My rca 32F531T power and there is sound but no display does any know where i can get the schematic for this tv chassi # itc008gww
First make sure the filament is lit on the CRT. Just look in the neck of the picture tube. If lit, then verify if you have Hi-Voltage on the picture tube. When the set powers up is there a sound like rustling leaves, if you hear this it usually means you have Hi-Voltage. You can also hold your hand up to the front of the glass to check for any static electricity. If present, you could still have a missing screen or grid voltage on the CRT or you may have some kind of video problem. If you have no feeling of static or rustling leaves sound then the horizontal drive signal may be missing to the horizontal output transistor. At this point you will need the services of a competent TV service tech.
Note: Horizontal output transistors usually don't open, they short. When they do they will blow a fuse and you will NOT have either sound or picture, just a dead set condition. The hi-voltage D.C. from the main input power supply is filtered and regulated down from approximately +170volts to +130volts plus or minus some depending on the model and screen size of the set. It then goes through one end of the main hi-voltage winding of the flyback transformer and then to the collector of the horizontal output transistor.

Flyback Transformer
the horizontal output transistor is for ITC008
search these site you can find more info for your chassis

Isolate filament voltage from CRT,i.e. unplug Crt socket from pix tube.Measure filament voltage on CRT PCB.If present,suspect bad pix tube.If missing,solder any/all connects in filament circuit,meaning CRT board first then main PCB.
SOURCE: ..sounds like it is clicking on and off..on and off..etc.
How old is this TV?
Sounds like it has high voltage failure.
(If you hold your hand on the screen when you try and turn it on, do you feel the static? )
Unless the set is over 10 years old, I would overhaul the high voltage circuit. Should cost under $200 at a shop.
SOURCE: Part numbers
look above for answers /cz is .22mfd/16v cap and rz11 is a 15k -ohm resistor/st.
SOURCE: Plzzz help me!!!!!
Your defective has defective parts on horizontal section. You need to bring the tv to expert technician,
SOURCE: I need to know the
Hello
The number of horizontal output transistor is [TL 035]. If this number is not available, you can use exact substitute after reffering it to transistor data book and equivalents. OK.
