No Picture, good audio

Below is a question I posted before and was advised to check the board connections and they are good. Could it be the main board tuner unit. -----------------------------------------------------------------
I have a Toshiba 37HL67S LCD and it has audio but no picture. When you turn it on the screen lights up and if you hit the input button it must go through the inputs because I can get the audio back on the input thats hooked up. I can also see the screen change somewhat when doing this but there is no picture on any input I use.The power light is fine. Could it be the main board tuner unit.

Hi,

The backlight in the panel is faulty or one of the surrounding assy boards are faulty.

Seek out an engineer as it not an easy fix and will cost you.

Thanks

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Model 42LE5400. Why no picture, no sound?


Just a guess (an iterative process)... but

Main board... EAX61532702
You MUST verify these numbers yourself.

If you are inclined to tackle this yourself... take a look at my 2 previous postings ... but I only GUARANTEE if you go in carelessly... you WILL turn your device into a pile of GARBAGE (good only for parts).

I was completely FLOORED to find reasonable prices at SEARS...
(guaranteed fit, (CALL 1-800-683-1693)).

Shop-Jimmy repair/return has kits(check out below).

Always use an ANTI-STATIC WRIST STRAP...Work safely (real pros REMOVE power (when possible))...

Good luck...

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and precious time.
