Horz. Output Transformer for a GE Mod#46GW945

Where can I get the following part
GE Mod. 46GW945YX1
Part # 215541
The numbers on the old Part are 30949060 M9813
Problem was shorted Flyback & Horiz output transister
The voltage on the horizontal output transistor collector 19v to high
spec says with color bars the Collector = 140v I measured 159.3v
also the Base = -0.07v I measured -0.026v Scope wave form should be
15v @10us I measured 12v@10us.
Removed Horz Output transformer secondary & meas. R. Should be 0.2ohms. I measured 0.1ohms
LOOKS Like transformer has a shorted winding !!
Thanks AL BD,WI

GE 46gw941

MOST likely a bad high voltage transformer or a Glycol leak both of which were common in this set and the parts for this set are nearly impossible to find (I think by the model number set is newer than 92).

I liked these sets but I would not invest big money to fix one this old.

After pushing the power button on there a chirping noise coming from the back of the tv and doesn't turn on.

hi, the chirping noise is either the switch mode transformer or the flyback transformer, more likely the flyback as thomson built sets are infamous for them failing, nothing you can do you`ll have to call a tech to verify which has failed, not a major repair job, gl, video-tek

Sony TV not working

This is not an easy fix for most people! I suspect the ps is blown, R607, Q601,Q602 (use all org Sony parts, lots of factory 2nds around). This stuff blows to protect the fuse!!!!! Very rarely the input bridge rectifier or filter cap short.
Check R622, if open or discolored also replace VDR601(doesn't go bad very often). Check Horz output Q502. Inspect whole board for any bad connections, all parts with heat sinks(regulator ICs). Horz driver transformer, 0.47uf to horz driver tr. There could be other parts bad (flyback??). Make sure no supplies are shorted, check audio output supply, vert output supply, etc. Easily $150 repair at a shop. Good luck!

Will not turn on.

  • proceed as given after your power supply is ok (your statement)
  • isolate power supply from h/output stage.
  • check diodes & capacitors connected with flyback transformer.
  • check for print short.
  • ckeck h/output transistor.
  • connect supply to h/output stage.
  • put on the set.
  • hope this will help.
  • good luck

still there is a drop in voltage then your fly back transformer faulty.
