Ps61670 proscan tv

Set came in with usual high voltage snapping at anode replaced anode cap and wire and silicone set then fired up ok but with poor luminance , looks like problem where raster is similar to turning up screen control this was a common fault on older rca sets it was caused by a shorted buffer transistor. can not seem to isolate this one, i have a schematic on order,have checked all caps,coils and resistors in video area even changed out t-chip any one have a solution thanks tutt.

I Have A 1998 RCA Home Theatre TV Sound Works But No Picture And There Is A Snapping Sound And Light Or Ark Flashing Happening Inside

May be the high voltage lead(s) have popped off of one of the pix tubes...the flyback(HV) transformer may be can remove the rear cover and look to see what is very careful as the voltage may be as high as 25000 Volts...if one of the anode caps has popped off, then you will first need to use an insulated screwdriver that is grounded to the chassis through one of those alligator clip jumper leads..this process will discharge the unit to make it safe to work on the HV components...then you will need to pop the anode cap back onto the tube making sure it has a good tight fit...if the problem is elsewhere, you will need to call the serviceman for repairs

AKAI PT5492S - Makes a ticking noise,black

This usually is indicative of the EXTREMELY HIGH VOLTAGE anode connection somewhere between the flyback transformer and one or more of the crt picture tubes or the splitter. Being that this circuit has a running voltage potential of over 30,000 volts if you are not familiar with these YOU CAN BE KILLED messing with it!!! What happens is that there is a breakdown of insulation over time usually from dirt or other environmental contamination. Usually a good cleaning and replacing the HV anode wire that has failed. (hint) it will be the one that the "ticking noise" is coming from. The ticking noise is actually the high voltage arcing to the chassis/ground.

Be careful!!!!

RCA D52W20 has no anode cap (Discharge how)

On end of the red wire from the flyback to the top center of your CRT (picture tube) there is an anode cap. Get a wire clip and a long screw driver that has an insulated handle. Attach one end of clip wire to known ground on TV chassis and the other end to the screwdriver. Now carefully slide tip of screwdriver under the anode cap. You should hear a little snap. Now the CRT is discharged.

Good Luck, Big Irish.

Hitachi 51f59a lost picture powers up and can hear sound amp come on when turned on and off but no picture

You may have a shorted horizontal output transistor. This transistor drives the high voltage transformer which in turn drives the picture tubes. High voltage can be dangerous so you may want to have a repair shop check it out for you. Also have them apply a bead of silicon around the anode caps on the picture tubes. This will prevent high voltage leaking out and causing the horizontal output to short again. Thanks

Hi there I've noticed youve been really helpful so...

The )( is indicating your loosing High voltage required to pull the raster across the screen. This can be tweaked but a short lived solution. I suggest it may be a good time to start shopping.

Hitachi 51F510

The loud "pop" sounds like high voltage arcing coming from one of the CRT' may have to pull each CRT out and put silicon sealant on the anode connectors to prevent the arcing.(one of the CRT's may be arcing internally also and the only cure is to replace that CRT) If you let the arcing continue,it will short out the horizontal output transistor sooner or later.......

Proscan not turning on

Actually, the set has the PTK188AC chassis. This is a very uncommon chassis. The most common reason for the set not starting in that chassis is a shorted high voltage splitter. That is the large black box inside the set that has 5 thick red wires in it. When the set is turned on, the computer senses the short in the high voltage circuits and immediately shuts the set back off. When the set is on, that box has dangerously high voltage in it so it should only be replaced by a qualified tech familiar with the high voltage splitters in RCA projection sets.
