20 Most Recent Sony KP-48S35 48" Rear Projection Television Questions & Answers

i would say the bulb is on its way out and needs changing. on the back there is a hatch with one screw remove the screw and unclip the bulb holder, then pull out by the handle part number is on the bulb housing or the tv case.

I had a to go my pc display settings and turn on dual screens before the hdmi output socket worked. . At least it didn't cost anything!

In most cases the standby light might blink with different rapidity to indicate a fault relevant to the processor. It is possible that most of these indicate that there are errors in the processing section . Since there is a possible short or leak in the circuit the output driver section can take in huge current to trip the SMPS or from advice from the micro processor. Remove the power plugs and make sure that high voltage sections are discharged of the potential stored in capacitors. Look for visible signs of leak or of busted capacitors. Look for bulged capacitors or damaged components- burnt or busted. Use a multimeter to check the continuity or shorting in components, if so detach from circuit and test . If the voltage builds up and the set power ON and then shuts up then the suspected section must be checked in detail.

The processor must have the +5 voltage to the function properly , the +B and secondary voltages also must be checked to infer the fault. Trace with caution and in running through the signal path , circuit trail.

There may be one on ebay but a Sony Authorised Dealer will be the best starting point.

red picture tube might have shorted to the point where it pulls too much current not letting set come on. J.D.W.

Try this link after you count the blinks.

the tv is telling you that the crt bias is incorrect, if i'm right the auto focus will stop part way through.

this is the link for the fresnel screen but i myself am trying to find the lenticular screen but so far no luck

This is not for the protective screen this part # is for the fresnel screen part # 405845511

The fresnel screen and the lenticular screen. The fresnel is part # 405845511 and is about $160 new. The lenticular is # 405845411 and is about $330.

someone shot your tv.





no really, I am just a smart a$$ --- but the loud pop sounds like it may have been one of the capacitors in the power supply board. check for a POPPED cap (rare) and if there is one, test the components in the related circuit - as SOMETHING had to happen to make a cap fail like that - maybe a voltage regulator? give it a look..

Since this recovers on its own, there are a few possibilities:

1) There are bad connections on the board that self-correct as the unit heats up a bit.

2) There are capacitors in the convergence and pincushion circuits that are starting to fail.

If you can solder, you can repair this yourself. First look for poor solder connections that appear to be grainy or have rings and resolder them. If that fails to resolve the problem, we next have to look for failing capacitors. I will look up the most probable caps in both circuits and post the circuit designations here.

Keep up posted on your progress.

STKs can also shut set off BIG black ics,also check pico fuses.

Called Sony, I'm sending them my G Board to get it refurbished for $100 - that should do it.
