SOURCE: 53UDX10B 53 in. Rear Projection "3D vision"

the convergence IC`s and associated resistors have to be replaced, do not repeatedly push magic focus or the alignment after the parts change out will take longer which of course means higher repair bill, good luck

Does the magic focus work on your set ?

If it doesn't you must replace the convergence Ic's with a kit that is available through your local parts distributor

You must replace all resistors in the kit
If you are not good at soldering and de- soldering have a local tv shop do it for you

Good luck

SOURCE: Hitachi 53" rear projection is losing its picture.

If you are not experiencing any shift in colors, it sounds like the power supply is failing since this will affect all three colors.

SOURCE: tv won't come on

If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

I have a 53" Hitachi Ultra-vision TV, it works well and I like it. The problem is that sometimes it turns white&black, and when I hit it little bet on the side it turns back on colors. Can someone help...


I reckon there is something loose inside, could be on one of the boards insdie. the unit will need to be opened and locked at to see what is the actual cause.

From ym pov only thing i can say is something is loose you going to need to hire a repair guy to fix it if you cannot.

PROBLEM WITH GETTING LOCAL hd CHANNELS


You need to have a set top box.

By law, as of March 1, 2007, almost all televisions should include a built-in tuner (called HDTV, digital, or ATSC tuners) that can receive high-definition programs over the air by simply connecting an antenna. Your HDTV doesn't have such a tuner, you'll need to connect an external tuner (or cable or satellite box) to watch high-definition programming. External over-the-air HDTV tuners currently cost at least $150.

Will not come on


Good Day, codysdad0331;
Before calling an Authorized Service Center, try unplugging TV from wall for 3 to 5 minutes plug TV back into A/C outlet (reset). If no fix call "ACS". Average cost for you TV is about $650.00 depending on shop, location; always get a written estimate. Good Luck, big IRISH.
