Re: RCA M50WH92S (DLP) - Will not turn on

Still no go - resistor is ok - R22 the R indicates decimal should read 0.22 Ohm (according to an EE in the family) I checked the color wheel - it rotates freely I also got a capacitance meter & checked all capacitors on the power supply - ok The darn thing just won't power up - on the power supp...

The white box resistor on the upper left says 18R on it but only reads 0.3 ohm - the other white box resistor says 22R & read 22 ohm - is there something wrong with the first one or does it need to be removed to check? Its the power supply board I couldn't get this description to show up in prev...

Darn

Actually when I take it out of the board & test - it reads fine - 323 Kohm

Do resistors typically have to be removed to be tested? Is it significant that the reading goes to infininty while its in - are we on the track of the short?? Help!!!

Resistor Bad??

R819 - located on the right of the centered upper heat sink - its one of two pink resistors (orange/orange/yellow/gold striped) & it reads infinity the matching one a bit to its right reads 319 ohm - Can this be the problem? It may have been touching the heat sink - still reads bad when I moved ...

RCA M50WH92S (DLP) - Will not turn on

Upon plugging it in the power light is lit for only about 5 seconds & then shuts off. If I push the power button again it will light for 5 seonds & then click - goes off. No whirring sounds, no blinking of the power button light - lamp looks good. Any suggestions appreciated!
