Question about Hitachi 50UX58B 50" Rear Projection Television

1 Answer

Hitachi ultravision 5oux58

I could not find 5oux58 so i thought this would be close. My tv made a pop sound and then i smelled something smoking and i unplugged it. We were going to look and see if we could see what had burned after we took the back panel off. We plugged it in and a few of the green lights in the back of the tv came on and went off. When we tried turning it on nothing happened, no lights on front or in the back. We are trying to see what needs to be replaced or if it is worth it. My email is
Thank you, Holly CarverĀ  my will not turn on. the red power lite comes on for split second and than go out. I have done the reset, but nothing happen.

TV has no picture or sound. Was working fine then suddenly went black. Slight smell or something burning and just a clicking sound inside TV now. Any thoughts?

if it is 46F500 UNPLUG SET and remove back cover--on far right side as you look from the back you should see either two smaller or one very large heat sink with fins--the set listed has either one or two STK-392-110 OR STK-392-150 CONVERGENCE CHIPS.

Near them you will see about 12 resistors--look to see if any are burnt or slightly discolored in the middle---you have to look close at them--they can all be checked like checking a fuse--no reading and one is gone----

Point here is if any are bad or smoked--one of the convergence chips got them----the only other way to prove or disprove this is to get at the chips and un-solder all 18 pins on each chip--if set turns on--one is bad and BOTH NEED to be replaced along with any bad resistors--if you smelled something--something toasted--- these resistors are FLAMEPROOF or metal oxide--they will not catch on fire, just pop and go instantly.

Let me know what you find and I will help you--I am here to help people---If this helps you rate this solution as I do this here for free.

TV Exploded

Sounds like the DLP lamp failed. You can decipher the Hitachi flashing red light. That should help to be sure.
The DLP lamp replacement is fairly straightforward and can be done with minimal tools

Tv made a noise and shut off

I would first suggest checking the lamp and see if it has gone out.
If this is not the problem, then I would suggest calling a local service center to come to your home to diagnose the problem.

I hope that this helps.

Could be many things (components) on the board - might be visible, look for burned mark. Careful with the high-voltage leads. if you don't have some knowledge of what you are doing, don't.

the clicking is the relay. I would suggest checking the voltage regulators and horizontal output transistors

No power all of a sudden

Check IC601, C603 for leakage, I601 and vertical pulse detector QN05

for poor convergence check RK42 for open circuit.
