The tv turns on but no picture.

SOUNDS LIKE A CAPACITOR GOING DOWN ON BOARD OPEN BK LOOK FOR BULGING HEADS

Have same problem. Not the proper fix though I found that taking the back off and heating it up with a heat gun for 30 seconds to 1 minute and tv works fine till you shut it off over night.Maybe someone can offer a solution with that in mind. Pretty strange

Ur tv covergence board it is dying.Tv are developing a convergence picture problems.Tv have colors R,G,B lines mis alignments,have colors shadows pictures or 3D pictures look alike?Yes,than the tv convergence board it dying must require replacement like 2 STK convergence ICS and some or all of it resistors too.Fixed the tv convergence board to solved the tv convergence picture problems.The shop will cost u like $300-350 for parts and labors.

Had same problem Sylvania SRT2232s 32"had to keep powering on and off until it warmed up enough to finally stay on. Problem was the 100/50 & 1/50 filter cap took it to local repair total cost to fix was 74.52 works better than ever

if the sound goes out its not a tube problem . a bad tube would have no effect on the sound .you problem (my guess) is in the power supply . a modern tv power supply has parts of it that stay on all the time unpluging it is not the problem its when you plug it in ! the power supply gets a JOLT . you might get away with it ,you might not . thats why we install surge arrestors on power plugs and with expensive tvs i recomend a UPS a power unit that keeps the tv powered even wnen the line power is out . thats keeps everthing in the sets nice and even ,so the tv lasts longer ... a modern tv turned off uses about 1.40 in electric a YEAR in standby mode , so what are you saveing if you send you set to the landfill early and have to buy a new one ? over 1.40 in electric ? . turn down you water heater or something else simple dont be blowing out you electronics for the sake of a few cents ..... good luck .... if this answer helped please rate a 3 or 4 , this high rateing will hepl keep me in the paid answer department . thank you

possoble cold solder connections breaking when unit is cold they expand when hot thus making connection.

is the picture clear when on? if yes, does the screen go black after a few seconds. if yes, sounds like you need a back light inverter!

The repair kit comes with instructions for a skilled tech.......
Part # 483531057673 Horiz driver.......All L04.1U Chassis.....T.

Might be a bad CRT or bad video output IC that drives the CRT that would cause this issue.
