The mitsubishi VZ5 chassis that will not power up often is the result of a leaky diode raising the voltage on IC700. A quick check is to check pin 4 of IC 700 for
0 Volts DC. If pin 4 has any voltage replace Diode 980 on the main PCB it is leaky and the set should power up. This tip relates to all VZ5 chassis mitsubishi's

Hi,
I have a Mitsubushi model VS-60603, the problem about this TV it is not power on, i was checked and found the R990 burned, this R990 is next to Diode 980, you are giving this solution about this problem, i am going to change this diode, but as I told you the R990 is burned and i don't know what is the value for this resistor, could you tell me please the value of the R990 and if is correct change this diode 980?
I will appreciate if you send me your answer to my email roger2730@hotmail.com , thanks a lot

Sorry i have another question, i don't know what is the thing soldered above the diode 980 is look as a resistor because this componente is damaged, the cover (ceramic is broken).....Could tell me what is it, please?
