No sound on hitachi 53sdx01b

No one has it in stock--board should be repairable unless lost etc.

You might also contact PTS Electronics who repairs boards and may have one of these rebuilt as well.

If its the board with the RCA jacks it may be fixable.

This set had lots of audio problems- some idiot decided to put the entire audio circuit on a single compact board---it develops all kinds of bad solder connections on the numerous flat Pak chips on both top and bottom of the board.

Board no longer available from Hitachi (srs board) and rebuild usually is over 150 plus shipping.

We send the board out for that as I have seen top notch experts spend hours trying to solder the board and not after have a working set.

Hitachi just crammed too many parts in too small an area and the heat bakes the board---Understand I was seeing this failure when these sets first came out--failing after a week or two in someones home.

the problem here is Hitachi usually if it still has it sells all three screens as a unit---expensive.

You may want to search with GOOGLE the internet as some companies sell replacement "protective" screen replacements.

I have even seen one time someone found a piece of plexi-glass and had it cut to the exact size and thickness for a replacement.

Hitachi USA or Andrews Electronics in California who ships all over and is the largest OEM parts dealer in the USA.

You can also Google the brand/model number with replace mirror after it as there are some vendors on the internet who sell replacement mirrors.

let me know if you have questions as I am here to help you.

The tv have picture look like a bright dull hallow glow to the screen,yes,than the tv CRT tubes coolant chemicals is bad.Tries websites like Tvrepairworld.com,Tvrepairkits.com to buy a coolant kit to do the replacement.

Replace your STK ICs -STK392-110s use 120s
Mats has ICs 1-800-628-1118

2.5 ohm resister at 2 watts at R43 is bad on the 53sdx01b same boards as my tv , when mine went it was at 12 ohm instead of 2.5

i have a 50" r.p. Hitachi, kinda had the same problem, it would go off at different times and i't hit on the back and get it to come back on,but after awlhile i'd have to hit it more and harder to get it back on till it quit, the menu would come on and would show the video 1 ,3 and that in the corner.After paying $75 for a guy to say it wasn't worth fixing i tried myself. Not knowing what i was doing, i checked all wire plug connections. Found 2 that wasn't seated good replugged them and still didn't work then tried the bulbs, just kinda jiggled all 3 one didn't feel the same so just tapped on it alittle and it popped, i guess back into place, anyway turned on the tv and it worked. Had moved it recentlly so i don't know if that is what moved the bulb. Hope this helps, also mine is a '94 model.

theres a digital switch IC on or near the AV panel that needs to be replaced if I`m understanding your question correctly you go into menu and switch to Ant. B & there is sound but no picture correct? If this is correct the IC will have to be replaced or it`s supply voltage is missing.

after failure press the MENU and INPUT(or DEVICE whichever you have) and count the blink sequence there will be a first set ans second set of blinks. this will be an error code.
