Question about Hitachi 50V500 50 in. HD-Ready LCD Television

1 Answer

Great...Thanks big IRISH, Wow...thanks for getting to my problem and trying to help me! I just want to make sure that I understand what your saying here...basically that it "could" be that the ballast is dead? Is that correct? I do see a connector facing down on the ballast, it is a 5 pin connector, with the (black) leads coming out of it towards the left side, correct? I am sorry, but I do not follow what you said about determining the Spark Gap Process. Since the bulb is practically brand new, I can almost certainly rule that out. But when you try to turn on the set...the bulb does turn on for a moment. Would that happen even if the ballast was dead? How do I verify, or test this? Thank you!!!! egear00

Good Day, egear00;
This chart shows were voltages are on the ballast. If you the voltages then suspect the ballast, if no voltage suspect the the power source.
Good Luck, big IRISH.

Remote


Good Day;
After changing batteries and it still does not work with THE TV's remote? One of two things; you have bad remote or IR detector on TV is Defective. MAKE SURE you press the "TV" button on remote first, then try again, esp if sound works. The remote may be an universal type.
Good Luck, big IRISH.

Hi I Have a samsung TXK3679 36" TV it was working great until today I have no picture only sound.Im looking to find a service manual to see if I can find the problem. Thanks


Good Day, seadooerxp;
Before you look for a service manual, try resetting the TV by unplugging it by the A/C cord. Unplug for 3 to 5 minutes then plug back into A/C outlet. Try Source Box also. If no fix re summit complete Model Number and Version.

Good Luck, big IRISH.

Good Day, hdj2269808;
So, you have a RCA TV that does not come on and you hear three thumps. What you are hearing is the TV trying to turn on, the TV will attempt do this . If you are technical please give me complete Model Number, if not please call an Authorized Service Center and have them come out and give you an estimate before repairs begin.

Let me know, big IRISH.

Getting close...thanks


egear00; OK, you have voltage, check this:
1. Filters make sure both are clean
2. Check the power supply and check for bad CAP's
3. Check the lamp sensor.

Have a hitachi 55vg825, gets power but will not turn on


Good Day, titanlife;

So far you have done a great job!

But now what is wrong? I would suspect the power supply, ballast, but the best advice I can give you is that you contact an authorized service center and have come to your home and (make sure) give an estimate.

Sorry, I wasn't more helpful.

Good Luck, big IRISH.

Mitsubishi power board pcb post


Good day, steve sc;

The DM board is normanlly on the left side TV looking from the back. It has a shield around it, remove. The caps are big and black, they look the replacements(only ones on board). Here's what says about this issue:

If the LED keeps blinking with connector FC removed suspect a problem on the DM PCB (part # 934C116002). (LED does not stop blinking after plug in) On the DM
Good Luck, big IRISH. ps hope this helpful!
PCB (part # 934C116002) check C81A2, C81A3, C81B3 and C81B4 (1000 UFD, 16V, 105C), if any are bad, replace all of them with part # 181P734030 (680 uFD, 16V, 105C). (LED does not stop blinking after plug in) On the FMT PCB (part # 930B924002) check C8F19, C8F21, C8F22, and C8F27 (16V 1000 UFD 105C), if any are bad, replace all of them with part # 181P734030 (680 uFD, 16V, 105C).
It is not an easy job, it will take some time but since you have it apart there is another problem that will accure so might as well do this too:
Tile or block pattern with no video or OSD. Check D8F00 and D8F01 part # 264P828010, also check C8F26 and C8F29 part # 141P148000 (1 uFD, 25 V) on the FMT PCB (part # 930B924002).
All the parts have location numbers like C8F29 that will tell you what and where these parts are.
Good luck, big IRISH.
