[TechAssist] Zenith IQB32B44W

Module number  9-2105.  I still have this set with a very unusual chirping 
sound. High voltage won't come up, checked everything, even disconnected the 
tuners and replaced the vertical out. I.C.  Disconnect Module from set and hit 
power button, set pulsates with chirping noise. I can measure secondary 
voltages trying to come up from Flyback for a short moment then shuts 
down.(About 5 seconds)  When module is connected to CRT and Yoke, it comes on 
and stays on, but still no high voltage and chirping still there. I have audio 
when the module is connected and set won't shut down for about a minute or two. 
H.O.T gets very warm. I suspect the flyback. I called my parts distributor and 
ordered the original transformer (95-4438-02) and they sent me a 95-04622-01. I 
checked resistance between the pins and there not the same. I called Zenith and 
they said that 95-4438-02 which is obsolete crosses to a 95-4606-02 but is also 
obsolete (Set is only 2 years old). I have another unit in my shop with the 
95-4606-02 that works, which is supposed to be the sub for the 95-4438-02 and 
tried it in this module but didn't power up or start osc. and obviously no 
chirping. So I put the original back in and now back to the same chirping and 
no High voltage. Zenith want to sell me the whole module for 175.00 and I only 
estimated the job for 185.00   Has anyone had this problem with this type of 
unit or know of any suggestions. From now on, I am telling all my customers to 
stay away from Zenith products. Obsolete parts within 2 years, give me a break. 
Neil     Zenith, in my opinion has surpassed Curtis Mathis as being the worst 
set on the market.
