I believe i have found why all this location mention for this board does not
appear like they should. Right now all the capacitor that jeff mention on his
reply does not match. Neither the resistor you mention or IC. Whoever work on
this set before adapted another board to this set. I just notice a little
sticker with the brand name of Mitsubishi model # CS-2720R. But on the back of
the
set and front says panasonics. Ain`t this some S***. Because the voltage
regulator is IC951, the filter capacitor is C953 and is value is 820uf 180V.
That`s where all the confusion was all about. This is why i need it the
schematics
because i knew something was fishy with this board. Especially when i remove
the control panel for the switches, all the traces on the board where cutoff
and the wires was solder individually to each switch.
Sorry for all this inconvenience. Now the new subject should be (Mitsubishi
mod# CS-2720R)
Jose,
Check and see if you have voltage on the 130v Reg. IC (IC801), pin 1 --158v,
pin 2--131.6v, pin3--0v, pin4--130.6v. If you don't have the input voltage
on pin 1, check R801(.82ohm,5w) and R810(4.7ohm,5w). The voltage readings in
the power supply and horiz. circuit are taken with respect to hot ground,
which is the negative side of main filter cap C805(470m-200v). Also I
presume you checked the H.O.T. for being shorted??
