Subject: [TechAssist] Sony KX2501 IC651
Sony
KX-2501
SCC-383A-A (HF chassis)
Cir early 80's
This is a sony 25" TV monitor with seprate DIN connected
Tuner. Problem Dead or more specifically shuts down instantly. Will run at
85-90v on variac. Suspect IC651 Which is a DP6. HAve a photocopy of the
schematic portion. Now this module when pulled show the epoxy has been
heated and has cracked after a little pulling and tugging at the cracks
resintalled and the SEt ran the rest of the day. Any one know if this is
probabble or if this part is still avalible Subs have several earlier
versions ie -1, -2 , -4
