Watts of the resistors convergence tbl

After changing the chips , I found my 3 resistors open for the JVC convergence problem, 220,2.2 150 ohms for the blue color , but they don't have the watts or volt info. I 'don't find a local store to buy also.

Re: watts of the resistors convergence tbl

Give me the board location numbers and I`ll get you the info you need, (next to the resistors it will be printed on the board, )example: R100, R265, R565 etc. Let me know BMW Rider

Yes, they are in pairs(look at the 1/2 watt ones) and you will see two identical pairs with one for each chip---if I remember this model they may be 1.8 ohm----only very low value resistors will pop----also there will or should be a pico fuse for each chip on that board---orange or green etc that looks like a resistor and they may (going from memory) be marked 3a or 3 amp----both the resistors and the possible fuses can be checked with a meter----no reading and bad.

Have audio but no picture 51pp9303 replaced convergence chips and still same problem

Check all the low value resistors that are 1/2 watt around the chips--look for any slightly discolored-----most will be between 1.8 ohms and 5.6 ohms---often a bad chip will take one out---protection

Convergence Resistors keep burning up

Some simple advice---if resistors are smoking one of the chips is shorted----The set has two voltages that go to them--one a positive voltage and one a negative voltage.

If either chip is shorted you can replace the resistors all year and not get anything. The resistors are protection in case one or both chips short----

Remove all old heat grease and install two new chips and replace the resistors at the same time.

Note that the set may have pico fuses on the power board also.

I had a convergence problem on my JVC AV-48WP30, and followed the instructions posted by SD Tech. I used STK-392-150 chips and I replaced 1 burned out resistor that had no bands, but was marked 1.8 ohm J...

Yes, it does not happen often but you may have installed or got a new chip that is bad--you did apply heat sink compound to the new chips?

Check all the resistors carefully when you do this and double check all the soldering you do.

Let me know if you need help.

I just replaced the convergence board on my JVC AV-56WP74, but the red still won't line up. Are there other parts that should be changed?

you also need to check and replace low value resistors in that circiut.they are all 1 watt,usually they get discolored when stressed.R842 2.2 ohm,R854 and R846 1.5 ohm,R850 2.2 ohm,R858 3.3 ohm,R862 1.8 ohm.they must be the exact value available in MD from surburban electronics.please note stk392-110 upgrade to stk392-150 for future referance.ONCE AGAIN CHECK ALL LOW VALUE RESISTORS

Make sure you bought genuine Sanyo chips...if not goto and get theirs.

(2) STK392-110 Convergence Amp ICs
(3) 220 ohm 2watt metal film resistors
(3) 150 ohm 2watt metal film resistors
(2) 1.5 ohm 1watt metal resistors
(2) 2.2 ohm 1watt metal film resistors
(1) 1.8 ohm 1watt metal film resistor
(1) 3.3ohm 1watt metal film resistor
You can get the entire convergence repair kit which contains all the parts listed at the following link its called the AV48WP30 Convergence repair kit , but it applies to your model as well, and they include free installation instructions.

Jvc av48wp74 horizontal convergence unadjustable after after repair

you have to lift one side of the resistor from circuit in order to measure resistance otherwise a open resistor will not read open as you will be reading the resistance from the surrounding circuit. Always lift one side of a resistor out of circuit when testing with a ohms meter.
