Question about Hitachi 36UX59B 36" TV

1 Answer

Intermittant white line with subsequent shut down

I have had this set for quite a few years without incident. Recently, with no discernable periodicity; a white horizontal line with no picture pops up(black screen above and below the horizontal line in the middel of screen) in the middle of the screen and after a second or so tv shuts down. If we unplug the set and let it sit for a couple of minutes and then plug it back in--it will sense input from satellite receiver and turn back on. Sometimes it shuts off 3 or more times in a 30 minute period and sometimes it will go all day with no problems/

White line in center..sound iis fine


Most common are soldering problems on the vertical deflection IC's.
If this line is quite bright: shut down the set, it might damage the picture tube permanently. Resolder all pcb connections under the vertical defl. part. With a magnifier you can see "craters" around the footprints. Where is the vert. deflection. ? Mostly an integrated circuit
on a vetically mounted heatsink . Typnumber: mostly something TDA53xx like. Gently knocking with a screwdriver and observing the screen might lead you to it's location if you're not familiar with TV's.
Watch out: lethal voltages !

42 inch Samsung DLP TV shuts off by itself. I can turn it back on and sometimes it stays on and other times shuts off within seconds. Some days it stays on all day without a problem. Other days it shuts...


I bypassed the safety switch (it was bad) and vacuumed and blew out all of the dust. So far with this set, 3 years old, I have replaced the bulb twice,it exploded both times, and the color wheel which also exploded! We love the picture but the next time it goes out, it goes out to the trash and I will purchase a top of the line LED/LCD set. No moving parts!!! Samsung designed and manufactured a whole bunch of lemon sets and will not admit it. I have found several hundred complaints about their DLP sets and only a few on other brands.

Intermittent collapse or rolling of TV picture

Panasonic CT-32G6E Intermittent single horizontal line


I would suggest to locate a part that looks like the one on this link and re solder all the pins, also check for any high power resistor nearby the IC295890 and put some fresh solder.
Let me know if you need further assistance.

TV shuts off and red standby/timer lights blinks red until I power the set off. When it shuts down it does so with a very loud snap. When I turn it back on the screen is blue and has light blue...


The most common cause for what you are seeing is a shorted gun in the picture tube. When 2 elements (heater and cathode) of one of the guns inside the neck of the picture tube touch, that gun goes full on and overloads the flyback (high voltage) transformer. If it is in the blue gun, the screen will go bright blue with light blue "retrace" lines in it. The computer senses the overload and shuts the set off. At 2 years old the tech most likely tried removing the short by arcing between the elements. This works sometimes but the short often comes back a few months later. Another attempt at removing the short could be tried, and it might work this time, but it may or may not work for long. The ony other solution is to replace the picture tube but that would cost much more than the set is worth. A qualified tech will be able to tell you if this is the problem in your set.

White Screen w/ White Lines, Sound On, Turns off after 2 or 3 secs.


Hi If you mean thin white lines, this is is an indication of a problem in the Horizontal Drive ckt. most likely the Damper Diode has opened or shorted, this would cause the visual symptom and then the set would shut down, unfortunately this is a problem best left to a qualified technician to repair, hope this helps.

56 rCA SHUTTING DOWN INTERMITTENTLY


This model has a history of being plaged with bad solder connections, and that may be your problem still today. If your state has "lemon laws" you might want to pursue that venue if contacting RCA directly doesn't produce results. RCA's have been my bread and butter for at least the last 12 or so years in the service business but I would not buy one today for myself.

Picture intermittently drops out.. other problems


Tv pricing has come down quit a bit these days and like the typical computor printers the ink cost more. In your case the parts will cost you a lot. With all the problems discribed "buy New" and get yourself up to date with that of what you want a Tv to do for you.
