    Checking the crt board...one of the color amp transistors will not measure at collector and emitter. The transistor is good. Diode cr14704 reads leaky in circuit....checks out good out of circuit. Still searching.....will be sometime before i get back to you. I welcome any ideas Tanx jingjao

    The CRT board is good. The return voltage is not present between collector and emitter of Q15103. I still belive the FB is good...and the eeprom may be good. What are the chances U12101 is bad? What should I check before replacing the 52 pin IC?

    I replaced IC U12101. I now have a picture and can watch tv. The next problem [same tv] I am missing one color...The picture is of yellow shade. Do you suppose I need to replace the eeprom. And does the eeprom help shoot red, blue and green to the picture tube? I did check the tube and it is good.

    The CRT board is good. There is no return voltage on the blue color output transistor. The color blue is missing. Where would it be?

Kc LT-32x575. Turns on for 3-5 seconds with video then screen goes black but still have sound volume and channels change but no raster turn off and back on does the same every time


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

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.

Blue screen has audio can change channels and hear different audio but no picture


Hello
If you can see menu on-screen display, just get into it, surf for blue-back option and turn it OFF first, and see whether there is any grains appears on your screen. If there is no grains, and only a plane raster, your TVs video processor Ic has got damaged, and should need replacement. If there is grains, you just retune it in autotuning option, and allow it to store all the transmitting signals at that time. This process may take two or three minutes to complete, and you should wait till then. Never forget to connect antenna socket to the antenna terminal of your tv.
If you are using set top box, and connected it to the TV through audio-video cable, your TV has no fault, but the set top boxs' video processor has got damaged. OK,

RCA 32V434T (32'') TV has no Red or Green pixels, only Blue


The color problems are caused by cracked/broken solder joints on the circuit that controls the display.  Usually this is located at the back of the tube on a small circuit board. Your description suggests that only the blue signal circuit is intact. I suggest these joints be resoldered for more strength.
It's a possibility that another IC senses this problem (or another one) and then shuts down the system.
Resolder those joints and see what happens.

No picture


Possibly but I will need a great deal more informtion... When you say no pic, do you have any raster, blue screen or any light at all?? Sound - when you change channels does it appear to change or stuck on the same channel? If you look across the screen can you see an image of a picture - use a flash light in same direction - any image at all??

I have purchased the converter box to receive digital signals and my tv doesn't have the red/yellow/white connections. Is there a model of converter that will work on this tv which is an RCAModel F25423...


THE CONVERTER BOX HAS R.F. OUTPUT. JUST HOOK IT UP AND PUT THE T.V. ON CHANNEL 3.(OR WHAT EVER THE INSTRUCTIONS THAT CAM WITH THE BOX) YOU WILL NEED TO CHANGE THE CHANNELS WITH THE REMOTE THAT CAME WITH THE BOX. YOU MIGHT NEED TO SET UP THE BOX (SCAN FOR CHANNELS) THAT IS ALL IN THE INSTRUCTIONS THAT CAME WITH THE BOX.
