20 Most Recent Sony KV-35S42 35" TV - Page 3 Questions & Answers

the problem of your tv is the CRT socket replace the CRT socket it with a new one and your tv will fine.

your tv had a cold solder,so try to resolder the vertical ic. or vertical section as well.

tv wont turn on when i hit power it makes the clicking noise like it is going to turn on, but never does and the red timer light next to the power button just flashes.
help!

only clicks and blinks

You did not mentioned about in which source watching the Tv. If it normal cable Video if section may failure. Or from AV source CRT board problem.

This is due to screen control faulty or crt weak. Change the screen control and its related coupling resisters.

All the above connected method is correct. Need to change the option in the stereo system as md or auillary depends upon the model. Go through user manual for stereo system.

Due to vertical section failure horizontal line apprears. You did not mention about picture. Green horizontal line means with picture or without picture. With picture means there is some leakage. Without picture only singe horizontal line means vertical section totally not working. Particularly green horizontal line means maybe leads to jungle ic failure. Please mention your simptom clearly what you get and what you will not get both video and audio. It will be helpful to answer. Based on your question this is my small information.

First confirm the sound source is coming or not. This can be confirmed by connecting AV out from your TV to any other source input source like Amplifier or Hometheatre. If it comes there is problem in audio output section. Before proceeding the above method first check sound menu if any changes in sound system. Normally the sound is BG,I,DK. If there is any changes in these options sound will not come or getting distorted sound. I think above information is useful to you.

First we have to check whether the problem arrives from Source or audio output section. If you have Amplifier connect TV audio out to Amp. in. Now check difference as you said. Now the complaint continuous failure is from audio source orelse the problem in audio output section. This would be a worth to repair. Before to proceed the above things go through the audio menu and check the sound system like BG,I,DK depends upon your region. I think my information is littlebit useful to you.

POWER SUPPLY PROBLEM.YOU MUST HAVE SOMEONE REPLACE TWO TRANSISTORS,VARISTOR,FUSIBLE RESISTOR,4 CAPACITORS & HORIZONTAL OUTPUT TRANSISTOR & RESOLDER PINS ON HORIZONTAL DRIVER TRANSFORMER.GOOD LUCK.4TUNE

Your statement is not clear. Sound was working in stereo or mono mode. Whatever it is you said i hit button on the remote means which button. Suppose you got the solutions in multiple order combinations means there is dry contact in the mother board. If it is not there check the menu options whether the sound system is set in your type of reception if it is BG or I or DK.

Usually, the CRT is bad......re-juvenation is a temporary fix at best........try adjusting screen control on CRT socket module.

Only other possibility is solder pins of vertical output IC.

ON THE 36 INCH SONY THE PROBLEM LIES ON THE PICTURE TUBE.THERE IS A LEAKAGE EITHER HEATER TO CATHODE OR G1 INSIDE THE CRT.THE ONLY WAY TO FIX IT IS REPLACE THE CRT OR HAVE THE CRT GUNS CLEANED THRU PICTURE TUBE TESTER/RESTORER/REJUVINATOR AVAILABLE ONLY FROM TV TECHNICIANS.GOOD LUCK.4TUNE.

key2life316,
Your TV has a bad picture tube = no reasonable repair possible......time to go shopping!....................T.

Guest,
Your TV has a bad pix tube + a blown power supply!!
Time to move on ........T.

Basic repair for skilled TV repairman = solder connections on
vertical output IC.........Can be done in home.....T.

could be noumerous things: 1. check power supply, too high or too low voultage may cause TV to shut down. measure it to detarmine if power supply is faulty. 2. check convergence board. If either of these 2 fuses on the convergence panel are open then replace the STK output devices PLUS check for any resistors in that circuit that may have overheated and changed value. Use actual fuse values, putting in a larger fuse, even to try and diagnose problem, will cause more severe damage. 3. Check for bad solder connects on the PC board in the area of the power cord and related components.

On the CRT itself, without the socket connected, you should have continuity (0 ohms) between G1, G1-2 and G1-3. Those 3 pins are Grid 1 and are tied together inside the neck. You should also have continuity (maybe 5 ohms or so) from H1 to H2. Those 2 are connected to the 3 heaters (in parallel). When the set is on there will be 6.3 volts of high-frequency AC power at those pins, and you should NEVER try to pump more voltage to the H pins. If you clear out the continuity between the 2 H pins then you blow open all 3 filaments and the set is garbage. There should NOT be continuity of any kind between G2 and any other pin. If there is then the tube is bad and cannot be fixed. There should also be no continuity at all between any other pins. The good news is that from the voltages you posted, you have a heater-to-cathode short that developes in the green gun when the tube is warm. To remove this short, take a 22uF 250V capacitor and put an alligator clip from the negative lead to ground. Connect the positive lead of the capacitor to the 200 volt boost source and turn the set on, which charges the capacitor. Tap lightly on the neck of the CTR and when the voltage drops on the KG pin, the screen will go quite green and that is when you should take the positive lead of the charged cap and touch it to the KG pin on the tube socket. This should remove the heater-to-cathode short. A 22uF cap has enough charge to clear the short but usually not enough to blow open the filament itself. Using a capacitor larger than 22uF runs the risk of blowing the filament open and you do not want that. It is tricky to get it right because you have to have a charged cap and the tube must short out and you have to get the charge from the cap into the tube before the set shuts itself down. Try that and post your results.

You may have a bad connection inside the picture tube or a bad solder joint on the picture tube driver board which plugs onto the neck of the picture tube. Stargazer
