a failed Digital board. You can not us a computer USB scope, they can not read most of the data from the digital board since they use multiple scan rates and wont trigger on them for some reason, a old school scope works best i have found, or one of those new LCD scopes that have an auto trigger work well i have found that it is all i use anymore.

you can find a service manual with schematics at a very cheap price at ebay......

If you hear the unit comming on and theres no sound or Picture, then theres a fault in the horizontal sweep/HI Voltage circuit. This should not be fooled with unless you know the safty issues with HI voltage as theres voltage in these sets even after they are unplgged for a while. Good Luck
