sanyo eb8a28 chassis part va1601 what is it

<< < (2/2)

mulja:
Check resistors R606,R607 if Ok check all resistors
About IC shouldn't read straight across.
And you have 320v on C609 (400v270Mkf) capacitor?

ernie:
checked the resistors all ok now you confirm that the ic is reading wrong i have put one on order and hopefully after fitting that and another opto it works without blowing them.one more thing though their are two optos in it one on the power supply the other on the ht but both the same they have both got p421f on them does the replacement opto have to have the same on it as i have some optos but not that one but the one i have in mind reads exactly the same as the good opto on the ht so should that be suitable to go in the power supply,i know i should get a new one but its like getting blood out of stone to get shops to order the home engeneer things here.thanks again for your help

mulja:
No different bitween just should be 4 pin opto (from any power supply).
And check D615(18v zener) before replace IC.

mulja:
To ernie:
You fix that TV
Post your solution.
I will add in tv repair tips list.

ernie:
good idea just waiting for the ic to come and will let you know what happens    ernie
