    i need the part # for the horz output also!

  • Eugene Merritt Nov 11, 2007

    RCA Part Number for Q405 is 268428 (untested)

  • Eugene Merritt Dec 09, 2007

    I rated it already has leaky diodes on switching
    transformer switching transformer has been
    a problem for years in thompson Rca etc
    set is junk HOT may not be bad no odor
    only reason I checked on the part# is
    because it was so cheap $5.at mcmonline

  • Eugene Merritt Dec 09, 2007

    Its a refurb sold at Walmart that I found next to a dumpster
    just barely over a year old.RCA is poison around here
    I am not going to bother with it unitl after the holidays
    then I might take another look at it
    PS In case anyone out there is looking for the
    transistor that is not mcmonline, its here

RCA 32V434T Q405 = 268428 confirmed,however the
initial cause of Q405 failure is bad flyback transformer
Part # 271996 Replace both at same time..........T.

    Any feedback would be appreciated...................T.

  • Vista Electronics Dec 09, 2007

    I have changed dozens of Thomson IHVT's that had no odor....

    Sometimes just the transformer is bad and transistor is still

    OK....Usually set clicks three times..............



    Leaky diodes related more in the past with failures in CTC169

    chassis....big screen and direct view..........T.



    I welcome your completed repair feedback...........

I need to know the datasheet for the horizontal's transistor for a tv RCA 32F531T, because I lost the replacement


Hello
The number of horizontal output transistor is [TL 035]. If this number is not available, you can use exact substitute after reffering it to transistor data book and equivalents. OK.

Hello,
The Horizontal Output transistor needs to be changed as it is most likely shorted. The current transistor on this set is a 2SD3402 (no longer available) it's new replacement part number is the 2SC5902.
Order 2 2SC5902 Horiz Output transistors.Replace the transistor by it self once and if all is ok then fine.
If not replace it again and also the the Flyback HV transformer. The HOT transistor is probably shorted again and the transformer is causing it.

Sounds like the high voltage stages aren't firing up. Could be a number of things: Blown fuse, bad horiz output transistor, bad regulator IC, bad flyback transformer.

The reason this happens is because the high voltage also supplies the rest of the voltages needed to operate.

The set tries 3 times to come on (3 blinks) if there a problem such as a short, it will cycle without turning on. Unfortunately your set is notorious for having bad flyback transformers. Most likely the horizontal output transistor is shorted as well. Common causes for your symptom are: LL05 (horiz out transformer) RCA part# 257805; TL 02 ( horiz output transistor) 2SC5148; and open connections on the printed circuit board at LL 04 and L14401 (coils) all of which can cause the horizontal output transistor to be shorted.

Part number


oh an easy one LOL That part # is 1-453-268-21 and available at http://www.partstore.com at a price of $82.12. One thing though Make sure you check the horizontal output transistor with all the leads disconnected from the curcuit as this part sometimes goes bad when the fly does. My regular practice with any flyback replacement is to automaticly replace the HOT(horiz. output transistor) as well as resoldering the hhorizontal driver transformer and the horiz. driver transistor. Hope this assist yout repair and makes a happy one. Thats what were here for! Good Luck.
