Question about RCA F35317 35" TV

Possible picture tube problem

1st my picture all of a sudden became waterwashed the red was still visable but hazy. I believe I need the exact value for my tv model # f35317 for the param # 01-23 I don't want to guessimate I had I tech come out and he said it would cost 395 for some circit part for the picture tube but after looking at the labels or the TV we found one that said before assuming a picture tube problem try the front panel adjustments for the param # and select the proper value and now I need the values from 01-23 I have a list of the value Ranges but I would Like to have the exact number if possible.

Best thing to do if the eeprom is corrupt is to buy a pre programmed eepromed. They have the factory settings and you may need to tweek these setting depending on how old the set is. BUT i HAVE SEEN IN THE PAST A PEEP TRYING TO ADJUST THERE OWN SET WITH THE SERVICE MENU!!!!!dont do it. FIRST OFF THE # 1 THRU 76 ARE NOT USED AT ALL. It would be best to get an authorized RCA repair person who knows what they are doing with these sets. As theres several HI Voltage saftey issues with repairing a set with no user replaceable parts inside them. Good Luck

Sounds like the tech you had there isn't too familiar with the CTC chassis. I doubt that your problem is the CRT. RCA ctc chassis have a problem with the tuner grounds breaking and this allows pulses to spike on the data control lines for the eeprom which can reprogram it and cause just about any problem from a dead set to a perfectly normal set and everything in between. First this should be eliminated by opening the tuner cover on the bottom of the board and resoldering the 28 connections if necessary. If the tuner is ok then it sounds like the paramaters in the service menu should be checked. There is no perfect number to set the paramaters to. It depends on the characteristics of the unit and is different on each set and determined by the tech. The service manual gives a procedure but I've been doing it so long I can get the drives close enough by using the black in the picture as a guide for the individual drives (raise them till you see the color in black areas and back off till it just goes away). In most cases this is more than satisfactory. If the paramaters do not solve the problem you probably have a componenct failure. It should not cost much to repair no matter what it is. First get a new tech, one that is qualified, to look at it. Good luck.

Toshiba tv has dark picture cant hardly see want get bright

If it's a old style projection screen pry off front grid, you,ll see a trapezoidal mirror this often becomes hazed smoke, dirt, ect. Make sure set is unplugged DO NOT ASSUME THEIR IS NO SHOCK HAZZARD BECAUSE SET IS UNPLUGGED(see capacitors) be careful and clean mirror with damp cloth and glass cleaner try not to spray as safety percotion, their are 3 tubes red , green, blue, green is th dominaent color if you know how turn blue HVU UP 1st( CLEAN picture tube lens 1st) These type of picture tube have clear poly glycol ( anti freeze) in lens unit to cool and is part of the optical system. I this fluid becomes contaminated then cost of repair may exceed value of unit, then increase red value I just thought you may bee able to do the color via menu not sure, if picture has a green tent at start this should help good luck , lot me know what you see.

Convergence bowed

Hi

the coming out is glycol oil (coolant). If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. Some of the solutions described below can be dangerous, TV's are very hazardous to service. Even when plugged out, TV's can store very high voltages.

Looks like a picture tube problem.
Try to reduce the contrast, maybe it will be better.

Look into the three tubes while the TV is running, and observe the
picture quality of the three. If the red and green are crisper and clearer, and the blue's all hazy from bacteria growing in the coolant, then the fluid needs to be replaced. The CRTs of the colors that seem hazy need to be removed from the light box to be
serviced. The coolant needs to be drained, the CRT assemblies
disassembled and totally scrubbed clean and refilled, then reinstalled and converged. If the coolant is
clear, it can be a weak CRT.

Also the convergence STK ships might need to be replaced, and the soldering checked.

Good luck

Sony rear projection screen is red then tv shuts off

Can be 1 of 2 things. 1st the red tube just needs the voltage to it turned down. In the front of TV (you have to remove the lower front half of TV to access it) is a plastic square with 6 knobs. The from left to right top knobs control focus for blue,green red. The bottom knobs control voltage to each tube in same order (so lower right knob for red) turn SLOWLY to left to reduce voltage until excessive red and lines go away. If you over turn left or right set will turn off. If that does not fix it or if lines reappear then option 2 is that red picture tube is failing outright and needs replacement.

Absolutely right about the transistor and also check any adjacent resistors to the transformer and to the line output transistor. Good luck.

Sony KP-57 hw40 red picture tube... manufactured 2002

yes you would need a service manual and have to do all the alignments but it would need to be an exact match on the picture tubes as some sets have different components within the same mode year depends on serial number so be sure the replacement tube has the exact tube numbers that your tube has. it still is a very involved proceedure and the picture tube can and will hold a very serious charge and it can give you a severe shock if not handeled properly and discharged properly.

Screen became dim over time and then blank. Red LED lights blinks when on and sound is fine. Is this the bulb, unlike the others that went suddenly?

There is more than one flourescent tube in your TV, It could be possible that one after the other has failed, these should usually last a few years depending on usage.

If it is not the tubes then there may be a fault in the backlight inverter although this would more likely show up as a sudden failure.

Blue Saturation with retrace lines visable

could be but there are a few checks that need to be donr first.. Try to turn down the g2 control just a bit on the flyback transformer. If no effect unsoder the blure drive transistor on the crt board If the blue is still there that means the crt is shorted and you could try to clean the elements with a crt rejuvenator and see if that helps. If the screen goes to red and green after you disconnect the blue drive transistor then you need to check the osd drivers as well as the rgb output drive from the video IC. If the blue gun in the tube shorted or leaky I have in the past and it really works a isolation transformer that plugs in to the crt socket and the other end plugs into the crt. What this does is isolate the the gun of the crt from the filiments and thats where they get shorted or leaky but for how long it will last who knows.
