Sharp LC-52D65U--1 blink lamp error--cannot keep on.

[RCA2000]

I have this Sharp LC-52D65U set--and all I get is the 1 blink..which means lamp error. If I do the Input and volume down...it TRIES to come on, after a few seconds--I get a quick blink of the raster--then it goes down...BEFORE I see any sort of menu , etc.

I unhooked the error line from the master inverter--did not help. Obviously--the inverter is shutting down of its own accord. I have read there is a capacitor you can bridge that will keep the inverter from shutting down--and then you can see if you have a bad CCFL tube, etc--and see if the rest of the set works.

I have heard "C7558" but that was on a different set. I do NOT think that is the right one for this set. Does anyone here know what I am talking about--and which cap to bypass?

You need to find out what the IC number is for the Inverter PWM controller circuit first.
So how about the pictures of the boards?

Ok...here are a few pictures. One if of the back of the set. Not much to see...the signal board, T-con, PS and inverters..that's it.

A couple are of the inverter one shows the # on the inverter top board (the one with the drive ckts on it..the bottom is just a "slave".. One pic is a close-up of the area around the drive IC area on the main inverter..

Sorry...my phone camera is not very good...and zoom does NOT work. this is the best I can get. Hope it helps..

You need to get the P/N of those SMD ICs on the inverter board then look up the spec sheet to find out what they are.
